Detailed Description

Provides an algorithm for scaling objects in the scene.

Constructor & Destructor Documentation

virtual makVrv::DtScalingAlgorithm::~DtScalingAlgorithm ( )

virtual

DTOR.

virtual double makVrv::DtScalingAlgorithm::calculateScale	(	const DtOsgCullVisitorParameters &	info,
		const osg::Camera &	camera,
		const osg::Vec3d &	position,
		double	modelRadius,
		DtUniqueID	objectElementId
	)

pure virtual

Calculate the scale factor for an object in the scene.

Parameters

[in]	info	is the cull visitor parameters object, which contains the current XR scale factor setting, as well as other potentially useful information for a scaling algorithm.
[in]	camera	is the current cull or intersector camera, from which the eyepoint can be found, as well as the viewport, model view and projection matrices, if desired.
[in]	position	is the position of the object to be scaled
[in]	modelRadius	is the bounding radius of the object to be scaled
[in]	objectElementId	is the element ID of the object being scaled, if it exists - check first for (DtUniqueID)0.
