Detailed Description

Large Data Management 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.
