Member Function Documentation

virtual void makVrv::DtEllipseUpdater::update ( double simTime )

virtual

If origin or to point have changed, recalc orientation.

virtual void makVrv::DtEllipseUpdater::setOrientationDelta ( double )

virtual

virtual void makVrv::DtEllipseUpdater::setClamped ( bool )

virtual

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

virtual void makVrv::DtEllipseUpdater::setPosition	(	int	,
		const DtVector &
	)

virtual

Sets positions of ellipse.

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

virtual void makVrv::DtEllipseUpdater::setSceneObject ( DtSceneObject * sceneObject )

virtual

Set the scene object to be updated.

Parameters

[in] sceneObject is the scene object to receive updates.

virtual bool makVrv::DtEllipseUpdater::needsUpdate ( DtTime tNow )

virtual

The check function called by DtTickableManager to verify if an update is required.

If this function returns true, the DtTickableManager will then call update().

Parameters

[in] tNow is the current time-stamp.

Return values

true	if this object needs to be ticked.
false	otherwise.

Reimplemented from makVrv::DtTickable.

Reimplemented in makVrf::DtVrfRangeEllipseUpdater.

virtual void makVrv::DtEllipseUpdater::setUpdaterPosition	(	int	vtx,
		const DtVector &	pos
	)

virtual

Set the position of a vertex.

Parameters

[in]	vtx	is the vertex.
[in]	pos	is the position to set.

virtual void makVrv::DtEllipseUpdater::setUpdaterOrientation	(	int	vtx,
		const DtTaitBryan &	ori
	)

virtual

Set the orientation of a vertex.

Parameters

[in]	vtx	is the vertex.
[in]	ori	is the orientation to set.

virtual void makVrv::DtEllipseUpdater::setDynamicOrigin ( bool )

virtual

Sets whether or origin is set in the updater or retrieved from the scene object.

Default is false (retrieved from origin)

virtual bool makVrv::DtEllipseUpdater::computeGroundClampingHit	(	const DtVector &	up,
		const DtVector &	unclampedPosition,
		DtVector &	hitLocation,
		DtVector &	hitNormal
	)

protectedvirtual

virtual DtTaitBryan makVrv::DtEllipseUpdater::computeOrientation	(	const DtVector &	pos,
		double	topoHeading
	)		const

protectedvirtual

Computes orientation of the ellipse as level to terrain.

virtual void makVrv::DtEllipseUpdater::slot_sceneObjectToBeDeleted ( const DtUniqueID & id )

protectedvirtual

DtSceneObject::ObjectTransform& makVrv::DtEllipseUpdater::getOrCreateTransform ( int vtx )

private

Helper function to get the transform at a given vertex.

If the vertex is above range, new transforms are created.

Parameters

[in] vtx is the vertex of the transform to get.

Returns: The transform at the given vertex.

Exceptions

DtCorruptedState if vtx is less than zero.
