iMeshFederation::getTileCentre()
Description
Queries the tile centre, or origin, for a specified tile in this federation.
Syntax
void getTileCentre(tSigned32 tileIndex, tSigned32& centreX, tSigned32& centreY) const; |
Parameters
| tileIndex | | The index of the tile within this federation to query. |
| centreX | |
The X coordinate of the tile origin.
|
| centreY | |
The Y coordinate of the tile origin.
|
Remarks
The geometry for each federation tile mesh is centred on this tile origin,
so this origin must be subtracted from 'federation world coordinates' in order to obtain a position on the tile,
and added to tile coordinates when converting back to world coordinates.
