I am currently a professor in the Computer Science Department of Zhejiang University, and a member of the State Key Laboratory of CAD&CG. I received my BS degree and PhD degree in computer science, both from Zhejiang University. After graduation I spent six years with Microsoft Research Asia, and was a lead researcher of the graphics group before moving back to Zhejiang University. I am actively looking for self-motivated graduate students to start a research group in computer graphics and GPU parallel computing.

Research

My research concentrates on shape modeling/editing, texture mapping/synthesis, real-time rendering, and more recently GPU parallel computing. These lines of research have led to a number of publications over the past few years, including 20 SIGGRAPH papers. Some of these techniques have been integrated into the D3DX library of Microsoft DirectX, licensed to Weta Digital, and adopted by Bungie Studio (I received credit for my light map generation and compression work on Halo 3).

GPU Parallel Computing
- RenderAnts: a Reyes rendering system that runs entirely on GPUs. The system takes RenderMan scenes and shaders as input, generates photorealistic images, and is over one order of magnitude faster than existing CPU-based renderers.
- GPGPU debugger: a new framework for debugging GPU stream programs, which is based on GPU Interrupt, a new mechanism that allows calling CPU functions from GPU code.
- BSGP (bulk-synchronous GPU programming): a new programming language for general purpose computation on GPUs, which makes GPU programs easier to read, write and maintain while preserving high efficiency (download the BSGP compiler).
- GPU data structures: KD-Trees, Octrees (sparse), Octrees (linear), memory-scalable spatial hierarchies
Real-Time Rendering
- Soft shadows: shadow fields, spherical harmonic exponentiation, spherical harmonic scaling
- Dynamic materials: dynamic BRDF, dynamic refraction
- Scattering media: smoke, fog, gradient-based interpolation & sampling
- Global illumination: GPU-based ray-tracing & photon mapping, GPU-based irradiance caching
Texture Mapping/Synthesis
- Texture mapping: iso-charts (DirectX's UVAtlas), texture montage, spherical parameterization
- Texture synthesis: progressively-variant texture, BTF painting, mesh quilting, HDR hallucination, inverse texture synthesis, hair geometry synthesis, motion field synthesis
Shape Modeling/Editing
- Poisson mesh editing, volumetric graph Laplacian, subspace mesh deformation, 2D shape deformation, subdivision surface deformation, mesh puppetry, mesh animation editing, dynamic skinning, joint-aware deformation, out-of-core mesh processing, shape interpolation with dynamics
