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

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]p1Initial projection point
[in]p2Second projection point
Returns
osg::Quat Rotation about cylinder axis
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]piIncoming intersection information
[out]projectedPointPoint located on the given plane
Returns
bool Whether the projection onto the plane was successful.

Reimplemented from osgManipulator::CylinderProjector.
