The only problem is, I have the center of my rectangle in coordinates with respect to the center of the sphere, but my other points are relative to that coordinate and lie in the tangent plane at that point on the sphere. I need to figure out how to 'smooth' out that plane onto the surface of the sphere, so I can build a Transform to convert these 'local' coordinates to coordinates with respect to the center of the sphere... I don't understand how I can do this using polar coordinates...
