Hy. Can you advice me a tutorial ,a link or a book that explain the teory of the parallax mapping? In particular the behind mathematics. I dont understand all the tangent coordinate space. In particular: The x and the y are the u and v in tangent space , but the third coord is the z? and is along the normal? But why be do this coord transform(from the word to the tangent space)? what help do? What do the parallax mapping? in particular what are the offsets and why i must offset? they are relative to the U and the V? thanks. [Edited by - giugio on April 15, 2009 2:36:35 AM]
