PagedCells

using makVre::DtVortexPagedTerrainProducer::PagedCells = std::unordered_map<int, PagedCell*>

Map type for storing paged cells indexed by source ID.

Constructor & Destructor Documentation

DtVortexPagedTerrainProducer()

makVre::DtVortexPagedTerrainProducer::DtVortexPagedTerrainProducer

(

)

Constructor.

Initializes a new terrain producer with default settings.

~DtVortexPagedTerrainProducer()

virtual makVre::DtVortexPagedTerrainProducer::~DtVortexPagedTerrainProducer ( )

overridevirtual

Destructor.

Cleans up terrain cells and resources.

Member Function Documentation

preStep()

virtual void makVre::DtVortexPagedTerrainProducer::preStep ( )

overridevirtual

Performs pre-step operations.

Gets collision geometries of parts, maps terrain requests, and sets request priorities before stepping. Also manages the PagedCells being tracked.

insertTerrain() [1/2]

void makVre::DtVortexPagedTerrainProducer::insertTerrain	(	int	sourceId,
		int	requestId,
		VxMath::BoundingBox	requestBounds,
		Vx::VxCollisionGeometry *	cg )

Inserts terrain with new collision geometry.

Adds the specified parts and collision geometries to the area of a given request with the received source ID. Use when the terrain element is not already present. Also inserts this into the myPagedCells map.

Parameters

sourceId	Source ID to link this collision geometry to
requestId	Request ID to link this collision geometry to
requestBounds	Request bounds of this terrain request
cg	Collision geometry to insert

insertTerrain() [2/2]

void makVre::DtVortexPagedTerrainProducer::insertTerrain	(	int	sourceId,
		int	requestId )

Inserts terrain with existing source ID.

Calls default insertTerrain where a request ID shares the same source ID as another request.

Parameters

sourceId	Source ID to link this collision geometry to
requestId	Request ID to link this collision geometry to

getPagedCellForSourceID()

PagedCell * makVre::DtVortexPagedTerrainProducer::getPagedCellForSourceID

(

int

sourceId

)

Gets the paged cell for a source ID.

Parameters

sourceId

The source ID to look up

Returns

Pointer to the paged cell, or nullptr if not found

getPagedCells()

PagedCells makVre::DtVortexPagedTerrainProducer::getPagedCells

(

)

Gets all paged cells.

Returns

Map of all paged cells indexed by source ID

getAllCollisionGeometries()

virtual std::vector< Vx::VxCollisionGeometry * > makVre::DtVortexPagedTerrainProducer::getAllCollisionGeometries ( )

virtual

Gets all collision geometries.

Returns

Vector of all collision geometries in the terrain

isTerrainAvailable()

bool makVre::DtVortexPagedTerrainProducer::isTerrainAvailable

(

const VxMath::Vector3 &

inputCords

)

Checks if terrain is available below coordinates.

Parameters

inputCords

Position to check for terrain

Returns

True if terrain exists below the coordinates, false otherwise

setTerrainCellSize()

void makVre::DtVortexPagedTerrainProducer::setTerrainCellSize

(

double

cellSize

)

Sets the terrain cell size.

Parameters

cellSize

The new cell size in meters

getTerrainCellSize()

double makVre::DtVortexPagedTerrainProducer::getTerrainCellSize

(

)

const

Gets the terrain cell size.

Returns

The current cell size in meters

_initialize()

virtual void makVre::DtVortexPagedTerrainProducer::_initialize ( )

overrideprotectedvirtual

Initializes the paged terrain producer.

Internal method called during initialization.
