Not sure what you're looking for in VPython that isn't already there.
Points can already be expressed as small spheres (and there's a "points"
object in the beta version, Visual 4), spheres are of course available,
and a line is just a two-point curve object (or a thin cylinder). Maybe
it is "plane" that is missing? You can make a plane either as a thin box
object, or using the faces object.
Can you be more specific about your needs?
