TRELLIS.2: Microsoft Releases 3D Generative Model with O-Voxel Structure

TRELLIS.2 is an open-source 4B-parameter 3D generative model by Microsoft designed for high-fidelity image-to-3D generation. Using a field-free sparse voxel structure named O-Voxel and Diffusion Transformers, it handles arbitrary topologies, sharp geometry, and complete PBR materials.
