Hi,
here is a patch for a first try to implement ComputeSphereVisibility. Any feedback is welcome.
I think you can simplify the sphere-plane intersection. Just compute the signed distance D of the sphere center from the plane. If D > r, the sphere is visible. If -r <= D <= r, the sphere is partially visible. if D < -r, it's invisible.
Also, wine people like tests. You should probably add some.
