I want to create a demo that has something like a cockpit view. I read an ealier topic about adding a background to a scene where you would use an ortho projection for the background and a perspective for everything else.
So the dilemma is, do I use a mask and the stencil buffer for the cockpit, or just draw everything and after that just draw the cockpit over top using an ortho projection?
I have the stencil buffer version working fine but is it worthwhile exploring the other way? I could get rid of the stencil buffer altogether that way, but then why is it common practice to use it in these cases?
