Detailed Description

The SRTerrain class implements Stefan Roettger's algorithm for regular-grid terrain LOD. It was adapted directly from his sample implementation and correspondence with him.

Member Function Documentation

void SRTerrain::SetPolygonTarget ( int  iCount)

Set the polygon target, which is the number of polygons (generally triangles) which the CLOD algorithm will try to maintain.

Reimplemented from vtDynTerrainGeom.
