Chuang's primary research interests are in the areas of 3D graphics, virtual reality, and geometric modeling. In 3D graphics, he works on the modeling and the real-time rendering techniques for 3D game design, virtual reality and visual simulation. Current research topics include global illumination, hybrid rendering, mesh processing techniques (including level-of-detail modeling, mesh parameterization, deformation, and editing), and collision detection. His work on geometric modeling focuses on how to effectively represent, manipulate, and render complex surfaces and solids.
