Sharp relief

Hi3DGenAlpha

Stable-X's normal-bridged pipeline. It first estimates a surface-normal map of your photo, then reconstructs the shape from those normals, which recovers crisp edges and fine relief. Geometry only, tuned for sharpness.

One of several local engines in 3D Mate. Switch per model, any time.

Hi3DGen runs fully offline on a Mac inside 3D Mate. It reads the surface normals of your photo and reconstructs geometry from them, which recovers crisp edges and fine surface detail, entirely on Apple Silicon with no cloud upload or account. It needs 16 GB of unified memory (32 GB recommended) and only about 5 GB of disk, and finishes in a few minutes at Standard on an M1 Pro. Hi3DGen produces geometry without texture and exports GLB and STL, which makes it a strong fit for 3D printing. For a textured result use TRELLIS.2 4B or TripoSG.

Made with 3D Mate. A sample result, to show the app's output.

What it is great at

  • Crisp edges and fine surface relief, brought out by reading normals first.
  • Busts, reliefs, and detailed surfaces where sharpness matters.
  • Sharp geometry from a single photo, running entirely on your Mac.

Trade-offs

  • Geometry only. It ships the sharp shape as GLB and STL, without texture.
  • Takes minutes rather than seconds, like the other detailed engines.

FAQ

Does Hi3DGen run offline on Mac?
Yes. Hi3DGen runs entirely on your Mac, fully offline and on-device. No internet connection, no cloud account, and nothing you import or generate ever leaves your machine.
Do I need an internet connection or an account to use Hi3DGen?
No. Once 3D Mate and the Hi3DGen engine are installed, everything runs locally on Apple Silicon. You can generate 3D models with Hi3DGen on a Mac that is completely offline.
