Shaping the Elements: Curvenet Animation Controls in Pixar's Elemental

Duc Nguyen, Jeremie Talbot, William Sheffler, Mark Hessler, Kurt Fleischer, Fernando de Goes

Abstract:

We present a new shaping rig for authoring layers of animation control that facilitate surface editing in shot work. Our approach expands the curvenet rigging technology [de Goes et al. 2022] by introducing new tools that auto-generate a surface-aligned direct manipulator per curvenet knot. As a result, we obtain a mapping from animation controls into curvenet adjustments relative to the deforming surface with minimal setup. We showcase our curvenet shaping rig using results from Pixar's feature film Elemental (2023).
