After you asked me that, I went back to try to figure out what didn't work. It turns out that I was able to get it working with a few small changes. I don't know what the correct parametric equation for moving a camera between two points on the surface of a sphere is. I changed my code to move the camera along a chord from point A to point B and that seems to work just fine. Any idea what the parametric equation for the arc connecting to points on a sphere is?
