RESEARCH INTERESTS

 

Generally, I am interested in almost all areas related to Computer Graphics, like Visualization, Animaiton, Geometric Modeling, Physically-based Modeling and Simulation, Human-Computer Interaction, Virtual Reality and Virtual Environments, Surgical Simulation, Medical Image Analysis, Computer Vision, etc.

Specifically, my previous and current researches are mainly focused on the point-based surface modeling, mesh-free surface and volumetric simulation and animation, point-surface parameterization, surface and volumetric mapping, mesh-free surgical simulation, etc.

Spectral Surface Deformation
The geometry and motion of the original irregular meshes can be compactly encoded using the low-frequency spectrum of the manifold surfaces. Using the spectral method, the size of the linear/nonlinear deformation system can be significantly reduced to achieve interactive computational speed for manipulating large triangle meshes...
