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?
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?
