Min-Zhi Shao's area of research is realistic image synthesis in computer graphics, particularly the radiosity method. Recently, he has developed a gathering and shooting overrelaxation radiosity method [30]. In his algorithm, the conventional progressive refinement method is modified to make optimal use of the visibility information computed in each iteration: the light energy is first gathered from all visible patches and then immediately reshot to the environment together with the previously accumulated unshot light energy. Based on a concise record of the history of the unshot light energy distribution in the environment, a solid convergence speedup is achieved with little additional computation and memory usage. His future research is to develop and implement more efficient algorithms and techniques for rendering dynamic and complex environments.
