Detailed Description

Specialisation of PageStrategyData for Grid3DPageStrategy.

Remarks
Structurally this data defines with a 3D grid of pages, with the logical origin in the center of the entire grid. The grid cells are indexed from 0 as a 'centre' slot, supporting both positive and negative values. so (0,0,0) is the centre cell, (1,0,0) is the cell to the right of the centre, (0,0,1) is the cell in front of the centre, (0,1,0) the cell above the center, etc. The maximum extent of each axis is -512 to +511, so in other words enough for over 2 billion different entries.
To limit the page load requests that are generated to a fixed region, you can set the min and max cell indexes (inclusive)for each direction; if a page request would address a cell outside this range it is ignored so you don't have the expense of checking for page data that will never exist.
The data format for this in a file is:
Grid3DPageStrategyData (Identifier 'G3DD')
[Version 1]
Name Type Description
Grid origin Vector3 World origin of the grid.
Grid cell size Vector3 The size of each cell (page) in the grid
Grid cell range (minx, maxx, miny, maxy, minz, maxz) int16 * 6 The extents of the world in cell indexes
Load radius Real The outer radius at which new pages should start loading
Hold radius Real The radius at which existing pages should be held if already loaded but not actively loaded (should be larger than Load radius)
