Alien vs Triangles

Aliens vs Triangles uses hardware tessellation to create more realistic and dynamic characters in real time. The demo uses an innovative method of blending multiple displacement maps to create a transformation of the alien's skin. Touching the alien's shoulder starts the transformation that slowly travels over the skin, turning him into a brutal soldier. On the other side of his body, when his hand is touched, an infection moves up his arm until he is fully transformed into a completely different mutant character. A laser blaster reveals the multiple levels of skin that can be blasted away to reveal his metal skeleton. The damage happens on several layers of displacements, starting with blisters, muscles, organs, and finally the metal skeleton. All of this is seamlessly blended using a multi-dimensional tessellation engine on a single-skinned and animated character.

Highlights of the demo include:

  • Dynamic hardware tessellation to enable richer and more lifelike characters by dynamically increasing resolution based on eye-space distance, transformation maps, and damage maps.
  • Blending of multi-dimensional displacement maps to enable a single-skinned character to seamlessly transform using many displacement maps.
  • Tessallator knitting of each level of transformation and damage into a solid mesh, seamlessly integrating multiple displacement maps, tessellation amounts, and surface shaders.
  • Hardware tessellation for adding detail to the environment, optimized to add detail only where needed.
  • Seamless shader propagation and display of transformation and damage over a single-skinned character.
  • Animation blending driven by texture lookups into transformation and damage textures (using DirectX occlusion query).
  • DirectX Compute to calculate particle systems caused by laser blasts.

A Dynamic BRDF Display

Traditional computer displays are designed to be consistent in varying illumination and viewing conditions. But the real world does not consist of constant colors. It is filled with materials that reflect the surrounding light in characteristic ways. This new approach points the way to a future generation of displays that show the reflectance of materials instead of colors. The goal is to create a surface where the appearance and its relationship to the observer's position and the illuminating environment can be controlled dynamically. The display is based on a liquid surface excited by waves in a controlled way to achieve a varying degree of anisotropic roughness. The resulting probability density function of the surface normal is shown to follow a Gaussian distribution, through which it can be related to popular reflectance models (for example, the Ward BRDF).

Philipp Engelhardt is a "magician" who had an idea to animate eight polaroids that he found on the street. The result was an animated photo album narrating a new story in a new context. He combined, reconstructed, and repeated his own graphical material and the collected jetsam of pictures to reveal them in a new context. To the observer, the visible alterations in the picture are not immediately apparent; the manipulation is seen as the reality it superposes.

Chrysaora: WebGL Jellyfish Simulation

Chrysaora is a real-time jellyfish simulation created entirely with web technologies such as javascript, WebGL, websockets and CSS. It uses realistic rendering and simulation techniques similar to those used in modern 3D video games, but it can run in an internet browser on any operating system. It takes advantage of WebGL API to deliver real-time hardware-accelerated graphics to the browser. At the same time, Chrysaora uses the latest web-socket technology for full-duplex communication over a single TCP socket to establish real-time synchronization across multiple browsers. This enables the application to render different parts of the scene on multiple computers while they are being synchronized by a remote server in real time.

A Medical Mirror for Non-Contact Health Monitoring

Digital medical devices promise to transform the future of medicine with their ability to produce exquisitely detailed individual physiological data. As ordinary people gain access to and control over their own physiological data, they can play a more active role in diagnosis and management of their health. This revolution must take place in our everyday lives, not just in the doctor’s office or research lab. This project starts in the home environment by transforming everyday objects into health-sensing technology.

The Medical Mirror is a novel interactive interface that tracks and displays a user’s heart rate in real time without the need for external sensors. Currently, collection of physiological information requires users to strap on bulky sensors, chest straps, or sticky electrodes. The Medical Mirror allows contact-free measurements of physiological information using a basic imaging device. When a user looks into the mirror, an image sensor detects and tracks the location of his or her face over time. By combining techniques in computer vision and advanced signal processing, the user’s heart rate is then computed from the optical signal reflected off the face. The user’s heart rate is displayed on the mirror, allowing visualization of both the user’s physical appearance and physiological state.

This project illustrates an innovative approach to pervasive health monitoring based on state-of-the-art technology. The Medical Mirror fits seamlessly into the ambient home environment, blending the data collection process into the course of daily routines. It is intended to provide a convenient way for people to track their daily health when they use the mirror for shaving, brushing teeth, etc.

Enlighten Real-Time Radiosity

Using Geomerics Enlighten technology, this demo shows how dynamic real-time lighting enhances game play and visual quality in computer games. Enlighten is a cross-platform, real-time radiosity solution that can generate bounce lighting for a game level in a fraction of a frame. By combining Enlighten real-time radiosity with a fully dynamic lighting environment in Unreal Engine 3, the demo shows how lighting can add an extra dimension to the traditional first-person shooter.

The demo shows the death-match level on a CUDA research platform, which provides an insight into lighting in the next generation of top-tier games. The death-match level contains 100 fighting “bots”, each with a flashlight, sentry rocket turrets, and vehicles with headlights. All lights are shadow casting, and they bounce radiosity lighting.

Weapon fire and explosions contribute most of the lighting to the scene. Action-filled shoot-outs light up the screen, with the radiosity lighting providing most of the fill lighting. The player can control the lighting in the immediate environment through weapon fire and see the lighting from distant fights as it illuminates the level. Dynamic changes in the time of day change the mood and atmosphere in the game, and the demo compares the appearance of the game with and without radiosity lighting.

