However, this just gives me gray points in 3D space, while I want each point to have its own RGB colour. In addition, it seems like using the points/polygons paradigm is not best suited to what I am trying to achieve; all I really want to do is plot the points themselves, without the added complication of 'unseen' polygons connecting them.</div>
