Generalizable and Relightable Gaussian Splatting for Human Novel View Synthesis
Contributions: โข We propose GRGS, a generalizable and relightable 3D Gaussian framework that projects geometry, material, and illumination cues from multi-view 2D observations onto 3D Gaussian attributes in a feed-forward manner, enabling realistic and robust novel view synthesis of unseen data under novel lighting conditions.
โข We present a Lighting-aware Geometry Refinement module trained on synthetically relit multi-view data to estimate lighting-invariant depth and surface normals, effectively mitigating geometry errors caused by uneven illumination.
โข We design a Physically Grounded Neural Rendering module that combines physics-based rendering with neural rendering, supporting high-quality shading phenomena synthesis while avoiding the computational overhead of explicit ray tracing.