Device-Independent Imaging System for High-Fidelity Colors

This device-independent imaging system consists of a camera, which can accurately capture colors, and a display device, which can faithfully reproduce colors. To accurately capture colors, a camera with three sensors and three filters like conventional digital cameras was enhanced with color-spectrum sensitivities to satisfy the Luther-Ives condition. As a result, the camera captures colors with very high accuracy (for example, delta E = 0.27 in CIE L*a*b* for MacBeth Color Checker). The display component is a multi-primary color (MPC) display that employs more than three primaries (RGB + Yellow and Cyan in this case) to reproduce a wider color gamut with higher efficiency than conventional RGB-based displays. It can reproduce 99% of the existing material colors, most of which are located out of the color gamut of conventional display devices and cannot be reproduced correctly. The camera outputs signals in device-independent format (for example, XYZ), and the display prototype accurately reproduce those colors. The whole procedure, from capturing to reproducing images, works in real time.

0h!m1gas: biomimetic stridulation environment

0h!m1gas is a biomimetic stridulation environment based on the activity of an ant colony, under video and audio surveillance. The system archives the ants' movements and sounds inside a digital matrix. A pair of turntables constantly reacts to the colony's activities by spinning vinyl records and producing scratching sounds, similar to the original stridulations of the ants. Ants stridulate, human DJs scratch. This creates a sound-reactive space that reveals the connection between scratching, as an aesthetical expression created by human culture, and the stridulation phenomenon produced by ants as a modulation mechanism for communication.

GPU-Based Interactive Simulation of Liver Resection

This GPU-based interactive simulation of laparoscopic liver resection is implemented using the open-source SOFA framework. While similar medical simulators have been developed in the past, this demo relies on advanced methods and the computational power of current GPUs to simulate multiple organs with high-resolution deformations and collisions in real time. It is based on recently proposed methods: high-resolution Finite Element Model (FEM) with implicit time-integration implemented on GPU, volume-contact constraints, an efficient numerical solver based on asynchronous preconditioning, and improvements in visual and haptic rendering. And it uses detailed meshes generated from segmented CT scans to facilitate reproduction of patient-specific scenarios, which is necessary for pre-operative rehearsal of complex or risky medical procedures.

These methods allow real-time simulation of all organs in the abdominal cavity using an improved level of precision compared to previous systems. The FEM formulation enables reproduction of specific material properties. Contacts are handled by precise constraints with frictions on detailed surface meshes. Both methods efficiently support topological changes, as demonstrated by performing a resection of a portion of a liver, an important step in surgical procedures performed to remove cancerous tumors. Users can examine the mechanical and collision models, and the generated contacts while the simulated patient is breathing, and manipulate a laparoscopic instrument to navigate through the abdominal cavity, push on organs, and perform a thermal ablation.

This project is a result of a collaboration between INRIA and IRCAD within the EU-funded PASSPORT project.More information

Face-to-Avatar

This floating avatar system integrates a blimp with a virtual avatar to create a unique system of telepresence. The blimp avatar contains several pieces of equipment, including a projector and a speaker as the output functions. Users communicate with others by presenting their facial images through the projector and voices through the speaker. A camera and microphone attached to the blimp provide the input function and support the user’s manipulation from a distance. The user’s presence is more dramatic than a conventional virtual avatar (CG and image), because the avatar is a physical object and moves freely in the real world. In addition, the user’s senses are augmented, because the blimp detects dynamic information in the real world. For example, the camera provides a special floating view to the user, and the microphone collects a wide variety of sounds such as conversations and environmental noise.

Open House

Open House is an installation that allows visitors to telematically squat in a Florida home undergoing foreclosure after the US housing collapse. Virtual markets transformed this otherwise livable property into a ghost house. Prior to the collapse, movements of global capital seemed like a distant reality, but it was imaginary systems of value, not bricks and mortar, that asserted ultimate authority. Open House temporarily resists eviction by mirroring the market and creating hybrid subjects who occupy both virtual and physical space. Cross the threshold, open the door, flicker the lights, and rattle the shutters.

iMedic: Immersive Medical Environment for Distributed Interactive Consultation

This interactive medical visualization system is based on two hand-held tracked controllers that directly control the position and orientation of two 3D cursors. Button presses enable direct manipulation of space with either or both hands, resulting in intuitive manipulation of the viewpoint. You can place yourself anywhere at any orientation and at any scale with just a few simple gestures. A control panel, held in the left hand, acts as a container for tools and widgets such as sliders and buttons. For example, the widgets can be used to select various tools, or control transparency and rendering mode.

iMedic also includes the FilterBox, which enables radiologists to dynamically and simultaneously visualize multiple mappings of their data. They can see beyond obstructing anatomy to hidden or partially hidden structures, and they can quickly identify, isolate, and view structures of interest from any angle, which reduces the time-consuming need to reposition and rescan or physically inspect the patient.

The system uses several real-time raycasting shaders. These shaders include isosurface, transparency, maximum-intensity projection, and lit volumetric rendering, as well as hybrid shaders that combine these rendering methods. The shaders also support mixing of volumetric and polygonal data, which provides accurate depth cues.

iMedic currently supports several features including measurement (for example, linear, angular, and area), volume segmentation and editing, and multiple avatar collaboration. The software will be commercially available later this year.

FuwaFuwa: Detecting Shape Deformations on Soft Objects Using Directional Photo-Reflectivity Measurements

Soft objects are widely used in day-to-day life, because they are safer and more comfortable than hard objects. They also provide a natural and rich haptic sensation, so soft interfaces can improve emotional attachment and entertainment value in human-machine interaction.

The FuwaFuwa sensor is a small, flexible, and wireless module that effectively measures shape deformations in soft objects using IR-based directional photo-reflectivity measurements. Multiple embedded FuwaFuwa sensors can easily convert any stuffed object into a touch-input device that can detect both touch position and surface displacement. Also, since the sensors re battery-powered and equipped with wireless communication, they can be easily installed in any common soft object without affecting its soft properties.

Memoirs

Memoirs is an interactive installation that depicts humanity’s struggle to invent home appliances in pursuit of happiness. It is composed of a custom Polaroid camera atop a TV. As you approach, the camera takes a picture by recognizing your face. While a physically simulated photo paper falls down inside the virtual interior of the piece, digital data travel halfway around the earth to a web server. Like bringing films to the printer, taking a card with a printed web address from a stack creates a space in which to reminisce about the good old days.

