I have asked many times, in this forum, how i can make shadows and multitexturing with my old Viper 330, and i haven’t got a complete answer to my problem.
After months of searching i have found a demo talking about FAKE multitexturing and lightmaps. And voila, my Riva128 can render lighmaps.
Now the problem is somewhere else. Where can i find a tutorial or any kind of DETAILED resource on Projective Texturing using OpenGL??? I have download a demo from somewhere (i don’t remember where) that illustrates exactly this thing. BUT the code was a little comfusing and because i don’t want to use something that i don’t understand, i would like to know if there is anything talking about Projective texturing in detail.
I read from time to time in some “non-OpenGL specific papers” that with projective texturing you can make shadows for static objects in initialization and that you can make real-time lighting effects with lightmaps and projective texturing. That’s why i am asking for a tutorial.
Thanks in advance.
PS.: By the way can anyone suggest a better than Riva 128 card in PCI slot. You see, i have and old machine and i don’t have AGP. Any suggestion accepted.
