		makVrv::DtUniqueID	id,
		bool	doNotAddToMgr = `false`
	)

CTOR.

virtual makVrf::DtCircleUpdater::~DtCircleUpdater ( ) [virtual]

DTOR.

virtual void makVrf::DtCircleUpdater::update ( double simTime ) [virtual]

If origin or to point have changed, recalc orientation followed by updateSceneObject()

virtual void makVrf::DtCircleUpdater::setOrientationDelta ( double ) [virtual]

virtual void makVrf::DtCircleUpdater::setPosition	(	int	,
		const DtVector &
	)		`[virtual]`

Sets positions of circle.

Will update orientation and radii appropriately. Vector is considered in local coordinates

virtual void makVrf::DtCircleUpdater::setClamped ( bool ) [virtual]

Sets to clamp. Will recalculate orientations and clamp position on next update.
