Trellis 2 — Image to 3D with Clean, Predictable Topology
Clean-Topology 3D Models from One Image
Trellis 2 is Microsoft's image-to-3D model, built to turn a single picture into a well-structured GLB mesh. Upload an image of an object or character and TRELLIS reconstructs both shape and texture in one pass, with a focus on clean topology that imports predictably and textures cleanly. You decide the output resolution — 512, 1024, or 1536 — trading speed for fidelity, and the result renders as a standard GLB ready for the web, game engines, and AR. Preview it interactively on this page: orbit, zoom, and check the form from every angle before downloading. It's a fast, reliable way to go from a flat image to a 3D asset you can actually work with.
TRELLIS approaches 3D generation as a structured pipeline rather than a single black box, which is why the meshes tend to come out tidy. Clean topology matters more than raw triangle count for most real work: it's what lets a model deform sensibly when rigged, subdivide without artifacts, and accept new textures without stretching. Trellis 2 prioritizes exactly that, so the assets are friendlier to edit in Blender, Maya, or your engine of choice.
Resolution is the main quality lever. The 512 setting is the fastest and cheapest, ideal for quick iteration and previews; 1024 is the balanced default for most assets; and 1536 pushes for maximum fidelity when you need crisp surface detail. Texture size scales alongside the geometry so the materials stay sharp at higher settings. Because every output is a standard GLB, it drops straight into three.js, Babylon.js, Unreal, Unity, and any glTF viewer.
The process stays simple: one clear image with the subject isolated from its background gives the best reconstruction. Pick a resolution, generate, and inspect the result in the built-in viewer. When you're happy, download the GLB and move on — and find every generation saved in your dashboard gallery for later.
How to Generate a 3D Model with Trellis 2
Upload an Image
Choose a single, clear image with your subject separated from the background. An object or character on a plain backdrop gives the cleanest reconstruction.
Choose Resolution
Pick 512 for fast iteration, 1024 for a balanced result, or 1536 for maximum fidelity. Higher resolutions take a little longer and cost a few more credits.
Generate & Download
Click Generate, then orbit and zoom the model in the interactive viewer. Download the GLB — every generation is also saved to your dashboard gallery.

Frequently Asked Questions About Trellis 2
What does the resolution setting change?
Resolution controls the fidelity of the generated geometry and texture. 512 is the fastest and cheapest option for quick iteration, 1024 is a balanced default for most assets, and 1536 produces the most detailed result. Higher resolutions take a little longer and cost a few more credits.
What file format does Trellis 2 output?
Trellis 2 outputs a standard GLB file — the glTF binary format used across the web, game engines, and AR. It loads directly in three.js, Babylon.js, Unreal, Unity, and any glTF-compatible viewer, including the interactive preview on this page.
Why does clean topology matter?
Clean topology means the mesh is structured in a way that's easy to work with: it deforms sensibly when rigged for animation, subdivides without artifacts, and accepts new textures without stretching. For most real production work this matters more than raw triangle count, and it's a core focus of TRELLIS.
How long does generation take?
Usually one to two minutes depending on the resolution you choose. Generation runs asynchronously — progress is shown on the page and the finished model is saved to your dashboard gallery, so you can navigate away and return.
Can I use the models commercially?
Yes. Models generated with Trellis 2 support commercial use, including games, products, client work, and monetized content. Download your file within 7 days — gallery media is cleaned up after that window.
How is this different from Hunyuan 3D V3.1?
Trellis 2 focuses on clean, edit-friendly topology with explicit resolution and texture-size control, and outputs GLB. Hunyuan 3D V3.1 emphasizes high-fidelity geometry with optional PBR materials and both GLB and OBJ export. Run the same image through both and keep whichever result best fits your workflow.
