Yu Zhang (张宇)

I am a research assistant in Prof. Yin Yang 's lab at the University of Utah. Meanwhile, I am also collaborating with Prof. Chuang Gan, participating in the Genesis project.

Before joining Yin Yang's lab, I worked at MeshyAI (working with Dr. Tiantian Liu and Dr. Yuanming Hu) and Tencent Games, and interned at NetEase Games. I earned both my bachelor's and master's degrees in Computer Science and Technology from Beijing Normal University, where I was advised by Prof. Zhongke Wu.

My research interests include 3D AIGC, Computer Graphics (especially physical simulation) and Robotics etc.

I'm actively looking for PhD positions in fall 2025. Please contact me if you're interested!

    Baraff-Witkin Cloth Model with IPC Collision Handling

    An implementation of the Baraff-Witkon cloth model. Unlike the original solver, our solver is based on an optimization formulation of the cloth model, and we solve this optimization problem using Newton's method. The IPC (Incremental Potential Contact) algorithm is used to handle the collision between the cloth and the rigid body.

    Meshy - A 3D AIGC Project

    Participating in the Meshy project as a graphics R&D engineer. Meshy is a 3D AIGC project that aims to generate 3D models from the text or image prompt. My responsibilities include optimizing the generateion quality and performance of the 3D generative model, and investigating various differentiable geometric representations, etc.

    Classical Partial Differential Equations: Numerical and Exact Solutions

    Several classical linear partial differential equations, including the transport equation, Laplace's equation, the heat equation, and the wave equation, are analyzed. Their exact solutions and numerical solutions (including Eulerian methods and Monte Carlo methods) in two-dimensional space are then compared.

    A Corrected Derivation of Invertible Neo-Hookean Model

    In this project, we implement several different invertible constitutive models. Additionally, we correct the derivation of the invertible neo-hookean model, which is presented in the SIGGRAPH course 'Dynamic Deformables: Implementation and Production Practicalities'.

    Github Article

    High-Performance PBD Physics Engine

    This project aims to develop a high-performance PBD (position-based dynamics) physics engine, which is similar to Houdini Vellum. The engine supports a series of materials' simulation: rigid body, soft body, fluid, cloth, granular material, etc. We achieve a 60 FPS's 240k particles fluid simulation, and the simulation can be extended to a large-scale scene (there are 20 million particles in the picture on the right side). To obtain a high-quality fluid surface, we implement a surface reconstruction algorithm based on dual contouring. In this project, we also use a CCD (Continuous collision detection) algorithm to tackle the tricky collision problem.
