Verification of rendering quality from measured BTFs
One of the most important, still unsolved problems in computer graphics is the generation of predictive imagery, i.e., images that represent perfect renditions of reality. Such pe...

Minification influences spatial judgments in virtual environments
Distances in immersive virtual environments (VEs) have been commonly reported as being spatially compressed while the same judgments are performed accurately in real space. Previo...
