GroupSortForQuadtree

Sorts a list of child nodes into correct order for a quadtree. This command does not actually create the quadtree. This command assumes that the child nodes are in order from bottom-to-top. The CreateTerrainFromGeographicTiles command creates nodes in this order.

Using This Command

Select a group or level-of-detail node and apply the command.

  1. Select a group or level-of-detail node.
  2. Right click and choose Sort Children For Quadtree from the listed options.
  3. The software sorts the nodes into correct order for a quadtree.

Figures

Figures are as follows:

Figure 1.1. The original hierarchy, sorted from bottom to top. The CreateTerrainFromGeographicTiles command creates the terrain in human-readable order. The first number is the column and the second number is the row. This order won't work for a quadtree but it is much easier to read and examine than quadtree order. Sorting nodes into quadtree order. Figure 1.2. The nodes on the worksheet, numbered for reference. Sorting nodes into quadtree order. Figure 1.3. The nodes sorted into quadtree order. Each quadruple-set of groups represents one quarter of the database. Sorted into quadtree order. Figure 1.4. The first quadruple set. Sorted into quadtree order. Figure 1.5. The second quadruple set. Sorted into quadtree order. Figure 1.6. The third quadruple set. Sorted into quadtree order. Figure 1.7. The fourth quadruple set. Sorted into quadtree order.
