Hi,
My Engine supports only Per Pixel Lightning for NIVIDIA Cards. I’d like to use PPL for ATI Radeon series too. But I don’t have a ATI card so I need some help for converting my code for ATI users.
Here’s the first function for the NVIDIA Register Combiners.
// **********************************************
bool Init_Register_Combiners() // Register Combiners Initialisation
{
// The name of the extension
char *Extension;Extension = (char *) glGetString(GL_EXTENSIONS); if (!(strstr(Extension, "GL_NV_register_combiners")) == 1) { // The "GL_NV_register_combiners" extension is not supported MessageBox(NULL,"GL_NV_register_combiners","Extension not supported :",MB_ICONERROR); return false; }glCombinerParameterfvNV = (PFNGLCOMBINERPARAMETERFVNV) wglGetProcAddress(“glCombinerParameterfvNV”);
glCombinerParameterivNV = (PFNGLCOMBINERPARAMETERIVNV) wglGetProcAddress(“glCombinerParameterivNV”);
glCombinerParameterfNV = (PFNGLCOMBINERPARAMETERFNV) wglGetProcAddress(“glCombinerParameterfNV”);
glCombinerParameteriNV = (PFNGLCOMBINERPARAMETERINV) wglGetProcAddress(“glCombinerParameteriNV”);
glCombinerInputNV = (PFNGLCOMBINERINPUTNV) wglGetProcAddress(“glCombinerInputNV”);
glCombinerOutputNV = (PFNGLCOMBINEROUTPUTNV) wglGetProcAddress(“glCombinerOutputNV”);
glFinalCombinerInputNV = (PFNGLFINALCOMBINERINPUTNV) wglGetProcAddress(“glFinalCombinerInputNV”);glGetCombinerInputParameterfvNV = (PFNGLGETCOMBINERINPUTPARAMETERFVNV) wglGetProcAddress(“glGetCombinerInputParameterfvNV”);
glGetCombinerInputParameterivNV = (PFNGLGETCOMBINERINPUTPARAMETERIVNV) wglGetProcAddress(“glGetCombinerInputParameterivNV”);
glGetCombinerOutputParameterfvNV = (PFNGLGETCOMBINEROUTPUTPARAMETERFVNV) wglGetProcAddress(“glGetCombinerOutputParameterfvNV”);
glGetCombinerOutputParameterivNV = (PFNGLGETCOMBINEROUTPUTPARAMETERIVNV) wglGetProcAddress(“glGetCombinerOutputParameterivNV”);
glGetFinalCombinerInputParameterfvNV = (PFNGLGETFINALCOMBINERINPUTPARAMETERFVNV) wglGetProcAddress(“glGetFinalCombinerInputParameterfvNV”);
glGetFinalCombinerInputParameterivNV = (PFNGLGETFINALCOMBINERINPUTPARAMETERIVNV) wglGetProcAddress(“glGetFinalCombinerInputParameterivNV”);return true;
}
// **********************************************
void Setup_Register_Combiners() // Setup the Register Combiners
{
// Register Combiners Initialisation. We use 1 Register
glCombinerParameteriNV(GL_NUM_GENERAL_COMBINERS_NV, 1);// Light Color
float Light_Color = { 1.0f, 1.0f, 1.0f, 1.0f };// We give the Light Color params to the Register Combiners
glCombinerParameterfvNV(GL_CONSTANT_COLOR0_NV, (float *) &Light_Color);// Register Combiners Calcul for the Light Attenuation
// ( 1 * Texture0 + 1 * Texture1)
glCombinerInputNV(GL_COMBINER0_NV, GL_RGB, GL_VARIABLE_A_NV, GL_TEXTURE0_ARB, GL_UNSIGNED_IDENTITY_NV, GL_RGB);
glCombinerInputNV(GL_COMBINER0_NV, GL_RGB, GL_VARIABLE_B_NV, GL_ZERO, GL_UNSIGNED_INVERT_NV, GL_RGB);

glFinalCombinerInputNV(GL_VARIABLE_A_NV, GL_SPARE0_NV, GL_UNSIGNED_IDENTITY_NV, GL_RGB);
glFinalCombinerInputNV(GL_VARIABLE_B_NV, GL_ZERO, GL_UNSIGNED_IDENTITY_NV, GL_RGB);

glFinalCombinerInputNV(GL_VARIABLE_G_NV, GL_ZERO, GL_UNSIGNED_INVERT_NV, GL_ALPHA);// We enable the Register Combiners
glEnable(GL_REGISTER_COMBINERS_NV);}
