virtual bool osgManipulator::SpherePlaneProjector::project	(	const PointerInfo &	pi,
		osg::Vec3 &	projectedPoint
	)			const [virtual]

Calculates the object coordinates (projectedPoint) of a window coordinate (pointToProject) when projected onto the given sphere.

Returns true on successful projection.

Reimplemented from osgManipulator::SphereProjector.

bool osgManipulator::SpherePlaneProjector::isProjectionOnSphere

(

)

const [inline]

Returns true if the previous projection was on the sphere and false if the projection was on the plane.