HAPMAP

This navigation system enhances walking and sightseeing with a haptic technique that could replace maps. The system's natural, intuitive interface indicates subtle and complex navigation cues that follow the curvature of a road or path.

Conventional navigation systems tell users to “go straight” even when the road or path curves in one direction or another. HAPMAP presents complex feedback through a very simple design. By mimicking the operation and interface of sliding handrails, the it is intuitive and particularly useful for the visually impaired, who need these subtle cues to successfully navigate a winding path. It can present not only right- and left-turn navigation cues, but also subtle navigation cues for a winding itinerary. Using motion capture cameras, it also automatically controls the haptic feedback for real-time navigation.

HAPMAP’s simple design and construction is important to its ease-of-use and function as a portable navigation device. A large, heavy, and/or complex device would not be feasible in these circumstances.

A Look Under the Hood of Need for Speed: Hot Pursuit

Need for Speed: Hot Pursuit used image-based lighting for the forward-rendered cars to help them look integrated with the deferred-rendered environment, which dynamically changes with a full-day cycle of light and weather. A custom anti-aliased line-rendering technique greatly improved the aliasing artifacts that are common to deferred rendering.

The dynamic look of the game was enhanced with weather effects, including rain, snow, wet roads, lightning, and heat haze. A procedural sky and multi-colored atmosphere system included height fog. The post effects system included color grading, bloom, vignette, and a game-play-based treatment. Gamma-correct rendering and filmic tone mapping were used to ensure a good tonal response in the HDR range. Artistry was required to effectively manage a large number of visual controls, some changing spatially and some over time.

This demo features all the bells and whistles of this game turned up to 11. A special game build accelerates the time of day, turns on all the weather, and culminates in some action-packed racing and crashing with all the related effects spectacle.

InteractiveTop: An Entertainment System that Enhances The Experience of Playing Tops

Spinning tops have a long history as children’s toys. A top is a simple toy, but its behavior is unique compared to other physical toys. Its attractive behavior is based on the gyroscopic effect acting within the top. Children sense the force of the gyroscopic effect when they handle tops, which helps them discover a basic phenomenon of physics.

This project extends those experiences with augmented-reality technologies by providing visual, audio, and force feedback. Traditionally, the user applies an external force to the top, but direct touching often has the unintended effect of moving the top, hence limiting continuous interaction between the user and top. InteractiveTop is an entertainment system that supports virtual physical contact between the user and the top, which allows direct, prolonged interaction.

Raging Rapids Rides

This scene of a river flowing through a rough valley achieves a level of realism not seen before in real time. The river exhibits a variety of medium- and small-scale details, including breaking waves, waterfalls, foam, and splashes resulting from interaction with solids. The goal of the player or autopilot is to drive a boat past as many checkpoints as possible while avoiding falling rocks and logs as well as deformable water plants.

A hybrid water-simulation method combines a height-field grid with particles. The main body of water is simulated by solving the shallow-water equations on the grid. Four types of particles are auto-generated using physically inspired criteria. Wave fronts with slopes exceeding a limit emit particles to form breaking waves. Waterfall particles are generated when the water flows across steep terrain. Collisions of solids with the water surface produce splashes with a volume that depends on the impact velocity. When particles fall into the grid, they are turned into foam which is then advected with the horizontal flow of the water surface. When particles are created, they take away mass from the grid and deposit it again when they return. The system adds water-surface details using wave textures generated by an FFT-based simulation. Texture coordinates are advected with the water flow and regenerated periodically to reduce distortion. Rigid and deformable objects are two-way coupled with the height-field simulation. Solids alter the height and velocity of water, which in turn exerts drag, lift, and buoyancy forces on the solids.

The underlying simulation technique is an extension of Chentanez N. and Muller M., Real-time simulation of large bodies of water with small scale details, Proceedings of the 2010 ACM SIGGRAPH/Eurographics SCA.

Immersive Multitouch Workspace

This new system efficiently combines direct multitouch interaction and 3D stereoscopic visualization. Users interact by way of simple 2D gestures on a monoscopic touchscreen, while visualizing occlusion-free 3D stereoscopic objects floating above the surface at an optically correct distance. By registering the 3D virtual space with the physical space, the system produces a rich, seamless workspace where the advantages of both direct and indirect interaction are jointly exploited. In addition to standard multitouch gestures and controls (for example, pan, zoom, and standard 2D widgets), the system includes a dedicated multitouch 3D transformation widget that allows near-direct control of rotations, scaling, and translations of the manipulated objects. To illustrate the power of this setup, a demo scenario allows participants to reassemble 3D virtual fragments. The scenario unifies the strengths of both multitouch interaction and stereoscopic visualization in an innovative and relevant workspace.

RolyPoly

RolyPoly enables two individuals to “sense” the presence of each other even though they may be physically apart. This is achieved through the mirrored movements in a pair of RolyPolys. A gentle tap to rock one RolyPoly simultaneously rocks its partner RolyPoly to the same degree. Likewise, a sudden shake and rattle in one instantly produces a corresponding reaction in the other.

ISCAN3D and IFACE3D: 3D Scanners on iPhone by Digiteyezer

Thank to its embedded technology, Digiteyezer has invented a new concept for 3D scanning systems. The concept extends a new way of scanning to a wide range of users by delivering:

• Hardware-independent technology. Digiteyezer provides outstanding 3D scanning capabilities by using mono-lenticular systems like those in smart phones, DSLR cameras, webcams, embedded cameras (TVs, PCs, game consoles), and industrial cameras.

• 3D reconstruction with an automatic online process. Digiteyezer's architecture relies on an online reconstruction process for 3D models.

