2D
Introduction to the world of 2D input and output. This area includes an array of computers that are color-calibrated and color-matched to inkjet printers.

2D Large-Format Printing
A wide array of computers loaded with industry-leading software programs are color-calibrated and color-matched, via ICC workflow, to large-format printers to ensure superior results. Color management training is provided by professional master printers.

2D Large-Format Scanning
Large-format, state-of-the-art scanners for scanning existing work or creating collages. Input from these scanners can be used as a basis for 2D large-format prints.

3D
State-of-the-art 3D data-capture systems, modeling packages, and rapid-prototyping equipment. Attendees can generate 3D digital objects either by modeling in the latest version of various full-featured software packages or by using 3D data-capture devices to scan actual objects.

3D Data Capture
Bring in an object to be scanned, scan yourself, or sculpt an object out of clay and scan that. Objects are, in effect, measured or imaged three dimensionally and then those measurements or images are translated into points that are placed in a virtual 3D space. On the computer, the points become vertices that can be connected by segments to create a "skin" or "surface" of triangles and squares that are the digital equivalent of the surface of the object that was scanned. Some scanning processes result in a very detailed digital model, while others capture only the primary features of objects. Once an object has been scanned and converted into a digital model (usually an .stl file), that file can be imported into 3D modeling applications to enable further cleanup or manipulation (cut, scaled, twisted, bent, combined with other models, etc.). Then the model can be output to a rapid prototyping machine to again become a physical 3D object, animated with 3D animation software, or shaded, textured, rendered, and printed as a 2D image.

3D Modeling
Almost any form, real or imagined, can be generated using 3D modeling applications. The excitement is in the realization that you are actually drawing in three dimensions, where objects (or whole environments) can be viewed from any point of view and quickly moved, scaled, or more dramatically altered for more dynamic and intuitive creative exploration. A completed model can be output to a rapid-prototyping machine, animated with 3D animation software, or shaded, textured, rendered, and printed as a 2D image.

Rapid Prototyping (RP)
Any CAD model that has wall thickness or that is "solid" can be prototyped. The computer model is first digitally "sliced" into very thin layers (usually a few thousands of an inch). The RP machine then uses those slices to physically build the object layer by layer. Some machines build by sintering (melting) granules of plastic or hardening layers of epoxy, while others extrude thin layers of thermal plastic or laminate layers of paper. Each process and material has its own interesting advantages and disadvantages, and most allow hands-on "bench work" for final finishing of pieces. RP was primarily developed and used for aerospace, automotive, toy, and medical applications, but it has gained wide acceptance in the arts, architecture, jewelry, and other areas. The distinct advantage of rapid prototyping or layered manufacture over all of the other automated processes is that it fabricates additively. This is a simple yet profound difference. Undercuts, convolutions of form, intricate geometry -- all are easily accomplished in an additive process.

Animation
Attendees are introduced to various off-the shelf commercial animation software packages, general interface, workflow, and creation tools via hands-on sessions and interacting with the Guerilla Studio volunteers. Topics include modeling, texturing, lighting, and application of the basic principles of animation. Attendees can go through the steps of generating key-frame and procedural animation, and full body and facial motion capture to bring creatures, characters, props, and other scene elements to life.

Virtual Reality
BLUIsculpt, a system for immersive display configured for 3D solid modeling developed at the Arctic Region Supercomputing Center, is an interactive virtual reality application that permits a user to freely sketch voxels inside a 10-foot volume of space for output as physical objects. It connects the imagination to physical form. The interface presents the user with real-time feedback in the form of surfaces. A file representing the surface can be saved in rapid-protyping format and then produced.

Generating a solid by rapid prototyping completes the cycle of perception and imagination that starts in the physical world, proceeds through vision, thought, imagination, and the dance of drawing to finally arrive at tangible sculpture. The enterprise is based on the premise that symbolic representation derives from perception, imagination, and thought.
