PENTA: the whole file is freakin penta... Same as gl_bumpmap.c but Radeon 8500+ optimized These routines require 6 texture units, vertex shader and pixel shader This could be further optimized for Radeon 9700 (specular exponent for example), but would need better documentation and extension. All lights not require only 1 pass: 1 diffuse + specular with optional light filter */ #include "quakedef.h" #include "glATI.h" PFNGLGENFRAGMENTSHADERSATIPROC qglGenFragmentShadersATI = NULL; PFNGLBINDFRAGMENTSHADERATIPROC qglBindFragmentShaderATI = NULL;
