What is TRELLIS 3D AI?
TRELLIS 3D AI is a browser-based image to 3D service for 3D asset generation. Users upload a picture, the AI builds a model with geometry and textures, and the result can be previewed in an in-browser viewer before being downloaded in GLB, OBJ, STL, GLTF, USDZ or PLY format. A free online version is available, and the site notes it has since been upgraded and rebranded as Morfx 3D.
The tool is based on the TRELLIS approach, which uses Structured Latents (SLAT) together with pretrained vision encoders and rectified flow transformers to keep both the shape and visual detail of the source image. Beyond generation, the site describes local editing of specific regions of an asset, multi-view input, and a set of free 3D file viewers for formats such as GLB, STL, OBJ, FBX and USDZ.
Who it's for
- Game developers needing quick 3D assets
- 3D artists and designers
- AR and e-commerce creators
- 3D printing hobbyists
- Indie makers prototyping 3D content
