Hi again

I would like to know if anyone has an easy, cheap way of obtaining the screen coordinates of objects in the 3D scene. I want to draw some 2D stuff onto the canvas near certain objects when they appear on screen (I already have the drawing part figured out) but I'm having trouble getting the screen coordinates of these objects.

Also, while I'm at it, does anyone know how to get the lookat vector from the current viewingplatform transform?

Thanks guys!
