Damn, my previous post wasn’t posted, dunno why.
Anyway, here it goes:
Vertex programs are becoming pretty popular recently. I was wondering if it is still possible to transform the vertices once in a multi-pass environment ( like with CVAs ). If yes, how ? Are there new extensions for that or what ?
I am also wondering what is the speed hit when using a standard vertex program ( to do transform & lighting without any special effect ) ? Ie, is it as fast as the T&L we all know, or slower ? And finally, if i have 8 lights in my scene, will i have to make the 8 lighting calculations in the vertex shader myself ? Is there a speed hit too, compared to standard opengl lighting ?
I’m so curious
