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…
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…
OctaOctree Neural Radiosity for Real-time Glossy Material Rendering
Jierui Ren, Haojie Jin, Bo Pang +4
Modeling high-frequency outgoing radiance distributions remains a fundamental challenge in global illumination, especially for glossy and specular materials. Existing neural-based…
Vertex Features for Neural Global Illumination
Rui Su, Honghao Dong, Haojie Jin +3
Recent research on learnable neural representations has been widely adopted in the field of 3D scene reconstruction and neural rendering applications. However, traditional feature…
Real-time Global Illumination for Dynamic 3D Gaussian Scenes
Chenxiao Hu, Meng Gai, Guoping Wang +1
We present a real-time global illumination approach along with a pipeline for dynamic 3D Gaussian models and meshes. Building on a formulated surface light transport model for 3D G…
SonicRadiation: A Hybrid Numerical Solution for Sound Radiation without Ghost Cells
Xutong Jin, Fei Zhu, Guoping Wang +1
Interactive synthesis of physical sound effects is crucial in digital media production. Sound radiation simulation, a key component of physically based sound synthesis, has posed c…
