[Visualpython-users] scene width in "real" units

[Joe H. <hea...@gm...>]

Is there a way, e.g. a function, to return the width of a VPython scene in
real life units independent of what's displayed in the scene? For example,
if I'm modeling Sun and Earth and I have them on opposite sides of a scene,
can I obtain the scene's width (~ 1.5e11 m) with a function call?
scene.width gives the width in pixels. I'm trying to take the drudgery out
of manually calculating scale factors for displaying arrows.
