Hi3D 1.0 · ZeroGPU

Unofficial community demo of Hi3D v1.0, high-resolution 3D geometry refinement built on Sparc3D. It uses the official weights and inference code. Image → coarse mesh (Hunyuan3D-2 mini turbo, the official example coarse stage) → Hi3D refinement at 512³ / 1024³ / 1536³. The output is geometry only: no textures, recentered and normalized to unit radius.
