Rethinking 3D Shape Generation: Diffusion over Superquadrics

Zhiyang Liu, Wanze Li, Yuwei Wu +4

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 computation…

Marching-Primitives: Shape Abstraction from Signed Distance Function

Weixiao Liu, Yuwei Wu, Sipu Ruan +1

Representing complex objects with basic geometric primitives has long been a topic in computer vision. Primitive-based representations have the merits of compactness and computatio…
