I have some panoramic video that I want to use to texture a hemisphere [or rather, the bottom half of a sphere].

I cannot simply texture the sphere with the video because the warping is not correct.. it seems that I need some sort of non-rectangular warping of the image before I texture the object, or a non-rectangular mapping of the texture onto the sphere.

Any ideas or advice? Does anyone else have experience working with panoramic video in Gem?