• Ease of use and user-oriented technology. Digiteyezer uses an embedded human interface that delivers 3D scanning capabilities to a wide range of users.

• 3D models with lifelike (or photo-realistic) rendering. Digiteyezer's technology allows creation and display of 3D models with a lifelike rendering, which gives users a brand-new relationship to 3D models. For example, when the applications are people oriented (face scanning, medical apps, fashion apps), the user experience is much more intense, because users see themselves as they are in the real life.

MoleBot: Mole in a Table

Many previous explorations of shape display (Feelex, Pop Up!, Lumen, and Relief) adopted the principle of the pinscreen and tried to develop a rigid yet flexible surface that renders dynamic three-dimensional forms in the real world. These shape displays involve hundreds of pins separately actuated by an elaborate mechanism. The MoleBot combines higher actuation speed, greater resolution, and smaller pixel size than demonstrated in previous projects, plus enhanced physical interactivity with objects on the table surface. It is based on a new shape-display method: a two-dimensional translating cam (mole cam), 15,000 closely packed hexagonal pins equivalent to cam followers, and a layer of spandex between the mole cam and the pins to reduce friction.

The MoleBot can interact with physical objects in two ways. The force from the mole cam can push objects or pull something sensitive to magnetism with a neodymium magnet. It could be a new game interface, in which people build a small world on a table by replacing hexagonal pixels with different types of small props and enjoy playful physical interactions between the MoleBot and objects in the real world.

Mommy Tummy: A Pregnancy Experience System Simulating Fetal Movement

Mommy Tummy is an interactive system that simulates pregnancy. A user wearing the Mommy Tummy jacket can feel the fetus’s temperature, movement, and heartbeat, and, by rubbing the jacket, communicate with the fetus. Within a few minutes, the jacket's weight and size change, simulating fetal growth over nine months. An auxiliary screen displays the condition of both the fetus and the mother in each simulated month with a 3D model of the fetus. The moods and activity of the fetus are displayed in a natural manner to simulate normal fetal development.

There are two types of fetal movement: kicking and wiggling. Achieving a kicking simulation is not so difficult, but wiggling simulation is not simple. It was achieved by using a technique inspired by the tactile funneling illusion (PhS) initially discovered by Georg von Bekesy as a type of illusory tactile sensation that arises between two points of simultaneous vibration or electric stimulation. Using PhS, Mommy Tummy simulates a wiggling sensation through continuous, temporally displaced operation of multiple air actuators.

When the user moves violently, the fetus enters a bad mood state and makes intense movements. On the other hand, when the user caresses the abdomen, the fetus enters a good mood state and makes steady movements. Heavy physical exercise is discouraged until a stable period is reached.

Photochromic Sculpture: Volumetric Color-Forming Pixels

Color-forming reflective displays like E Ink are easy on the eye even in bright environments. Applying photochromic materials (PM) and projected-light systems to this type of display makes it possible to control color without contact with the display surface. In this project, the concept of “contactless color control,” is extended to volumetric space to create “volumetric color-forming pixels”. The result is “photochromic sculpture”, which can generate a dynamically changeable 3D object.

The system consists of two components:

• A presentation component composed of laminated transparent plates coated with PM granules and Spiropyran, which produces color under ultraviolet light (UV) and gradually becomes colorless and transparent when the UV light is blocked

• A control component for manipulating projected light.

The project team is developing a projector that can provide a more complicated UV pattern and investigating how to create larger-scale photochromic sculptures in outdoor locations.

Third Skin

Third Skin captures imagery of our social, digital, or urban neighborhoods and interiors, and transfers them to fabric and dress design. It plays with Marshall McLuhan's idea of "clothing being an extension of skin, in the way that media are an extension of the body". Photography, surveillance, and online footage become the source for hand-manufactured dresses as media narratives. They map the collective and shared (image documentation, digital and physical scenarios and objects) onto the domestic: a one-off garment as individual statement and choice.

PocoPoco: A Tangible Device That Allows Users To Play Dynamic Tactile Interaction

PocoPoco was created by a research team that focuses on interfaces that can change their own shapes dynamically. It is a box-shaped device that uses built-in solenoid actuators to control the movement of cylindrical units and deliver dynamic tactile sensations.

With its simple, intuitive tactile interface, PocoPoco can be used in a variety of applications that would normally employ a more "functional" device, such as a keyboard, that allows users to engage in a virtual world without being conscious of their physical manipulation and sensory input/output experience.

A musical variation of the system, PocoSeqencer, allows users to easily create aural and visual components of a performance at the same time by simply pushing cylindrical actuators.

Recompose: Direct and Gestural Interaction With an Actuated Surface

Recompose builds on the Relief table developed by Leithinger. The table consists of an array of 120 individually addressable pins, whose height can be actuated and read back simultaneously to provide both input and output. Recompose extends this concept by placing a depth camera above the tabletop surface to detect basic user gestures.

The combination of direct manipulation, I/O coincidence, an instantaneous feedback loop, and gestural input is a largely unexplored research area. Recompose explores this area through a system that leverages the strengths of these interaction techniques. It uses a grammar of gestures to explore basic functions for interacting with an actuated surface. Initial explorations show that the most fundamental set of gestures includes: selection of a subset of the surface, translation of the selection, rotation of the selection, and scaling of the selection.

Recompose moves digital modeling into the physical space by adding intuitive hands-on design. This approach may contribute significantly to fields where rapid iteration and visualization are fundamental to the process of learning and creation, including (but not limited to) architectural design, three-dimensional product design, and medical imaging.

Surround Haptics: Sending Shivers Down Your Spine

Surround Haptics is a new tactile technology that allows generation of high-resolution, continuous, moving tactile sensations anywhere on the human body. The technology is inexpensive. It can be used with a broad range of off-the-shelf tactile actuators. It is compact. And it can easily be integrated into clothes, furniture, accessories, hand tools, mobile devices, and game accessories, among other potential applications.

