Luce: Relightable Gaussians — a multimodal Gaussian voxel representation for 3D asset generation
Luce is a proposed 3D representation that unifies geometry and physically based rendering (PBR) materials by encoding dedicated Gaussian primitives per modality inside a voxelized multimodal Gaussian cloud. A variational autoencoder compresses this representation into a unified material-aware latent space to support relightable image-to-3D asset generation and integration with standard rendering pipelines.
