Xavier Granier - Computer Graphics & Optics


My main research background is realistic rendering and global illumination. I have extended his interest to acquisition and modeling of material properties and light sources (at University of British Columbia - Vancouver - Canada), sketching interactions (with Zheijiang University - Hangzhou - China) and expressive rendering (previously called non-photorealistic rendering). Currently, the main focus of my research is the accurate simulation of optical phenomena and the creation of new technologies that combine the strengths of optics and computer graphics. I mainly consider impacts of 3D technologies as tools for studies, preservation and diffusion of Cultural Heritage.