Surround Haptics could become a key technology in a new generation of home-gaming platforms that integrate highly detailed and dynamic tactile experiences with full-body motion controls, stereoscopic visuals, and spatial sound. This demonstration presents two examples:

• A modular home tactile display: a custom plywood chair that can also be used in daily life, soft pads for the seat and backrest with embedded tactile grids, and a wireless control board. The user controls the game with full-body gestures using Microsoft Kinect.

• A high-intensity driving simulator game, Split/Second by Black Rock Studio. A broad range of game events was enhanced with complex tactile sensations, including collisions, road imperfections, tire traction, skidding, ripples of landing forces, acceleration, braking, falling objects, damage, etc. This multi-sensory gaming experience produces a deep sense of immersion, believability, and excitement.

The Surround Haptics technology is based on new models of tactile perception that were formulated in a series of rigorous psychophysical studies. These new models further expand and deepen our understanding of human tactile perception.

Travel Stones

Travel Stones are fictitious cultural artifacts presented in the style of a museum exhibit. The imagined culture derives from an ancient people who carry their travel stones, like house keys, as a way to access their home center that is ultimately more spiritual than physical. Passed from generation to generation, the stones further serve as resonant objects in the tracing of the people's history. Prompted by the drawings on the stones, the ancients recount tales of their origins to the next generations as well as to those they meet in travel.

Telenoid: Tele-Presence Android for Communication

This new system of telecommunication focuses on the idea of transferring human “presence”. A minimal human conveys the impression of human existence at first glance, but it doesn’t suggest anything about personal features such as gender or age. The minimal appearance allows people to use Telenoid to transfer their presence to distant places regardless of their personal features.

Telenoid's tele-operation system is simple and intuitive. It can be controlled by even novice users. Its face-tracking system automatically captures the operator’s facial movements and expressions. Field tests revealed that most users tended to have a strange and negative feeling impression of Telenoid in the beginning, but eventually they became comfortable. Elderly people had very positive feelings about Telenoid at first sight.

Wait

The companion-species relationship is the starting point for the critique explored in Wait. Human and canine communication methods are brought to bear within this interactive video installation. Taking cues from the movements of the visitor, the dog (as imaged in the video) points to the relationship of control. The dog appears to be waiting for direction; as the dog looks directly at viewers, a state of suspended agency is implied, and viewers are compelled to ask questions about their relationship to the dog. Wait was produced in co-production with the Banff New Media Institute.

Thermal Interactive Media

The Thermal Interactive Media (TIM) display is a multi-sensory experience that combines beautiful visual elements, the soothing touch of water, and the bubbling sounds of flowing water combined with the gentle clacking sound of deer chasers.

The display consists of a horizontal rear-projection screen covered with a thin layer of water and two basins filled with water, one on each side of the display. One basin is filled with hot water, one with cold. Mounted above and pointing at the screen is a FLIR thermal imaging camera. Driving the whole system is a PC workstation generating two simultaneous video streams, one “hot” and one “cold”.

Users can choose to pour hot or cold water onto the display, using ladles in the basins. Wherever the user pours in hot water, TIM displays the “hot” video stream. Wherever the user pours in cold water, TIM displays the “cold” video stream. In the regions in between, the two video streams mix and swirl together based on the water temperature. By observing how the two video streams mix together, users can see real-world fluid dynamics in action and watch in real time as the thermal energy dissipates and distributes throughout the water. The experience is simultaneously magical, educational, entertaining, and relaxing.

For an extra level of fun, users can don ChromaDepth glasses to augment the experience with a pseudo-stereoscopic effect. Regions of warm water colored red float above the screen and the cool regions of water colored blue punch holes deep into the surface.

Touch Interface on Back of the Hand

This new computer-human interface uses the back of the hand for inputting data.

Many touch-based interfaces present various types of buttons on small screens. But there is one drawback with this approach. Users cannot feel haptic feedback (“clicks”, for example), because the displays do not have physical buttons or provide any visual or auditory cues. Using our skin as an input surface can solve this problem, because we can feel and know which area is tapped.

Building on previous studies that used human skin as an input interface, this project focuses on the opisthenar area (back of the hand), which is relatively flat and convenient. Users can feel precise tactile feedback since the skin on the hand is more sensitive than skin in other locations. One potential advantage of this approach is that many people wear wristwatches. If those devices could be enhanced so they can detect finger position on the opishtenar, additional external devices will not be necessary.

True 3D Display

This research team was the first to use laser-plasma technology for a true-3D display device that allows users to draw 3D images in midair (True 3D Display Using Laser Plasma in the Air, Emerging Technologies, SIGGRAPH 2006). Now the team has developed a much more compact and precise display, called SRV (Super Real Vision)-5000, based on advanced laser technology. One remarkable feature of the new device is its enhanced resolution: from 300 points per second to 50,000 points per second. It displays 3D objects more faithfully in real time and increases the range of possible applications.

Vection Field for Pedestrian Traffic Control

Public pathways can present difficulties for pedestrians (for example, congestion and collisions). Although visual signs and audio cues are commonly used to encourage smoother pedestrian flow, they are often ignored or neglected because they require some time to be understood. For more intuitive navigation, wearable devices have been proposed, but these personal navigation devices, some of which induce motion by haptic or vestibular cues, are not suitable for congestion scenarios because numerous devices are required for controlling pedestrian flow, which is quite impractical.

This project focuses on large moving visual cues, which induce a sense of self-movement. For example, a large right-moving image on the floor induces a shift of walking direction to the right, even if the pedestrian tries to walk straight. Because it does not have a power source, the system uses lenticular lenses containing images of striped patterns. When pedestrians walk forward, the stripes shift to the right, and so do the pedestrians. The configuration is exactly the same for two opposite-facing pedestrians. 

