3D Gaussian Inverse Rendering with Approximated Global Illumination
Zirui Wu, Jianteng Chen, Laijian Li, Shaoteng Wu, Zhikai Zhu, Kang Xu, Martin R. Oswald, and Jie Song. arxiv, 2025 Project Page / arXiv / GitHub We propose a real-time approximated global illumination method for 3D Gaussian inverse rendering. The key idea is to leverage indirect emissors in the screen space to approximate the global illumination effect. |

MARS: An Instance-aware, Modular and Realistic Simulator for Autonomous Driving
Zirui Wu, Tianyu Liu, Liyi Luo, Zhide Zhong, Jianteng Chen, Hongmin Xiao, Chao Hou, Haozhe Lou, Yuantao Chen, Runyi Yang, Yuxin Huang, Xiaoyu Ye, Zike Yan, Yongliang Shi, Yiyi Liao, and Hao Zhao CICAI, 2023 (Best Paper Runner-up Award) Project Page / arXiv / GitHub We propose an autonomous driving simulator based upon neural radiance fields (NeRFs). Compared with existing works, ours has three notable features: (1) Instance-aware. (2) Modular. (3) Realistic. Our simulator achieves state-of-the-art photorealism results given the best module selection. Our simulator will be open-sourced while most of our counterparts are not. |

LATITUDE: Robotic Global Localization with Truncated Dynamic Low-pass Filter in City-scale NeRF
Zhenxin Zhu, Yuantao Chen, Zirui Wu, Chao Hou, Yongliang Shi, Chuxuan Li, Pengfei Li, Hao Zhao, and Guyue Zhou. ICRA, 2023 arXiv / GitHub We propose a two-stage pipeline for global localization in a city-scale neural map. |

OmniNeRF: Hybriding Omnidirectional Distance and Radiance fields for Neural Surface Reconstruction
Zirui Wu, Jiaming Shen, Bolin Song, Yi Xu CMSDA, 2022 arXiv / GitHub We solve two systematic errors in classical distance-radiance field by utilizing omnidirectional distance field. |
