Hi, I am Zhihao, currently a first year Ph.D. student at The University of Tokyo (UTokyo), advised by Prof. Naoto Yokoya (at Sugiyama-Yokoya-Ishida Lab). I am also affliated with RIKEN AIP as a junior research assistant. My interest lies at the intersection of computer graphics, geometry modeling and 3D vision.

This is my implementation of the parametric L-system algorithm for 3D tree modeling. One can use it to automatically produce different types of trees by adjusting the structural rules and procedural parameters.

This is the old version software of our recent Paper DeepTreeSketch. This tool enables users to easily design 3D tree models from 2D sketches. The use of this software doesn't require any configuration in Windows 10+ operating systems since it is based on only computer graphics algorithms without using deep neural networks. Please feel free to have a try!

This project is to pysically simulate the fluid deformation based on the Affine Particle-In-Cell method (APIC), which is originally introduced by a SIGGRAPH paper [Jiang et al.]. The algorithm is basically implemented in C++, while a few parts of numerical computation are achieved in Python and CUDA. The images are all rendered offine using the basic Ray-Tracing with OpenGL and C++.

This is an open-source software that I implemened for visualizing the 3D corals and interactively obtaining its rugosity. This tool has been already used by a few ocean biologists in their researches. It is implemented using C++ and OpenGL.

I tried to reproduce a journal paper published in the Visual Computer [Gai et al.] during my undergraduate time. It translates the input images into the popular low-polygon fashion style.

I implemented a very powerful 3D modeling engine for plants by using a grammar-based growing algorithm, which supports parameter control and algebra expression for designing various plant species.

I implemented several NPR effects with OpenGL, for example, the pencil drawing and oil painter etc., with reference to a popular book titled 'real-time rendering'.

I tried to develope a simple but nice looking Minecraft using OpenGL within only two days. It supports infinite terrain, shadow mappimg, dynamic water as well as diverse customizable materials. The scene can be rendered very efficiently (around 150 FPS). The caves were generated procedurally by using 3D simplex noise algorithm. Moreover, the players can freely construct their own buildings.

Thank Jon Barron for this nice template!
