Rethinking 3D Shape Generation: Diffusion over Superquadrics

ICML 2026poster

Diffusion models have advanced 3D shape generation, yet most methods still denoise in high-cardinality spaces (e.g., voxel/SDF grids, meshes, or point clouds), which is computationally and memory intensive and makes it difficult to scale in terms of both higher resolution and stronger controllabilit…

Learning-Free Grasping of Unknown Objects Using Hidden Superquadrics

RSS 2023poster

Robotic grasping is an essential and fundamental task and has been studied extensively over the past several decades. Traditional work analyzes physical models of the objects and computes force-closure grasps. Such methods require pre-knowledge of the complete 3D model of an object, which can be har…
