Abstract rotorWash object updater interface.

DtDynamicTerrainObjects are distributed objects, managed by DtTickableManager. They generate Dynamic Terrain World change requests (and removals) based on events. The network dynamic terrain object maintains a list of such events. There may be multiple dynamic terrain objects (so a single one doesn't get too large). This class is the local representation of one of those network objects.

CTOR.

Parameters

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

makVrv::DtDynamicTerrainObject::DtDynamicTerrainObject ( const DtDynamicTerrainObject & copy )

makVrv::DtDynamicTerrainObject::DtDynamicTerrainObject ( )

Member Function Documentation

DtDynamicTerrainObject& makVrv::DtDynamicTerrainObject::operator= ( const DtDynamicTerrainObject & copy )

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

virtual

The update function called by DtTickableManager during update-ticks.

Parameters

[in] tNow is the current time-stamp.

Implements makVrv::DtTickable.

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

virtual

The needsUpdate 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. The base class checks handles period checks (for tickables that don't tick every frame. This derived version calls down to the base class and if true, checks the size of the DirtyList; returns true if their are items on the DirtyList

Reimplemented from makVrv::DtTickable.

DtUniqueID makVrv::DtDynamicTerrainObject::uniqueId ( ) const

inline

Returns the distributed object id of this dynamic terrain object.

virtual void makVrv::DtDynamicTerrainObject::addSphericalGeometry	(	int	index,
		const DtVector &	location,
		double	radius,
		double	priority
	)

virtual

Distributed Interface.

The class maintains a vector of geometries and associated data. By definition, once added, a geometry never goes away. This results in a DynamicTerrainSphereItem being created and added to our DynamicTerrainVector. A DtUniqueID is also generated for this item. If the spherical geometry already exists this just calls changeSphericalGeometry. If there is any other kind of geometry in the slot this call generates a warning and returns without making changes

virtual void makVrv::DtDynamicTerrainObject::addLinearGeometry	(	int	index,
		int	vtx,
		const DtVector &	location,
		double	priority,
		int	vertexCount
	)

virtual

The class maintains a vector of geometries and associated data. By definition, once added, a geometry never goes away. This results in a DynamicTerrainLineItem being created and added to our DynamicTerrainVector. If the linear geometry already exists this just calls changeLinearGeometry. If there is any other kind of geometry in the slot this call generates a warning and returns without making changes vertexCount is the number of verticies in the full linear geometry.

virtual void makVrv::DtDynamicTerrainObject::changeSphericalGeometry	(	int	index,
		const DtVector &	location,
		double	radius,
		double	priority
	)

virtual

Change the spherical geometry in the specified slot. If the slot contains non-spherical geometry, this call is ignored.

virtual void makVrv::DtDynamicTerrainObject::changeLinearGeometry	(	int	index,
		int	vtx,
		const DtVector &	location,
		double	priority,
		int	vertexCount
	)

virtual

Change the linear geometry in the specified slot. If the slot contains non-linear geometry, this call is ignored vertexCount is the number of verticies in the full linear geometry.

virtual void makVrv::DtDynamicTerrainObject::clearData ( int index )

virtual

Clear the data associated with the geometry at the specified index. This does NOT put the item on the dirty list. If the intent is to remove the item at index, call removeItem(). This is used to make it easier to make data changes by clearing and then resetting the list (using addData(), which will add it to the dirty list)

virtual void makVrv::DtDynamicTerrainObject::removeItem ( int index )

virtual

Remove a dynamic terrain item (such as a crater or persistent track) Note that we don't want to change the item/index relationship for the other items; so myDynamicTerrainVector[index]; amd its possible this same item might be recreated if this was deleted and then a scenario rewind / replay happens. So we create a remove request to the dynamic terrain system, 0 the data vector, but otherwise keep the item around. Items with 0 length data will be ignored.

virtual void makVrv::DtDynamicTerrainObject::addData	(	int	index,
		const std::string &	key,
		const std::string &	value,
		double	priority
	)

virtual

Add a data pair the the specified geometry.

virtual void makVrv::DtDynamicTerrainObject::makeDirty	(	DynamicTerrainItem *	item,
		int	index
	)

protectedvirtual

Helper functions.

Check to see if the item is already on the DirtyList; if not, put it there, otherwise do nothing

virtual DynamicTerrainItem* makVrv::DtDynamicTerrainObject::getDynamicTerrainItem ( int index )

protectedvirtual

Get the dynamic terrain item at ths specified index if it exists. Generates a warning and returns 0 if it does not.
