Normal vs Displacement maps
polycounter lvl 17
Hi all. Quick question, looking at artistic, not technical answers:
Normal maps and displacement maps would seem to affect a lot of the same spots on a texture - would I be correct in understanding that while a displacement map is used to alter the height of the poly or micropoly, the normal map then provides the lighting information?
In other words, I should make sure my normal maps pay attention to the edges of a surface, while the displacement map does the work of raising or lowering the actual surface?

Displacement maps offset the rendering of geometry so the resulting render is raised just as it would have been if you had modeled in that detail with polygons.
Parallax also uses height/displacement maps, and is a more common realtime effect.
