The ACM SIGGRAPH Pioneers Group is proud to present David Em, one of the most influential artists in computer graphics, as the evening speaker for this year's Pioneers Reception. The reception will take place on the evening of Tuesday, August 1, at the SIGGRAPH 2017 conference.

David Em pioneered artistic collaboration of computer graphics, including beta testing of the first digital paint systems. At the Pioneers Reception, he will present a visual report on his insights into the history and future of computer graphics collaboration. He will be joined by special guest James Blinn.

Em created digital paintings at the Xerox Palo Alto Research Center (Xerox PARC) in 1975 with Dick Shoup's SuperPaint, the first video frame buffer paint system. In 1976, he made an articulated 3D digital insect at Information International, Inc. (III) that could walk, jump, and fly, one of the first 3D characters created by a fine artist. Em helped pioneer navigable virtual worlds with James Blinn at NASA’s Jet Propulsion Laboratory (JPL), where he was Artist in Residence from 1977 to 1984. He has also created digital art at the California Institute of Technology (1985 – 1988), and Apple Computer (1991).

The 2017 SIGGRAPH Pioneers Reception will take place on Tuesday, August 1st, from 6:00 p.m. to 8:00 p.m. In the Gold Ballroom, Salon 2; at the JW Marriott Los Angeles L.A. Live. The hotel is near the Los Angeles convention center. Light appetizers will be served, and drinks will be available. The reception is exclusive to active members of the ACM SIGGRAPH Computer Graphics Pioneers Group. Any person with 20 years of experience or more, in some aspect of computer graphics and/or interactive techniques is eligible to become a member. The cost for a non-ACM SIGGRAPH member to become an ACM SIGGRAPH CG Pioneer is $47, which includes ACM SIGGRAPH membership. New members can join online. The cost to upgrade an existing ACM SIGGRAPH membership to Pioneer level is $5, and can be done by calling ACM Help at 1-800-342-6626 or by emailing acmhelp@acm.org.

SIGGRAPH Asia 2017 has announced that Michael Cohen, Director of the Computational Photography Group at Facebook, will be a keynote speaker at the conference this November in Bangkok, Thailand.

In addition to his position at Facebook, Michael is an affiliate professor at the University of Washington. He arrived at Facebook after two decades at Microsoft Research, and has previously served on the faculties at Princeton and Cornell Universities. The Computational Photography Team at Facebook was formed in 2015 to build new ways to share photos and videos on the social media platform, including allowing Facebook users to share 3D videos and virtual reality videos to their profiles.

Michael is also a longtime ACM SIGGRAPH volunteer, and plays a key role in the organization: leading the prestigious awards program at the SIGGRAPH conference each year.

This year marks the first time SIGGRAPH Asia will be hosted in Thailand. With strong support from the ACM SIGGRAPH Bangkok Chapter and the local government, SIGGRAPH Asia expects the event to draw more than 7,000 industry professionals from the region and around the globe.

Along with Michael, Albert Yu-Min Lin, Award Winning National Geographic Explorer and Co-Founder & Chief Science Officer at Planet3, has been announced as a SIGGRAPH Asia 2017 keynote speaker.

The conference will take place from November 27 to 30, 2017. Visit the SIGGRAPH Asia 2017 website for more information.

Towards the end of Jon Watts’ "Spider-Man: Homecoming," the newest instalment of the Spider-Man franchise and now part of Marvel’s larger cinematic universe, Peter Parker (Tom Holland) makes a bold choice to try and thwart the efforts of Adrian Toomes (Michael Keaton), who is hell-bent on stealing Avengers weaponry from a plane — mid-flight — as it leaves New York.

Parker first attempts to stop Toomes at a warehouse, then on an Avengers plane, and finally when the plane crashes on a beach — each of these sequences featured visual effects from Sony Pictures Imageworks. Artists based in Los Angeles and Vancouver made use of a digital Parker in his home-made ‘Spider-Man’ garb and Toomes in his CG winged ‘Vulture’ suit. We found out more from Imageworks visual effects supervisor Theo Bialek.

