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 Paper (PDF) Additional materials: [ComputerGraphicsWorldArticle.pdf], [PaintTweenWorkingSets.tgz], [mainVideo.mov], [PaintTweenDistro.tgz], [additionalResults.mov] Available in the proceedings of SIGGRAPH 2013.

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 Paper (PDF) Video Video SIGGRAPH 2022 |

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 Paper (PDF) SIGGRAPH Talks 2023 |
