Apple's Luce generates relightable 3D assets from single images

Luce, a new 3D representation from Apple ML Research, unifies geometry and PBR materials in a voxelized multimodal Gaussian cloud, decoded from a single image via a rectified-flow transformer. On Toys4K, it improves FID by 28% over the strongest baseline and achieves a CLIP image-alignment score of 0.8519 vs. 0.8299.
