User-Defined Shading Models for VR Applications

Quite a few techniques have been proposed on how to implement more complex and realistic shading models with graphics hardware [5, 7], making them useful for VR applications. Still, these techniques are rarely used, probably due to two reasons: complex implementation issues, and unintuitive parameters for the used shading models. We propose to use a simple technique called "NDF shading". It allows an artist to handcraft shading models; shape and color of highlights are simply stored in a bitmap. Anisotropic shading models can also be created.
