Member Function Documentation

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

virtual

Update the wind direction.

Implements makVrv::DtTickable.

float makVrv::DtShipFlagDirTickable::calcRotAngleForShipFlag	(	DtSceneObject *	sceneObj,
		DtDeadReckonUpdater *	updater,
		DtTime	tNow,
		const DtVector &	windDirVec,
		float	windSpeedMperS
	)

Calculate the rotation about Z for the flag given the ship velocity and wind velocity.

DtVector makVrv::DtShipFlagDirTickable::computeWindVec	(	DtSceneObject *	sceneObj,
		float	windDirRad
	)

Convert the wind angle to a directional vector.

virtual bool makVrv::DtShipFlagDirTickable::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.

virtual void makVrv::DtShipFlagDirTickable::configure	(	osg::Node *	n,
		const rapidjson::Value &	windJsonData
	)

virtual

Configure node based on json data.

virtual void makVrv::DtShipFlagDirTickable::modelToBeDestroyed ( DtModel * model )

virtual

listen to the model to be destroyed signal

virtual void makVrv::DtShipFlagDirTickable::disconnectFromModel ( )

protectedvirtual

internal function to disconnect from the model

virtual void makVrv::DtShipFlagDirTickable::slot_coordinateSystemChanged ( )

protectedvirtual

slot for when the coordinate system changes