The Vection Field has four advantages. It achieves intuitive navigation that does not require conscious recognition. It does not require wearable devices. It does not require a power supply. And a single sheet of lenticular lenses naturally works for pedestrians walking in both directions.

The Cyclone Display: Rotation, Reflection, Flicker, and Recognition Combined With the Pixels.

Cyclone Display has three significant points in comparison to other displays:

• It has rotating pixels made of patterned paper disks.
• Flicker and body movements (eye blinking or hand waving) can change the appearance of the disk patterns.
• It uses lighting conditions to display recognizable scenes.

The pattern variations in the disks (determined by disk-rotation speed) create a display. Flickering light is provided by a timed RGB projector.

The Virtual Crepe Factory: 6DoF Haptic Interaction With Fluids

The Virtual Crepe Factory illustrates a novel approach for six-degree-of-freedom haptic interaction with fluids. It showcases a two-handed interactive haptic scenario: a recipe that uses different types of fluid in order to make a special pancake (a "crepe"). The scenario guides the user through all the steps required to prepare a crepe: from stirring and pouring the dough to spreading different toppings, without forgetting the always-challenging flipping of the crepe. For the first time, users can experience 6DoF haptic interactions with fluids of varying viscosity. The technique is based on a smoothed-particle hydrodynamics (SPH) physically based simulation.

Volumetric Display Based on Vibrating Mylar Beam Splitter and LED Backlit LCD

This new volumetric display produces full-color, high-spatial-resolution aerial images out in front of the apparatus. It is based on a new optical element: the large, tunable-resonance, edge-driven, varifocal beam splitter.

Previous varifocal systems stretch an opaque Mylar mirror over the aperture of a loudspeaker. The speaker vibrates the mirror. making it alternately concave and convex. A synchronized, high-speed (oscillograph) image is viewed in the mirror and swept in depth. This type of display was commercialized as Spacegraph 3D in the late 1970s, but a number of problems limited its acceptance. The loudspeaker was noisy. The image was virtual (behind the mirror), since the mirror curvature is insufficient to create real images. The systems had small viewing apertures, since the display blocked the user's mirror view. Non-standard (now obsolete) oscillograph displays were used, and the systems were bulky, since it was difficult to fold their optical paths.

This new display uses a circular Mylar beam splitter and adds a tension-adjusting metal hoop pressed against its surface. The beam splitter is adjusted, with high Q, to a specific resonance frequency. Three rim-mounted impulse drivers apply low-amplitude sinusoldal drive. Due to the high Q, the diaphram's sympathetic vibration is large. The beam splitter folds the optical path, and the system includes a fixed-curvature concave mirror to create real images that appear out in front of the apparatus. It produces high-quality 3D images that occupy a one-third-meter cube 1/3 meter out in front of the apparatus. The image is viewable over a 30 degree viewing angle.

Liquid Simulation With Mesh-Based Surface Tracking

Animating detailed liquid surfaces has always been a challenge for computer graphics researchers and visual effects artists. Over the past few years, researchers in this field have focused on mesh-based surface tracking to synthesize extremely detailed liquid surfaces as efficiently as possible. This course provides a solid understanding of the steps required to create a fluid simulator with a mesh-based liquid surface.

The course begins with an overview of several existing liquid-surface-tracking techniques and the pros and cons of each method. Then it explains how to embed a triangle mesh into a finite-difference-based fluid simulator and describes several methods for allowing the liquid surface to merge together or break apart. The final section showcases the benefits and further applications of a mesh-based liquid surface, highlighting state-of-the-art methods for tracking colors and textures, maintaining liquid volume, preserving small surface features, and simulating realistic surface-tension waves.

Introduction to Modern OpenGL Programming

OpenGL is the most widely available library for creating interactive computer graphics applications across all of the major computer operating systems. Its uses range from creating applications for scientific visualizations to computer-aided design, interactive gaming, and entertainment, and with each new version, its capabilities reveal the most up-to-date features of modern graphics hardware.

This course is an accelerated introduction to programming OpenGL, emphasizing the most modern methods for using the library. In recent years, OpenGL has evolved and fundamentally changed how programmers interact with the application programming interface (API). The most notable change was the introduction of shader-based rendering, which has expanded to subsume almost all functionality in OpenGL. The course reviews each of the shader stages in OpenGL and how to specify data for rendering with OpenGL. And it summarizes how OpenGL's wealth of new functionality and features enables creation of ever-richer content.

3D Spatial Interaction: Applications for Art, Design, and Science

3D interfaces use motion sensing, physical input, and spatial interaction techniques to effectively control highly dynamic virtual content. Now, with the advent of the Nintendo Wii, Sony Move, and Microsoft Kinect, game developers and researchers must create compelling interface techniques and game-play mechanics that make use of these technologies. At the same time, it is becoming increasingly clear that emerging game technologies are not just going to change the way we play games, they are also going to change the way we make and view art, design new products, analyze scientific datasets, and more.

This introduction to 3D spatial interfaces demystifies the workings of modern videogame motion controllers and provides an overview of how it is used to create 3D interfaces for tasks such as 2D and 3D navigation, object selection and manipulation, and gesture-based application control. Topics include the strengths and limitations of various motion-controller sensing technologies in today’s peripherals, useful techniques for working with these devices, and current and future applications of these technologies to areas beyond games. The course presents valuable information on how to utilize existing 3D user-interface techniques with emerging technologies, how to develop interface techniques, and how to learn from the successes and failures of spatial interfaces created for a variety of application domains.

Successful Creative Collaboration Across Time and Space

Twenty years ago, large projects in computer graphics animation, game development, and visual effects typically involved a half-dozen artists and engineers working together in a single studio space. Ten years later, the size of project teams had grown to include sometimes hundreds of collaborators, but the work remained largely housed within a single campus. In 2011, many projects, large and small, are distributed across multiple locations and time zones. Facilitating creative problem solving among team members remains the key to success, but the tools and behaviors within the creative process are changing dramatically.

