makVrv::DtVertexUpdater Class Reference

Vertex Updater.

The DtVertexUpdater class is the glue between a multi-point object and the vertices that are used for visualizion on that multi-point object. The scene object that is part of this class is not in and of itself updated, however, it is inspected for the points in that scene object, and, using those points, updates a scene object "point" that is used on screen to visualize that vertex. The DtEnvironmentalVertexVisualizer class uses this class to tie the vertices it creates (DtEnvironmentalPointKinStateVisualizers) to the multi-point object that is used to position those vertices. This class is used when a multi-point object is attached to another object. As the multi-point object is updated when the object it is attached to moves, this updater sees those changes and applies them to the scene object points that are associated with this class. There will be one vertex added for each point in the scene object associated with this updater.

Constructor & Destructor Documentation

makVrv::DtVertexUpdater::DtVertexUpdater	(	DtDe &	de,
		DtUniqueID	id
	)

CTOR.

Parameters

[in]	de	is the display engine.
[in]	id	is a unique identifier for this distributed object.

virtual makVrv::DtVertexUpdater::~DtVertexUpdater ( )

virtual

Virtual DTOR.

Member Function Documentation

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

virtual

The update function called by DtTickableManager during update-ticks.

Parameters

[in]

tNow

is the current time-stamp.

Note

All classes deriving from DtMultiPointSceneObjectUpdater must call DtVertexUpdater::update() AFTER their own update completes for chaining (and pass-thru) to work correctly.

Reimplemented from makVrv::DtSceneObjectUpdater.

virtual void makVrv::DtVertexUpdater::addPoint ( int  index, DtSceneObject *    )

virtual

Adds a new point to move at the specified index.

Parameters

[in]	position	index. If -1 adds to the end
[in]	scene	object of the point to position

virtual void makVrv::DtVertexUpdater::removePoint ( int  index )

virtual

Removes a point at the given index.

Parameters

[in]

position

index

virtual void makVrv::DtVertexUpdater::slot_pointObjectToBeDeleted ( const DtUniqueID &  id )

protectedvirtual

Called when point scene object is deleted, see if this object is one that is under this objects point list. If it is, remove.
