It's the same problem : points behind the camera cannot be positionned correctly, thus the polygon is deformed.

A solution I came to is to compute the intersections of the polygon and the camera render limit to create new points that are not behind the camera.

Simplified math problem asked here http://math.stackexchange.com/questions/1720450/arc-intersection-on-a-sphere

mistic100 modified the milestones: 3.2.1, 3.2.0
