Fig.25 on that page.
Is something like this possible for Blender 2.5 (and/or GE)
"Firstly, there’s parallax bump mapping (or virtual displacement mapping). Parallax mapping creates additional apparent depth by displacing the texture coordinates as a function of the viewing angle (Parallax Mapping).
Normal mapping has progressed to a point where, with parallax occlusion mapping, not only do we have a perturbed and parallax surface, but that surface is also self-occluding so that the texture casts shadows across it’s own surface"
It’s just Phenomenal, anyone know if this maybe coming to blender?
here is image of what I’m talking about.
