Member Function Documentation

void vtPagedStructureLOD::Release (   )  [virtual]

Releases a node. Use this method instead of C++'s delete operator when you are done with a node. Internally, the node is reference counted so it is not deleted until all references to it are removed. Reimplemented from vtGroup.

bool vtPagedStructureLOD::TestVisible (  float  fDistance, bool  bLoad )

Parameters: fDistance  The distance in meters to check against. bLoad  If true, and this cell is within the distance, and it isn't loaded, then load it.
