Frequently Asked Questions · /category/3d-spatial

Can I run 3D generation on a consumer GPU?

Yes — modern open-weight models like IDOL 3D-DiT require around 7.2GB VRAM and run comfortably on RTX 3060/4060 GPUs.

What format do open 3D Gaussian models output?

They generate dense 3D Gaussian Splat (.ply) files compatible with WebXR, Unity, Unreal Engine, and web splat viewers.
