Hi,
Is there any way to use Secondary color Alpha in Geforce/Geforce2?
I see that there is an Extension for this but My driver is not exposing this extension. I am using the register combiners and I badly want support for secondary color alpha through vertex arrays, Can someone tell me if this is possible?
glSecondaryColorPointerEXT(4,GL_FLOAT,0,ptr);
This would help me render upto two lights in one pass using just a Geforce256/Geforce2, I saw the extension specifications in the NVIDIA page but it doesnt look complete. Could anybody let me know if I can use this in arrays without any extension being enabled?
Why have a secondary color Alpha in register combiners if you cant use it anywhere? Doesnt really make sense to me. Somebody from NVIDIA please reply!. I guess the developers in NVIDIA simply assume that the whole world has Geforce3+ Hardware and only work on that when a lot of their extensions can also work on Geforce range of cards.
And… why is the Geforce256/Geforce2 completely forgotten by guys at NVIDIA? Simple extensions like the GL_NV_secondary_color_alpha would be beneficial even on a Geforce256!! What about all those guys who spend 250-300$ on their GeForce256/2 etc?
Thanks,
Sundar
