Breaking the model up to chunks is important as it makes a big difference to performance. osg::Geometry itself and OpenGL can handle much larger point datasets than 10,000 points but such large dataset don't perform we'll. One has to look at the way the OpenGL fifo is filled and emptied, and how VBO data is uploaded asyncrnously to understand why this makes a big difference. Robert.
