Stylizing Animation By Example

Pierre Benard, Forrester Cole, Michael Kass, Igor Mordatch, James Hegarty, Martin Sebastian Senn, Kurt Fleischer, Davide Pesare, Katherine Breeden
April 2013

Skilled artists, using traditional media or modern computer painting tools, can create a variety of expressive styles that are very appealing in still images, but have been unsuitable for animation. The key difficulty is that existing techniques lack adequate temporal coherence to animate these styles effectively. Here we augment the ... more

Character Articulation through Profile Curves

Fernando de Goes, William Sheffler, Kurt Fleischer
05 2022

Computer animation relies heavily on rigging setups that articulate character surfaces through a broad range of poses. Although many deformation strategies have been proposed over the years, constructing character rigs is still a cumbersome process that involves repetitive authoring of point weights and corrective sculpts with limited and indirect shaping ... more

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

Duc Nguyen, Jeremie Talbot, William Sheffler, Mark Hessler, Kurt Fleischer, Fernando de Goes
May 2023

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 ... more

CurveCrafter: A System for Animated Curve Manipulation

Nora S Willett, Kurt Fleischer, Haldean Brown, Ilene L E, Mark Meyer
September 2023

Linework on 3D animated characters is an important aspect of stylized looks for films. We present CurveCrafter, a system allowing animators to create new lines on 3D models and to edit the shape and opacity of silhouette curves. Our tools allow users to draw, re-draw, erase, edit and retime user ... more

Stylizing Ribbons: Computing Surface Contours with Temporally Coherent Orientations

Nora S Willett, Fernando de Goes, Kurt Fleischer, Mark Meyer, Chris Burrows
September 2023

Line work is a core element for the stylization of computer animations used by recent shows. However, existing stylization tech- niques are limited to edge treatments based on brush strokes or textures applied solely on top of curves. In this work, we propose new stylization effects by offering artists direct ... more
