报告题目：Interactive Fur Shaping & Rendering 报告人：Prof. Hanqiu Sun 时间：10月27日上午10：00-11：00 报告内容摘要：Furry surfaces are crucial in representing the realistic appearance of virtual creatures and cartoon-style objects/bodies. It is highly demanding to model and render the realistic furry effects in interactive gaming and virtual environments. Most of the hair/fur modeling systems proposed geometry-based representations so the systems don’t directly support interactive modeling and rendering of virtual furry creatures. Our work is motivated for representing the realistic furry surfaces based on the non-uniform layered approach, and supporting users the interactive tools to intuitively shape dense, messy fur over the bodies with the realistic rendering effects. These include fur combing, wind blowing, pulling, interpolating, smoothing and disturbing, thus users can intuitively design and manipulate the furry surfaces over the bodies with simple user input. Further, we developed layered shadow maps for the realistic self-shadowing effects of fur, which can significantly enhance the realistic appearance of furry creatures. Using the interactive tools, users can intuitively create the furry shapes of virtual creatures, and visualize the realistic rendering of edited fur instantly. Our interactive fur system utilizes GPU-accelerated processing, and supports the intuitive user input for shaping the furry surfaces of virtual creatures. Also, other current research projects we have worked on will be briefly introduced at the end. 孙汉秋教授简历：Prof. Sun received her M.S. in electrical engineering from University of British Columbia, and Ph.D. in computer science from University of Alberta, Canada.
