SIG Seminar: “Physics-based Animation at Pixar”

Pixar’s films rely heavily on physically simulated effects such as the motion of hairs, cloth, and water, to cite a few. Whereas physical accuracy is of paramount importance in engineering applications, the most important aspects of feature film productions are directability and speed. In this talk, I’ll survey our recent work in this area, including […]

SIG Seminar: “Uncertainty-Driven Geometry Reconstruction and Understanding”

Choosing suitable data representations is one of the most critical topics when installing machine learning on 3D data. This talk discusses several recent works on utilizing uncertainty as a lens to develop suitable data representations and formulations for geometry reconstruction and understanding. We will discuss both theoretical results and applications in multi-scan registration, pose estimation, […]

SIG Seminar: “A History of Crowd Simulation and Rendering at Pixar”

This talk will cover how Pixar’s crowds pipeline evolved from “A Bug’s Life” to “Onward”, and how the studio’s artists and engineers refined and re-invented their tools over the years to create memorable animated crowd scenes.  We’ll cover the progression from finite state machine control, to agent based crowd simulation, to sketch based workflows, using […]

SIG Seminar:”Differentiable Machine Learning in Deformable Simulation”

Using the digital computer to simulate dynamic behavior of elastic and soft objects is a highly desired feature in many scientific and engineering areas: in computer animation, it provides realistic effects of soft characters; in surgical simulation, it delivers vivid visual experiences to the trainee; in digital fabrication, it couples geometry design and mechanical analysis. […]
