MaterialClusterGS: Palette-Based Material Decomposition and Physically-Based Relighting with 2D Gaussian Splatting
Hao Zhang, Ang Li, Boyan Du +6
We present MaterialClusterGS, a palette-based material decomposition framework for 2D Gaussian Splatting that enables physically based relighting and material editing. Existing Gau…

PTIR-GS: Path-Traced Inverse Rendering with Global Illumination in 3D Gaussian Fields
Junke Zhu, Hao Zhang, Yutian Zhu +6
Ray tracing enables 3D Gaussian fields to serve as a representation for physically based light transport. Faithful inverse rendering requires forward rendering and backward optimiz…
