💩 Zhihao Liu

Hi, I’m a PhD student at Department of Complexity Science and Engineering, The University of Tokyo (UTokyo), advised by Prof. Naoto Yokoya (in Machine Learning and Statistical Data Analysis Lab). I am also affliated with RIKEN AIP as a junior research assistant. Prior to that, I worked at Tencent (腾讯) as a graphics researcher. My interest lies at the intersection of computer graphics, geometry modeling and 3D vision. Here is my full CV.

The above are some of my featured free software (not papers), built purely on graphics algorithms in either C++ or C#.
Because they don't use AI, you can directly run on Windows PCs without any configuration. I am so proud of them and some have been used to make datasets for my own research and other SIGGRAPH/CVPR papers from external labs (e.g., TreePartNet).
🠆 See [Projects] for more toolkits I developed. Feel free to download and explore.
