Detailed Description
Perforce JViews Maps : This code sample illustrates how load on demand can be used when working with non reprojecting data, where the objects can be placed in a set of tiles that form a grid.
In a more general case, it is better to work with IlvFreeTile
, where tiles can be overlapping after a projection is applied.
