Detailed Description

A DtAttachableUpdater updates a scene an object that can be positioned in the scene by (possibly) attaching it to one or more other scene objects.

Note that this is not a DtSceneObjectUpdater; It can't be linked to other DtSceneObjectUpdaters.

Member Function Documentation

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

virtual

Does this updater need to update?

Reimplemented from makVrv::DtTickable.

virtual void makVrv::DtAttachableUpdater::addAttachedPoint	(	const DtVector &	position,
		int	targetVertexIndex
	)

virtual

Add a (vertex) attach point.

If multiple attach points are specified each will update its corresponding vertex in the scene object being updated

virtual void makVrv::DtAttachableUpdater::addAttachedPoint	(	DtUniqueID	uniqueID,
		int	targetVertexIndex
	)

virtual

Add a (object) attach point.

If multiple attach points are specified each will update its corresponding vertex in the scene object being updated

virtual void makVrv::DtAttachableUpdater::addAttachedPoint	(	DtUniqueID	uniqueID,
		int	vtx1,
		int	vtx2,
		double	proportion,
		int	targetVertexIndex
	)

virtual

Add a (linear) attach point.

If multiple attach points are specified each will update its corresponding vertex in the scene object being updated

virtual const AttachedPoint& makVrv::DtAttachableUpdater::attachedPoint ( int targetVertexIndex ) const

virtual

Returns the attached point at the given vertex.

This method returns a copy of the current state of the attached point. If an attached point with the given index could not be found, this method returns an AttachedPoint with type AttachedPointTypeInvalidObject.

virtual void makVrv::DtAttachableUpdater::setPositionOffset ( const DtVector & offset )

virtual

positionally offset the attach points by this amount.

This is in the coordinate system of the object attached to

virtual void makVrv::DtAttachableUpdater::setWorldPositionOffset ( const DtVector & offset )

virtual

positionally offset the specific attach point by this amount in world (database) coordinates.

Will be used in conjunction with the overall position offset

virtual void makVrv::DtAttachableUpdater::setPositionOffset	(	const DtVector &	offset,
		int	vtx
	)

virtual

positionally offset the specific attach point by this amount.

This is in the coordinate system of the object attached to. Will be used in conjunction with the overall position offset

virtual void makVrv::DtAttachableUpdater::setOrientationOffset ( const DtTaitBryan & offset )

virtual

rotationally offset the attach points by this amount.

This is in the coordinate system of the object attached to

virtual void makVrv::DtAttachableUpdater::setWorldOrientationOffset ( const DtTaitBryan & offset )

virtual

rotationally offset the attach points by this amount in world (database) coordinates

virtual void makVrv::DtAttachableUpdater::setAttachedPointMode	(	unsigned int	mode,
		int	vtx
	)

virtual

Set whether an attached point updates position, orientation, or both.

virtual void makVrv::DtAttachableUpdater::update ( DtTime tNow )

virtual

Calls doAttachment()

Implements makVrv::DtTickable.

Reimplemented in makVrv::DtAttachableEntityFanUpdater, makVrv::DtLineModelUpdater, and makVrv::DtAttachableIntervisibilityUpdater.

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

virtual

Set the scene object to be updated.

Parameters

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

Reimplemented in makVrv::DtLineModelUpdater, and makVrf::DtRangeRingUpdater.

virtual void makVrv::DtAttachableUpdater::doAttachment ( DtTime tNow )

virtual

Find the actual position and orientation based on the attach points and offsets.

DtTime makVrv::DtAttachableUpdater::lastUpdateTime ( ) const

inline

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

protectedvirtual

Reimplemented in makVrf::DtAttackLineAttachableUpdater.

protectedvirtual

virtual void makVrv::DtAttachableUpdater::slot_attachedUpdaterToBeDeleted ( const DtUniqueID & id )

protectedvirtual

virtual bool makVrv::DtAttachableUpdater::pointLocationAndOrientation	(	AttachedPoint *	point,

	)

protectedvirtual

virtual void makVrv::DtAttachableUpdater::removeAttachedPoint	(	int	vtx,
