|
* This TerraPage loader was re-written in a fashion to use PagedLOD
|
|
* to manage paging entirely, also includes a version of Terrex's smart mesh
|
|
* adapted to work with PagedLOD. The essential code by Boris Bralo is still present,
|
|
* slight modified.

* Ported to PagedLOD technology by Trajce Nikolov (Nick) & Robert Osfield
