Maybe a different subject will inspire some help? basically, I have video that was shot on a mirrored spherical ball.. this gives a circular image inside a rectangular video, I've figured out how to crop it so that I just get the square that surrounds the circle, but I cannot figure out how to correctly map this texture onto a sphere so that it is only on one hemisphere and so that the circle's circumference is on a "great circle" of the sphere? [ie it the circle is warped out so that it becomes a hemisphere].
I figure maybe I have to do some GEMgl stuff for this? if anyone has done this, would you please share? If not, any advice?
