[osg-users] Simplifier does nothing if smoothing set false

I have experimentally determined that a Simplifier with _smoothing set to false will not accomplish anything. The number of verticies always stays the same: osgUtil::Simplifier simp; simp.setSmoothing(false); // set true to actually do something. simp.setSampleRatio(0.5);

Your DLLs need to be *in the same directory* as your executable, or the DLL's have to be someplace that can be found from your PATH environment variable. You also need the visual studio redistributable if visual studio isn't installed on the target machine. Lee On Wed, 2009-06-10 at 14:39
