Return the last intersect id which touch this tile.
Implements DtTileData.
|
virtual |
Update last intersect id.
Implements DtTileData.
|
virtual |
Activate this tile (i.e a subregion) of this tile.
This complexity is b/c sometimes tiles are only valid for a portion of their extent since there is higher resolution data available for certain subtiles. All the various subtiles (up to the max lod) have to be checked and only once we are sure there is no higher res data can we use that region in this tile.
Implements DtTileData.
|
virtual |
Should be called to enable a tilekey subarea once everything else needed for it is setup.
This would be do automatically in addActiveTileKey but that function needs to be called before the masks and skirt geometry are dealt with in order to reject multiple page ins. The area can only be enabled after that is all done though, otherwise there might be some intersections done on the masked out area b/c it is not setup yet.
Implements DtTileData.
Returns true if the point is inside a valid area.
Invalid areas are areas which are covered by a mask (i.e. an cut in), have higher resolution elevation data, or have not been checked for higher resolution data yet. Does not use mask tolerance.
Reimplemented from DtTileData.

virtual |
Returns true if the extent is entirely inside a valid area (doesn't intersect any invalid areas).
Invalid areas are areas which are covered by a mask (i.e. an cut in), have higher resolution elevation data, or have not been checked for higher resolution data yet. Coordinates are triangle indices.
Reimplemented from DtTileData.
|
virtual |
Returns true if the extent is entirely outside the valid area.
This means that there is no data to intersect with in this extent in this tile. This function is generally used for optimization and may return false even if the extent actually is completely outside the valid area. Coordinates are triangle indices.