This panel discusses issues surrounding globally distributed projects in animation, games, and visual effects. Success in these ventures depends on unique production structures, review processes, universal tool sets, and adaptation of artists and engineers to technology-mediated communication. Topics include speculation on possible future work environments and how the rising generation of artists and engineers will influence the collaboration process. Each panelist brings a specific area of expertise to the general topic and represents an organization recognized for successfully advancing industry capability with distributed projects.

PhysBAM: Physically Based Simulation

This course is as an introduction to the PhysBAM simulation library developed at Stanford University and used in both academic and industrial settings, including Intel Corporation, Industrial Light & Magic, Walt Disney Animation Studios, and Pixar Animation Studios. The course contains information on the release of PhysBAM as well as information on how to obtain the source code, set up the library, and use it to run example smoke and water simulations. It also summarizes a visualization tool and a rendering tool included in the release of the library.

Physically based simulation is a vital part of the special-effects toolkit. Traditionally, special effects are obtained by constructing scale or full-size models, whether the scene calls for a sinking ship or a burning building. Unfortunately, this is very expensive and at times not feasible. Physical simulation is also used for special effects in animated films,
where traditional special effects methods cannot easily be applied. And it is increasingly used in the gaming community as enhanced processing power enables simulations to occur at real-time rates.

In addition to the PhysBAM library, the course explains the underlying techniques that make these simulations possible, in particular level set methods such as fast marching, fast sweeping, and the particle level set method. It also addresses the important aspects of a fluid simulation, including advection, viscosity, and projection.

Build Your Own Glasses-Free 3D Display

Driven by the recent resurgence of 3D cinema, depth cameras and stereoscopic displays are becoming commonplace in the consumer market. Introduced last October, Microsoft Kinect has already fostered gesture-based interaction for applications well beyond the intended Xbox 360 platform. Similarly, consumer electronics manufacturers have begun selling stereoscopic displays and inexpensive stereoscopic cameras. Most commercial 3D displays continue to require cumbersome eyewear, but inexpensive, glasses-free 3D displays are imminent with the release of the Nintendo 3DS.

At SIGGRAPH 2010, the Build Your Own 3D Display course demonstrated how to construct both LCD shutter glasses and glasses-free lenticular screens, providing Matlab-based code for batch encoding of 3D imagery. This follow-up course focuses more narrowly on glasses-free displays, describing in greater detail the practical aspects of real-time, OpenGL-based encoding for such multi-view, spatially multiplexed displays.

The course reviews historical and perceptual aspects, emphasizing the goal of achieving disparity, motion parallax, accommodation, and convergence cues without glasses. It summarizes state-of-the-art methods and areas of active research. And it provides a step-by-step tutorial on how to construct a lenticular display. The course concludes with an extended question-and-answer session, during which prototype hardware is available for inspection.

The Need for Standardization Within Global Visual Effects Productions Through Open Source and Open Standards

This panel highlights some of the open-source projects that are helping visual-effects companies share data worldwide and explore areas for future improvement. In most cases, production companies need to set up a hub to ingest data from sets and/or locations during principal photography, and then send and receive data from the various visual-effects vendors during post production. Because there is not much standardization in this area, a standard framework for information exchange could provide huge efficiencies for both production companies and vendors. The panel explores options for sharing assets such as plates, models, and textures as well as new issues related to stereo conversion.

The panel also explores two open-source initiatives:

• Image Interchange Framework (IIF), which provides improved color management within pipelines and between facilities as well as file-format specifications (a restricted EXR format) and metadata standards.

• Alembic, an open-source exchange format that aims to become the standard for exchanging animated computer graphics scenes between content-creation software packages and facilities.

Shadow Awareness: Enhancing Theater Space Through the Mutual Projection of Images on a Connective Slit Screen

This study presents media technology that enables improvisational and continuous creation of performers' physical expression as they are inspired by the imagery evoked from the audience. To realize this, the authors focus on "shadow media", a system that promotes continuous creation of imagery through "bodily awareness". The system projects shadows of the performers, which are then transformed into various shapes and colors. The shadows are connected to the performers' feet and projected on a "passable" slit screen set up between the stage and the audience. The result demonstrates that interactive and mutual creation of imagery from performers and audience can form an "empathetic" stage. To demonstrate its validity, the system was applied to a dance performance at Festival della Scienza in Genoa, Italy.

Art and Code: The Aesthetic Legacy of Aldo Giorgini

Working extensively as both artist and scientist, Aldo Giorgini was one of the first computer artists to combine software writing with early printing technologies. His innovative process consisted of producing pen-plotted drawings embellished by painting, drawing and screen-printing. In 1975, he developed a FORTRAN program called FIELDS, a numerical visual laboratory devoted entirely to art production.

This paper, the product of a multi-year study of Giorgini’s primary source materials provided by his estate, examines the methods he used during the 1970s to create computer-aided art. It is an attempt to ensure that future generations of digital artists, technologists, and scientists can learn about Giorgini’s aesthetic legacy and its contribution to the history of digital art.

The Readers Project: Procedural Agents and Literary Vectors

The Readers Project is an aesthetically oriented system of software entities designed to explore the culture of human reading. These entities, or "readers", navigate texts according to specific reading strategies based on linguistic feature analysis and real-time probability models harvested from search engines. They function as autonomous text generators, writing machines that become visible within and beyond the typographic dimension of the texts on which they operate. The system has been deployed in a number of interactive art installations where the aggregate behavior of the readers can be viewed on a large screen, and viewers can subscribe, via mobile devices, to individual reader outputs. As the structures on which these readers operate are culturally and aesthetically implicated, they shed critical light on a range of institutional practices, particularly those of reading and writing, and explore what it means to engage with literary components in digital media.

