Tianyu Huang
Final-year undergraduate @ School of Software, Tsinghua University.
My long-term research goal is twofold: on one hand, to tackle fundamental challenges in traditional theoretical and numerical frameworks of graphics and geometry; on the other, to draw inspiration from classical graphics methodologies to advance emerging domains.
I have enjoyed fruitful collaborations with Professor Feng Xu at Tsinghua University and Professor Shuang Zhao at University of Illinois Urbana-Champaign, and I am presently working with Professor Toshiya Hachisuka at University of Waterloo and Ryusuke Sugimoto at Institute of Science and Technology Austria.
7 Oct, 2025 – I will be at SIGGRAPH Asia 2025 to present my solo short paper. See you in Hong Kong!
Publications(+1 TBA)
† denotes the corresponding (or sole) author.
* denotes equal contribution.
My recent interests lie in numerical algorithms in graphics and geometry, e.g., stochastic methods for solving (boundary) integral equations.

A Caveat on Differentiating Time-Domain Wave Boundary Integral Equations
Physicists usually do not worry about the order of integration and differentiation, since in most cases the functions involved are at least C^1-continuous. However, one cannot always take this for granted. Read more.

Hemisphere Sampling or Spherical Sampling: A Small Detail of Importance Sampling the Poisson Kernel in Walk on Boundary
In WoBToolbox, there is a seemingly puzzling step when sampling this term: the author uses uniform hemisphere sampling to generate rays, and this hemisphere is not aligned with the geometric normal of the boundary. Read more.

Projects
Eric’s MagicaVoxel Shaders
Shaders for MagicaVoxel including Terrain Generator, Game of Life, Waterflow Simulator, Advanced Flood Shader etc.
This is a well-known shader project that has been used in a lot of voxel art creations.
RenderToy 2
RenderToy 2 is a PBR final project for the IIIS course Advanced Computer Graphics.
This project won the 1st place in the PBR track in the popularity vote at the end of the course.

While doing graphics research, I am also an active amateur CG artist. I like to create still images with a realistic style, especially fan art of my favorite video games.
