Remarks

OIV.Inventor.Projectors.SbSpherePlaneProjector projects a window space point (usually based on the mouse location) onto a surface defined by a sphere and plane cutting through the sphere. Two projected points can produce a rotation about the sphere's center. When the mouse position projects onto the plane, the rotations will be as if the plane is being dragged, causing the sphere to roll beneath it.

Incremental changes (delta rotation) can be computed during interactive sessions. Sphere projectors are typically used to write interactive 3D manipulators and viewers.
