Detailed Description

SpherePlaneProjector projects points onto a sphere, failing which it project onto a plane oriented to the viewing direction.

Member Function Documentation

osg::Quat osgManipulator::SpherePlaneProjector::getRotation ( const osg::Vec3d p1,
bool  p1OnSphere,
const osg::Vec3d p2,
bool  p2OnSphere,
float  radialFactor = 0.0f 
) const
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.

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.
