Happy to share that my internship project at DisneyResearch has been accepted to #SIGGRAPH2025. Will be presenting it in person next week. Come drop by :)

ScaffoldAvatar: High-Fidelity Gaussian Avatars with Patch Expressions (#SIGGRAPH) We reconstruct ultra-high fidelity photorealistic 3D avatars capable of generating realistic and high-quality animations including freckles and other fine facial details. We operate on patch-based local expression features and increase the representation capacity by synthesizing 3D Gaussians dynamically by leveraging tiny scaffold MLPs conditioned on localized expressions. We further propose a color-based densification and progressive training scheme for improved quality and faster convergence.

📢MeshPad: Interactive Sketch-Conditioned Artist-Designed Mesh Generation and Editing📢 Users can interactively design 3D models just from a sketch-based interface - check out the demo :) We break down the design process into addition with an autoregressive generator and deletion operations enabled by a classifier. To speed-up predictions, we propose a mesh-specific speculator such that users get immediate within a few seconds.

Key idea: distill reconstruction constraints from a multi-view head diffusion model to complete unobserved regions. tangjiapeng.github.io/projects/GAF/ youtu.be/QuIYTljvhyg Great work by @jiapeng_tang @davidedavoli @TobiasKirschst1 @liamschoneveld
