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. -f.r.
