Signed Distance Fields Dynamic Diffuse Global Illumination [article]

Jinkai Hu, Milo Yip, G. Elias Alonso, Shihao Gu, Xiangjun Tang, Xiaogang Jin
2020 arXiv   pre-print
Global Illumination (GI) is of utmost importance in the field of photo-realistic rendering. However, its computation has always been very complex, especially diffuse GI.  ...  To overcome these limitations, we propose a novel approach of computing dynamic diffuse GI with a signed distance fields approximation of the scene and discretizing the space domain of the irradiance function  ...  amount of work for large and complex scenes.  ...
