Image to 3DWhat is TRELLIS.2? Independent service, not Microsoft
TRELLIS.2 – AI Image-to-3D Model Generator
TRELLIS.2 is an independent image-to-3D generator: upload one photo and get a textured 3D model. The 4-billion-parameter workflow produces O-Voxel geometry, PBR materials, and a GLB starting asset you can inspect, clean, and adapt.

Start with a clean single-object image
Users who upload a clear front or three-quarter view get better mesh shape, texture detail, and fewer failed runs.

Everything inside trellis-2 supports image-to-3D conversion with reviewable GLB starting assets.
Trellis 2 4B Parameters
TRELLIS.2 is powered by a 4 billion parameter flow-matching transformer for superior image-to-3D generation quality.
TRELLIS.2 O-Voxel Structure
Trellis-2 uses novel field-free sparse voxel representation (O-Voxel) for efficient 3D encoding with arbitrary topology support.
Trellis.2 Up to 1536³ Resolution
TRELLIS.2 generates 3D assets at resolutions up to 1536³ with 16× spatial compression for detailed geometry.
TRELLIS.2 PBR Materials
Trellis 2 produces full PBR material sets including base color, metallic, roughness, and alpha for transparency.
TRELLIS.2 Managed Generation
Generation runs through a managed provider queue. Completion time varies with resolution, image complexity, and provider load.
TRELLIS.2 GLB Export
trellis 2 exports directly to GLB format for inspection and downstream editing in Blender, Unity, Unreal, and web 3D viewers.
Why trellis-2 (TRELLIS.2) leads AI image-to-3D generation
TRELLIS.2 uses a novel field-free sparse voxel structure (O-Voxel) and flow-matching transformers to convert single images into detailed 3D models with PBR materials. trellis-2 handles arbitrary topology, thin geometry, and transparent objects.
Trellis 2 Image-to-3D Conversion
TRELLIS.2 converts a single image into a 3D model with geometry and textures. Upload product photos, artwork, or concepts to trellis-2 and download a GLB starting asset for review and cleanup.
TRELLIS.2 High Resolution Output
Trellis 2 produces 3D assets at up to 1536³ voxel resolution. TRELLIS.2 uses 16× spatial compression in its VAE for compact latent representations while maintaining exceptional detail in the final 3D output.
Trellis-2 PBR Textures
TRELLIS.2 generates physically-based rendering (PBR) materials including base color, metallic, roughness, and alpha channels. Review and adapt the GLB output for your game engine, VR application, or professional 3D pipeline.
Trellis.2 GLB Export
TRELLIS.2 exports 3D models in GLB format compatible with all major 3D software. Download your trellis-2 generated assets and import directly into Blender, Unity, Unreal Engine, or any GLB-compatible application.
trellis-2 leads open-source image-to-3D AI
trellis-2.com delivers downloadable GLB starting assets to inspect and adapt for games, VR, and 3D printing.

Create 3D models with trellis-2 (TRELLIS.2) in 3 simple steps
Upload an image, let trellis-2 process it, and download your 3D model. The entire trellis 2 workflow happens at trellis-2.com.
1
Step 1: Upload your image to TRELLIS.2
Upload any image to trellis-2 - product photos, artwork, concept designs, or real-world objects. TRELLIS.2 works best with clear subject images with alpha-masked foregrounds at trellis-2.com.
2
Step 2: Trellis 2 generates your 3D model
TRELLIS.2 uses its 4B-parameter flow-matching transformer to convert your image into a 3D model. trellis.2 processes geometry and textures simultaneously using the O-Voxel representation.
3
Step 3: Download your trellis-2 3D asset
Download your TRELLIS.2 model in GLB format with PBR textures. Inspect, clean, and optimize the starting asset in your 3D software before game-engine, VR/AR, or 3D-printing use.
