A list of ideas for anim8or

Well Steve, the problem is that you're asking me to explain something that I think is beyond my level of...technical prowess :P I'm certain there are hundreds of normal map shaders and articles about utilizing normal maps on the web right now.

Some quick links I pulled off of google:
http://en.wikipedia.org/wiki/Normal_mapping
http://www.3dkingdoms.com/tutorial.htm

http://gamedev.net might be able to shed some light on the subject

Steve:
Raxx, if you could point me to where you got that image of the 3 different kinds of bumpmapping perhaps I could figure out how they made (b).

Raxx:
Well, I got it from this forum article: http://www.game-artist.net/forums/support/7756-bump-maps-vs-normal-maps.html but aside from the first two posts and the last one, there's not a whole lot of "how" that other articles didn't cover, but it might help.

The blender manual also compares between normal maps and bump maps: http://wiki.blender.org/index.php/Manual/Bump_and_Normal_Maps

Really all I do is google "bump vs normal map". Like I mentioned though you'd probably get a better idea if you check out normal map cg/hlsl/glsl shader files...

Steve,
Maybe peoples want to be able to directly  load Normal Maps textures instead of greyscale texture to use their own normal maps (computed from Nvidia Melody or something else, and not from Anim8or) and not just the ones computed by Anim8or. Maybe Anim8or can already do that (i have not tested)
Example:

Maybe peoples also want more depth in the bump map relief. This can be done by more advanced (and slower) technics than simple dot3 Bump Mapping such as paralax Bump Mapping or Relief Mapping (maybe you already use it).
