can OpenGL do sphere transforms mapped onto flat?

I made this with blitzplus a few years ago.


of course I had to hard code the transforms to run on the cpu. Wondered if there's openGL commands that could do them on the gpu? If so I could rewrite this for blitzmax, and it would run much faster, right?
It didn't run in real time in blitzplus. The animation is a compilation of bmps that the code slowly generated, like one every 500ms.
