Re: [Visualpython-users] Fwd: Vpython -> define perspective.

[Bruce S. <bas...@nc...>]

It can't be done. VPython insists on the coordinate system being a
right-handed coordinate system. What you can do is have y to the
right, z up, and x coming toward you, as in the following example:

from visual import *
x = curve(pos=[(0,0,0), (1,0,0)], color=color.red)
y = curve(pos=[(0,0,0), (0,1,0)], color=color.green)
z = curve(pos=[(0,0,0), (0,0,1)], color=color.blue)
label(pos=x.pos[1], text='x')
label(pos=y.pos[1], text='y')
label(pos=z.pos[1], text='z')
scene.up = (0,0,1)
scene.forward = (-1,0,0)
