Detailed Description

Multi Point Scene Object Updater.

DtMultiPointSceneObjectUpdater is a distributed object managed by DtTickableManager. It provides an API and infrastructure used by deriving objects to update the positions of multi point scene objects in render space. DtMultiPointSceneObjectUpdaters may be chained together in a list to perform multiple position and/or orientation transformations. For example, one updater might dead reckon position and orientation based on kinematic info, the next in the chain could ground clamp the object. A third might adjust the ground clamped position to support terrain scaling.

Constructor & Destructor Documentation

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

CTOR.

Parameters

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

virtual makVrv::DtMultiPointSceneObjectUpdater::~DtMultiPointSceneObjectUpdater ( )

virtual

Virtual DTOR.

Member Function Documentation

virtual void makVrv::DtMultiPointSceneObjectUpdater::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 DtMultiPointSceneObjectUpdater::update() AFTER their own update completes for chaining (and pass-thru) to work correctly.

Reimplemented from makVrv::DtSceneObjectUpdater.

Reimplemented in makVrv::DtMultiPointEmbarkationUpdater.

virtual void makVrv::DtMultiPointSceneObjectUpdater::setInputPositions ( const std::vector< DtVector > & positions )

virtual

Set the positions input to this updater.

Parameters

[in] positions is the position to use.

Reimplemented in makVrv::DtMultiPointEmbarkationUpdater.

virtual void makVrv::DtMultiPointSceneObjectUpdater::setOutputPositions ( const std::vector< DtVector > & positions )

virtual

Output the resultant positions.

If there is a next updater, this will call that updater's setInputPositions with the result. Otherwise the result will be provided to the specified scene object

Parameters

[in] position is the position to set.

Reimplemented in makVrf::DtVrfMultiPointEmbarkationUpdater, and makVrv::DtOverlayPolygonEmbarkationUpdater.
