Key point
Microsoft unveiled **TRELLIS.2**, supporting high-resolution image-to-3D generation.
Details
TRELLIS.2 is a 4B parameter image-to-3D generation model designed to generate 3D assets with complex topology and sharp geometry.
Its core component is a field-free sparse voxel structure called O-Voxel, which is used to reconstruct and generate arbitrary 3D assets.
Key features are as follows.
- Generates 3D assets at up to 1536³ resolution
- Supports PBR material
- Native 3D VAE-based design with 16× spatial compression
- Open-source code, paper, and live demo provided
The released materials include an arXiv paper, GitHub code, and a Hugging Face Spaces demo.
