DtTileData is tracked by the DtOsgEarthTerrainSourceTracker for paging out tiles and for drawing tile boundaries.

Member Enumeration Documentation

Enumerator:

DtTileData::DtTileData ( )

inline

Default constructor.

inline

Constructor.

virtual DtTileData::~DtTileData ( )

inlinevirtual

Destructor.

btVector3 DtTileData::topNE

The 8 points in geocentric required to draw the tile in the debug drawer.

btVector3 DtTileData::topNW

btVector3 DtTileData::topSE

btVector3 DtTileData::topSW

unsigned int DtTileData::lastUsed

The last time this tile was used.

Necessary for deciding which tiles to page out.

unsigned int DtTileData::numTriangles

The number of triangles this tile, and therefore its collision object, contain.

Used for estimating page out gains.

TileType DtTileData::type

Abstract notion of type so we can annotate tiles (mostly for drawing then later).
