Qixin Liang

I received my PhD from HKU. I am interested in physics simulation, computational mechanics, and physical AI, with a focus on applying these techniques to real-world applications. I have some industry experience in data-driven multi-physics simulation and real2sim2real for robotics.

We propose a graph-neural-network-based framework and a cloth motion capture pipeline for real-time prediction of real-world cloth deformation.

SA2025 Modeling and Simulating Origami Structures using Bilinear Solid-Shell Element
Qixin Liang
SIGGRAPH Asia, 2025
paper

We propose a novel computational framework for modeling and simulating origami structures using bilinear solid-shell elements.

EG2025 Corotational Hinge-based Thin Plates/Shells
Qixin Liang
Eurographics, 2025
paper / code / video

We present six thin plate/shell models, all featuring constant bending energy Hessians, which offer significant benefits for implicit simulations using thin plate/shell models. In the source code repository libThinPlateShells, we provide 13 different bending formulations for researchers and practitioners.

SCA2024 Smoothed-Hinge Model for Cloth Simulation
Qixin Liang
ACM SIGGRAPH/Eurographics Symposium on Computer Animation (SCA), 2024
paper / poster

We present a computational model in which the membrane model effectively mitigates the sharp creasing artifact in cloth simulation, while incorporating an efficient bending model.
