Member Data Documentation
| 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.
