I have a number of (opaque) objects created using the glGenLists() glNewList() utilities. As generated, the Alpha values are all set to 1
Is there a way to make these objects when summoned blend into the scene (sort of as if they were being teleported using the Star Trek transporter). Likewise, I'd also like them to dissolve away when dismissed.
I could of course use time-varying alpha blending in a subroutine if they weren't list objects, but I'm wondering if there's a performance penalty associated with that.
What I'm really trying to do is replace larger coarser ground texture quads with finer smaller quads as I descend in altitude from a satellite while looking down.
