Animated 3DGS Avatars in Diverse Scenes with Consistent Lighting and Shadows
Contributions: โข Deep Gaussian Shadow Maps (DGSM): A volumetric deep-shadow formulation for Gaussian splats, featuring closed-form light accumulation and efficient octahedral-atlas storage for fast sampling.
โข Fast avatar relighting via SH HDRI probes: A per-frame, per-Gaussian SH transfer that approximates local environment lighting without explicit BRDFs or meshing.
โข Coherent lighting for dynamic 3DGS scenes: An integrated pipeline that enables avatars and inserted objects to cast shadows and exhibit scene-matched lighting, validated across ScanNet++, DL3DV, and SuperSplat scenes with AvatarX/ActorsHQ avatars.