Artists based in Los Angeles and Vancouver made use of a digital Parker in his home-made ‘Spider-Man’ garb and Toomes in his CG winged ‘Vulture’ suit. We found out more from Imageworks visual effects supervisor Theo Bialek.

Wings Versus the Warehouse

In the warehouse, Toomes turns his wings against Parker by sending it to knock down the surrounding concrete columns. To help with animation of their digital Parker trying to jump clear of the wings, Imageworks looked to some rather interesting video footage.

“We found references of people who like to jump over moving cars — apparently that’s a thing,” notes Bialek. “These guys just stand there and then these sports car, generally low, low sports cars, go racing towards them in excess of 70, 80 miles an hour, and these people just jump straight up in the air, and they’d leap over these cars.”

“We even looked at reference of this cheese rolling contest where they roll cheese down a hill in England,” adds Bialek. “That was for when we had a shot in the beach battle where someone is rolling off the plane, and we would look at that for reference for having someone tumble. Tom actually had reference of himself jumping on trampolines, and doing like jumping side flips, and back flips, too.”

In the warehouse battle, and in a few other sequences Imageworks was responsible for, Parker wears a loose version of a suit he has hand-made. It’s a far cry from the form fitting tech-fitted version that Tony Stark had made for Parker, but it does the job. For the visual effects team, it was still a challenging exercise to realize, due to its extra drawstrings, floppy hood and need to simulate secondary cloth motion.

“We built the costume in Marvellous Designer,” explains Bialek. “It forces the modeller to construct the cloth physically accurately. So all the panels and stitching lines are all in the right places that a real costume would be — there were no cheats done in that sense.”

Flying High

The plane sequence began with concept art and previs. The action was to be incredibly frenetic, which means much of the battle would be produced in CG. Motion capture shoots for Spider-Man using stand-in shells for the plane and other set pieces for Imageworks’ sequences gave the studio much-needed animation reference. They also relied on its own motion capture produced back at the office with an XBox Kinect set-up.

“I’d say probably 30 per cent of the character animation we did, we ended up using mocap that we shot or from our own low tech mocap sessions,” states Bialek. “And even the stuff we didn’t necessarily use, we used for reference. It was really key to having the animators kind of lock into Tom and how he acts.”

“We’d even look at the off-takes,” continues Bialek. “Like, when he kind of trips, or something, and you obviously can’t use that, but you see how he catches himself, and how he reestablishes his balance. We were trying to infuse that into the performance whenever we could.”

Vulture was also a digital creation, with a model shared from a different vendor. The challenge in animating this character came from the 32 foot wingspan, and the sheer weight of the wings. “We’re always trying to come up with clever little ideas on how to force that kind of resistance,” says Bialek. “Michael Keaton’s character isn’t really a superhero, so he doesn’t move with lightning speed, he moves like a normal person would, and that was the idea.”

The Avengers plane that Vulture attempts to take over is fitting with a cloaking system. It had to be somewhat grounded in reality, so Imageworks referenced a real-world system made by BAE Systems for tanks and armoured vehicles.

“They use these tiles that can basically emulate a heat signature with any vehicle, or any object,” says Bialek. “In fact, they can put cameras on these tanks and they’ll see what you would see behind the tank, and then create kind of a low resolution heat signature on the side of the tank. So we looked at that, and how they constructed those tiles, and put them on the surfaces of the plane.”

Beach Battle

The plane ultimately crashes on a beach near Coney Island, and Spider-Man and Vulture stand off once more amid a fiery wreckage. “The shot the fight on this giant sandbox — it was huge,” says Bialek. “And they had pieces of plane wreckage, all smashed up, that they used. And they had a bunch of debris there, and flame bars. We scanned the beach set and made a digital version and did extensions.”

One aspect of the film Bialek particularly enjoyed — and that has been quite common on recent Marvel and Sony films — is the collaboration between vendors. Different visual effects studios would tackle different CG builds, share assets and sometimes even work on the same sequences.

“It is a very collaborative effort with them. And they’re also not looking for a vendor that’s just going to do what they’re told. They want somebody who’s also going bring stuff to the table and show them.”
