Talk:Normal mapping
From Wikipedia, the free encyclopedia
Does Doom 3 use normal mapping or bump mapping? Both articles claim it for themselves... 202.150.96.34 07:30, 10 Feb 2005 (UTC)
- Normal mapping is a subset of bump mapping. Bump mapping covers all techniques, normal mapping is simply one technique of bump mapping. Goosey

[edit] Halo 2
I would have thought that Halo 2 was just as famed for its use of normal mapping as Doom 3 [assuming that as mentioned above, it actually uses normal rather than bump mapping] and Half Life 2. But maybe that's just me...
Does Half-Life 2 use normal mapping? I don't remember that but then again I never played through the game.
Also, which ps2 and gc games have used normal mapping? What are the conditions in which it was used? I know that Super Smash Bros. Melee used it on at least two trophies (dk and bowser) but not during actual gameplay.
[edit] Code For Normal Mapping
For the above, uh, yes Half-Life 2 uses normal mapping. Ok. I was wondering if anyone has some Cg or HLSL shader code for normal mapping that they could place on this wiki.
- GLSL for bump mapping is the closest I have. Although the only difference is that bump mapping computes the normal, while normal mapping just looks it up in a table. Of course, my code would have to be checked first to make sure it actually works the way it's supposed to anyway.Tommstein 18:55, 4 December 2005 (UTC)
[edit] Is Normal mapping 3D?
Maybe this is a dumb question but I don't understand the difference between bump mapping (which is not 3D as I understand it but gives the illusion of displacement) and normal mapping.
In other words, if you apply a bump map of a deep gash onto a sphere, and then rotate the sphere in 3D to see the gash from the "side", you cannot see into the gash because there is only an illusion of a gash painted onto the sphere geometry. Is this true for normal mapping as well?
- Normal mapping has the same limitations as bump mapping. The difference is an implementation detail. -Ahruman 23:41, 6 April 2006 (UTC)
[edit] Article is too difficult to understand
I think this article uses the language of a professional 3d designer. I know it's difficult to explain things about mapping and design without using such complicated terms, but maybe this could be simplified a little for all of us simple mortals out there.

[edit] How do I create a normal map of a texture on a 3d model?
I can create a low resolution 3d model with a texture wrapped onto the model. I have a scanner that scans a face and wraps the face photograph onto the 3d geometry. What is the best way, or best software, to create the normal map so that the low resulution geometry displays as if it were high resolution using the normal map? I'm sure lots of people want to know this. —The preceding unsigned comment was added by 24.64.227.161 (talk) 00:49, 11 December 2006 (UTC).
