Currently, I am a PhD student of the Computer Graphics group in University of Southern California. I received my master degree and bachelor degree from Department of Computer Science and Technology, Tsinghua University, in 2007 and 2005 respectively.

My research interests include computer graphics and solid modeling.
I am particularly interested in feature sensitive mesh processing, OcTree-based visulization and registration.

Editing The Topology of 3D Models by Sketching

We present a method for modifying the topology of a 3D model with user control. The heart of our method is a guided topology editing algorithm. Given a source model and a user-provided target shape, the algorithm modifies the source so that the resulting model is topologically consistent with the target. Our algorithm permits removing or adding various topological features (e.g., handles, cavities and islands) in a common framework and ensures that each topological change is made by minimal modification to the source model. To create the target shape, we have also designed a convenient 2D sketching interface for drawing 3D line skeletons. As demonstrated in a suite of examples, the use of sketching allows more accurate removal of topological artifacts than previous methods, and enables creative designs with specific topological goals.
