OctGPT: Octree-based Multiscale Autoregressive Models for 3D Shape Generation
SessionInvited: Posters
DescriptionOctGPT is a novel multiscale autoregressive model for 3D shape generation. It introduces hierarchical serialized octree representation, octree-based transformer with 3D RoPE and token-parallel generation schemes. OctGPT significantly accelerates convergence, achieves performance rivaling or surpassing state-of-the-art diffusion models, and supports text/sketch/image-conditioned generation and scene-level synthesis.
