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.

Definition at line 207 of file Projector.h.

virtual bool osgManipulator::SpherePlaneProjector::project ( const PointerInfo &  pi, osg::Vec3d &  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.
