Creating Curved-based Garments with Custom Weave Patterns

Sun, Aug 6 3:07 PM – 3:30 PM PST
Room 515 B

In Disney's Strange World, the handmade quality of the costumes was a creative need for representing the technological limits of the setting, Avalonia.

Splat Developing a ‘Strange’ Shader

Sun, Aug 6 3:45 PM – 4:07 PM PST
Room 515 B

In Walt Disney Animation Studios’ Strange World, the character Splat presented unique artistic requirements posing computational challenges.

Progressive Null-Tracking for Volumetric Rendering

Tue, Aug 8 2:42 PM – 2:52 PM PST
Room 502 A/B

In production settings where procedurally generated participating media is common, many unbiased null-collision-based rendering algorithms result in either impractical amounts of noise or excessive cost due to having unknown bounding extinctions. We introduce a consistent progressive approach which makes null-collision-based techniques resilient to non-bounding extinctions while remaining performant.

100 Years of Art + Technology at Walt Disney Animation Studios

Tue, Aug 8 3:30 PM – 4:30 PM PST
Room 407

For nearly 100 years, Walt Disney Animation Studios has been a place of creativity and innovation. From the first cartoon with synchronized sound to the multiplane camera, Fantasound, Xerography, the Computer Animation Production System (CAPS), and implementing the evolving artistry and sensibility of both hand-drawn and computer-generated imagery, Disney Animation has been a combination of technology and art. Marlon West, a thirty-year veteran of the studio and VFX supervisor of the upcoming Disney+ series, Iwájú, will discuss his own journey, the studio’s journey through many technical advances, and look at how the past inspires and drives the future.  

Swoop: Animating Characters Along a Path

Sum-of-squares Collision Detection for Curved Shapes and Paths

Thu, Aug 10 2:44 PM – 2:54 PM PST
