Detailed Description
Tile ID
Encapsulates the ID of a tile.
In the default LDM architecture, the LDM data is based on an octree topology. The index is 0 for the tile of lowest resolution representing the entire volume (octree root node). The index increments linearly going down through the octree.
Indexing works as follows:
Tile 1 is the lower back left corner of the cube. The index increments on X, then Y, and finally Z. So the back tiles are:
3 4
1 2
And the front tiles are:
7 8
5 6
The tiles of full resolution are the leaf tiles.
