Detailed Description

CylinderPlaneProjector projects a point onto a plane relative to the given cylinder. For most cases, the plane will be parallel to the cylinder axis oriented towards the eyepoint. When the eyepoint and cylinder axis are close to parallel, then it will project onto a plane perpendicular to the cylinder.

Member Function Documentation

getRotation()

osg::Quat osgManipulator::CylinderPlaneProjector::getRotation	(	const osg::Vec3d &	p1,
		const osg::Vec3d &	p2 ) const

Generates a rotation about the cylinder axis based upon the incoming projected points on the plane computed from project().

Parameters

[in]	p1	Initial projection point
[in]	p2	Second projection point

Returns

osg::Quat Rotation about cylinder axis

project()

virtual bool osgManipulator::CylinderPlaneProjector::project ( const PointerInfo & pi, osg::Vec3d & projectedPoint ) const

virtual

Calculates the object coordinates (projectedPoint) of a window coordinate (pointToProject) when projected onto the given plane. Returns true on successful projection.

Parameters

[in]	pi	Incoming intersection information
[out]	projectedPoint	Point located on the given plane

Returns

bool Whether the projection onto the plane was successful.

Reimplemented from osgManipulator::CylinderProjector.
