POWERVR Insider SGX Bump Mapping Demo

This demo illustrates the massive increase in visual quality offered by POWERVR SGX advanced shader technology. The stack of three blocks on the left illustrates basic texture mapping as is offered by competing products. The blocks in the centre illustrate DOT3 per-pixel lighting where the diffuse lighting calculations are done at the per-pixel level rather than the per-vertex level; the POWERVR MBX technology offers this level of quality.

Finally the blocks on the right side show parallax bump-mapping with per-pixel diffuse and specular lighting. Parallax bump-mapping is an advanced technique that produces a proper parallax effect when the camera pans across a surface. This approximates the visual quality of displacement mapping, but with no increase in polygon count; for this reason this technique is sometimes referred to as virtual displacement mapping.
