Detailed Description

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

Member Function Documentation

◆ getRotation()

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

◆ isProjectionOnSphere()

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.

References _onSphere.

◆ project()

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.
