Liangchao Xu (许梁超)

I am a senior student at the School of Intelligent Software and Engineering, Nanjing University. I am very fortunate to be advised by Prof. Yao Yao at the 3D Vision Lab, School of Intelligence Science and Technology, Nanjing University. I also work closely with Prof. Yuan Liu from HKUST. Currently, I am a research intern with Prof. Yuxiong Wang at the University of Illinois Urbana-Champaign (UIUC). My research primarily focuses on 3D reconstruction and 3D generation.

My research focuses on 3D vision, including 3D reconstruction and 3D generation. I aim to enable highly usable 3D interaction and controllable 3D content generation.

By introducing GauUpdate, we enable fast and consistent insertion of new objects into existing 3D Gaussian fields by relighting them with inverse rendering for appearance alignment across varying lighting conditions.
