Then the test is easy: dot (view, nodePos-cameraPos)<0 where dot (v1, v2) is the dot product of 2 vectors in other words v1.x*v2.x + v1.y*v2.y + v1.z*v2.z. WebAnd it's easy to reset: lod->setRangeMode ( osg::LOD::DISTANCE_FROM_EYE_POINT ); This mechanism should be useful if we want to load specified level of. a LOD node at some time.
