getNumberOfGroundTilesOverlapped

Returns the number of ground tiles overlapped by the represented region for a given federation tile.

int32_t getNumberOfGroundTilesOverlapped(int32_t tileIndex, const iSourceTiling& tiling) const;

	tileIndex		The index of a federation tile.
	tiling		An iSourceTiling object defining the position and placement of ground tiles.

The number of ground tiles overlapped by the specified tile's represented region.

This method is called by the client application prior to calling iMeshFederation::getGroundTilesOverlapped(), so that a suitably sized buffer can be prepared.

int getNumberOfGroundTilesOverlapped(int tileIndex, SourceTiling tiling);
