PENTA: the whole file is freakin penta...
|
|
|
|
Same as gl_bumpmap.c but geforce3&4 optimized
|
|
These routines require 4 texture units an some need nvidia shaders
|
|
|
|
Most lights reqire 2 passes this way
|
|
1 diffuse
|
|
2 specular
|
|
|
|
If a light has a cubemap filter it requires 3 passes
|
|
1 attenuation
|
|
2 diffuse
|
|
3 specular
