Xifeng Gao


Principal Researcher @ Lightspeed Studios at Tencent | xifgao@global.tencent.com

I have wide research interests in fields related to Geometry Computing, such as Computer Graphics, Fabrication, and Robotics.

My current focus is on designing gaming oriented geometry processing and content generation algorithms, using techniques in differentiable/neural rendering, computational geometry, and numerical analysis.
We have multiple R&D intern openings for working on 3D static/dynamic content generation and processing problems. If interested, please let me know.
