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 to Zhejiang University. With my move to Zhejiang University, I am actively looking for self-motivated graduate students to start a research group in computer graphics and parallel computing.

Research

My research concentrates on geometry, texture and real-time computer graphics. These lines of research have led to a number of publications over the past few years, including 17 SIGGRAPH papers. Some of the 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).

Geometry & Texture:
- Shape deformation: Poisson mesh editing, volumetric graph Laplacian, subspace mesh deformation, 2D shape deformation, subdivision surface deformation, mesh puppetry, mesh animation editing, dynamic skinning
- Mesh parameterization and texture mapping: iso-charts (UVAtlas), texture montage, spherical parameterization (surface filtering)
- Surface texture synthesis: progressively-variant texture, BTF painting, mesh quilting (geometric texture)
Real-Time Computer Graphics: We are developing data structures, algorithms and programming tools to harness the formidable raw processing power of modern graphics hardware, and to accelerate the computations in major areas of computer graphics (see my recent overview talk).
- Geometry: subdivision surface deformation, parallel surface reconstruction (octree), point cloud modeling (kd-tree)
- Animation: mocap-driven deformation, deformable objects, dynamic skinning
- Rendering: soft shadows (shadow fields, SH exponentiation, SH scaling), dynamic BRDF, dynamic refraction, scattering media (smoke, fogshop, light shafts), ray tracing & photon mapping
- Texturing: fast surface texture synthesis, inverse texture synthesis
- Programming tools: 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. We have demonstrated the potential of BSGP through a variety of GPU applications, including a GPU ray tracer, a particle-based fluid simulator, an X3D parser and an adaptive mesh tessellator (download the BSGP compiler and sample code).
