Multi-view Inverse Rendering for Large-scale Real-world Indoor Scenes. (arXiv:2211.10206v1 [cs.CV])

We present a multi-view inverse rendering method for large-scale real-world
indoor scenes that reconstructs global illumination and physically-reasonable
SVBRDFs. Unlike previous representations, where the global illumination of
large scenes is simplified as multiple environment maps, we propose a compact
representation called Texture-based Lighting (TBL). It consists of 3D meshs and
HDR textures, and efficiently models direct and infinite-bounce indirect
lighting of the entire large scene. Based on TBL, we further propose a hybrid
lighting representation with precomputed irradiance, which significantly …
