I need to talk to someone that read NeHe's tutorial on BumpMapping... Was MAXEMBOSS the frequency with which the underneath(second pass,inverted bump)repeats?? Is there any game that uses EMBOSS cause to me its a little slow.Do you know other algorithms to do that? [Edited by - Daos on August 31, 2004 2:14:12 PM]

Funny thing, there's an NEHE forum!

Emboss Bump Mapping is an obsolete technique right now and its difficult to code, so i suggest to learn DOT3 Bump Mapping (called Normal Mapping) which is widly used and easier to code and gives much better results
for resources on DOT3 Bump Mapping refer to those links:

for more help you can search the forums here and in Gamedev's OpenGL and in OpenGL.org forums

Agreed dot3 looks much better.
