Bio: Yu Sheng is a Ph.D. student in the Department of Computer Science, Rensselaer Polytechnic Institute. He holds a B.S. degree from Xi’an Jiaotong University and a M.S. degree from Zhejiang University. His research focuses on global illumination, interactive rendering, spatially augmented reality, and daylighting simulation.

Abstract: Spatial augmented reality (SAR) detaches the displays from users and integrates them into the physical world to create 3D visualization environments. Faithful visualization of computer generated images in SAR environments is still a challenging problem due to many issues, such as non-uniformity in projection devices, and unintentional light scattering. In this talk, I will discuss an interactive daylighting simulation system that allows users to sketch designs with physical walls and explore the lighting simulation. I will also talk about a inverse global illumination to cancel the unintentional light scattering in non-planar display environments using bound constrained optimization.
