Here is an example of setting up an lod core with a center and a range. You would also need to add children for the 4 LODs.
00001 DistanceLOD lod = DistanceLOD::create(); 00002 00003 // this is supposed to be the center of the LOD model, 00004 // that is, this is the point the distance is measured from 00005 lod->setCenter(12,1,5); 00006 // now we add the distances when models will change 00007 lod->editMFRange()->push_back(6.0); 00008 lod->editMFRange()->push_back(12.0); 00009 lod->editMFRange()->push_back(24.0);
