Project Page | GitHub | arXiv

BRDFusion is a unified framework that combines physics-based inverse rendering with generative modeling for high-quality urban scene relighting. It decomposes urban videos into geometry, materials, and HDR lighting, enabling applications such as novel-view rendering, night simulation, and dynamic object insertion/editing.

By combining these two complementary approaches, BRDFusion recovers explicit, consistent scene properties with physical modeling and alleviates optimization ambiguity with generative priors. During forward rendering, the physical model provides controllable rendering from the scene configuration, and the generative model denoises and fixes artifacts.
