View Full Version : Relief mapping and Parallax mapping

I have question on RM. I have looked at it a bit, and not 100% sure, but does RM modify the texture coords that you use to access your textures like parallax mapping does? Thanks

Yes, but it calculates the right coordinate by doing intersections with depth map.

It does this by doing a search, meaning it accesses the depth-map multiple times to narrow down to the correct texture-coordinate. Depending on how many steps are used for the search, the result is more or less precise (and more or less slow to compute).
