Extended diffuse reflection model for reflectance estimation

We analyse some recent approaches to the global illumination problem by introducing the corresponding reflection operators, and we demonstrate the advantages of a two-pass method. A generalization of the system introduced by Wallace et al. at Siggraph '...

Diffuse objects generally tell us little about the surrounding lighting, since the radiance they reflect blurs together incident lighting from many directions. In this paper we discuss how occlusion geometry can help invert diffuse reflectance to ...

Traditional image texture mapping can increase abundant details for virtual object. As virtual lighting condition varies, textures lack of realistic representation with dynamically varying with lighting, due to pictures are captured in especial lighting ...
