Constructor & Destructor Documentation

makVrv::DtWindRotTickable::DtWindRotTickable	(	DtDe &	de,
		DtElementID	elementId,
		DtUniqueID	sceneObjectId,
		DtUniqueID	uniqueId,
		bool	useInstancing,
		unsigned int	nodeTypeIndex
	)

CTOR.

virtual makVrv::DtWindRotTickable::~DtWindRotTickable ( )

virtual

DTOR.

Member Function Documentation

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

virtual

Update the wind rotation for the node based on the environment.

Implements makVrv::DtTickable.

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

virtual

Configure node based on json data.