Special Effects With Depth

This session presents various graphics techniques using depth and normals buffers. The methods range from improving standard techniques such as particle effects to creating entirely new ones (for example, approximate volumetric effects), and advanced image post-processing. In many cases, the buffers used are natural products of the rendering pipeline and offer a way to infer a surprising volume of information about the scene, allowing for very rich and fast graphics effects. The session is designed for artists and programmers. It discusses the possibilities of the post-processing effects and their technical side.

Pixar: "La Luna"

"La Luna" is the timeless fable of a young boy who is coming of age in the most peculiar of circumstances. Tonight is the very first time his Papa and Grandpa are taking him to work. In an old wooden boat, they row far out to sea, and with no land in sight, they stop and wait. A big surprise awaits the little boy as he discovers his family's most unusual line of work. Should he follow the example of his Papa, or his Grandpa? Will he be able to find his own way in the midst of their conflicting opinions and timeworn traditions?

Following the Canadian premiere screening of "La Luna", its director, Enrico Casarosa discusses the journey that led him to create this very personal short and demonstrates the singularly artistic style by which the film was crafted.

With the growing requirements of quantity and quality in urban content, there is an imperative need for alternative solutions that allow for fast, semiautomatic urban modeling. This course explains new modeling techniques for urban environments as an important complement to traditional modeling software. It explains how to use procedural, image-based, and simulation-based techniques to efficiently create highly detailed three-dimensional urban models for computer games, movies, architecture, and urban planning.

The course surveys five major topics:

• Urban layouts and road modeling
• Computational building design
• Image-based modeling of facades and buildings
• Urban simulation and visualization work
• Procedural urban modeling in industry

Advances in New Interfaces for Musical Expression

Advances in digital audio technologies have led to computers playing a role in most music production and performance. Digital technologies offer unprecedented opportunities for creation and manipulation of sound, but the flexibilty of these new technologies provides an often confusing array of choices for composers and performers. A decade ago, the presenters of this course organized the first workshop on New Interfaces for Musical Expression (NIME), to clarify this situation by exploring connections with the better-established field of human-computer interaction.

The course summarizes what has been learned at NIME. Topics include the theory and practice of new musical-interface design, mapping from human action to musical output, control intimacy, tools for creating musical interfaces, sensors and microcontrollers, audio synthesis techniques, and communication protocols such as Open Sound Control (and MIDI). The course presents several case studies focused on the major broad themes of the NIME conference, including augmented and sensor-based instruments, mobile and networked music, and NIME pedagogy.

Stereoscopy From XY to Z

Stereoscopy has been very well known since the 19th century. The theory is very simple: just present a left view of a scene to the left eye, and a right view to the right eye, and the viewer's brain perceives the depth of the scene. In 2011, stereoscopy is everywhere: in the latest blockbuster movies, in theaters, at home on 3D displays, in games on all platforms, and even on the go with the new wave of capable portable devices. Though the concept is simple, realizing a comfortable and convincing stereoscopic experience for the user implies many aesthetic and technical considerations that revolutionize our way of creating graphics content.

This comprehensive course summarizes standard stereo-projection techniques, audience depth perception and comfort factors, recommended uses of depth as a storytelling tool, how stereo is used in gaming and real-time applications, details on conversion of 2D content to 3D, guidance on new creative choices, and using depth in an aesthetic way.

Multi-Threaded 2D Renderer Design
Rendering real-time high-quality 2D vector graphics through a 3D pipeline is a challenging task that requires custom algorithms for shape tessellation, edge anti-aliasing, and text rendering. For best performance, Scaleform 2D renderer includes optimizations such as multi-threaded rendering, mesh caching, and draw-primitive batching. Following a high-level design description, this talk dives into multi-threaded rendering, introducing a novel render-tree design that allows the both threads to access scene graph nodes simultaneously, greatly reducing copy overhead. This strategy is particularly effective when only a subset of nodes is modified every frame and can be applied to any real-time rendering engine.

Layered 3D: Tomographic Image Synthesis for Attenuation-Based Light Field and High Dynamic Range Displays

This method optimizes auto-multiscopic displays composed of compact volumes of light-attenuating material. Inexpensively fabricated by stacking transparencies, the attenuators recreate a light field when illuminated by a backlight. Tomographic optimization resolves inconsistencies between views, leading to brighter, higher-resolution 3D displays with extended depth of field and improved dynamic range.

Guerrilla: The Creation of Killzone 3 - Game Production Session

This talk details various aspects of designing and developing videogames at Guerrilla. It highlights methods that are very similar to methods used in the CGI industry, and it illuminates some of the most important differences. And it covers the complete breadth of videogame development from artistic design to production pipelines and tool and engine development.

Filtering Approaches for Real-Time Anti-Aliasing

For more than a decade, supersample anti-aliasing (SSAA) and multisample anti-aliasing (MSAA) have been the gold-standard anti-aliasing solutions in games. However, these techniques are not well suited for deferred shading or fixed environments like the current generation of consoles. In recent years, industry and academia have been exploring alternative approaches, where anti-aliasing is performed as a post-processing step. The original, CPU-based morphological anti-aliasing (MLAA) method gave birth to an explosion of real-time anti-aliasing techniques that rival MSAA.

Most of these techniques share concepts and ideas, so the main goal of this course is to establish a conceptual link between them, identifying novelties and differences. The presenters explain how sub-pixel data can be used to improve quality and performance tradeoffs at post-processing steps, which is a cutting-edge research area today. The course includes an overview of both research and industry filter-based anti-aliasing techniques in games for all modern platforms (AMD and NVIDIA GPUs, PlayStation 3, and Xbox 360), low-level insight to ease adoption of these techniques and give attendees a complete concept-to-implementation roadmap, and deep quality, performance, and ease-of-integration comparisons of each technique.
