[Visualpython-users] Rendering with big coordinates

Dear all,

I noticed a lack of precision in the rendering of the ellipsoid when 
going to big numbers.
I need these big numbers because I am trying to display planetary 
remote sensing illumination scenarios.
Here is the code I used to create the attached image:

from visual import *

xaxis = arrow(axis=(4000,0,0), shaftwidth=40, color=color.red)
yaxis = arrow(axis=(0,4000,0), shaftwidth=40, color=color.green)
zaxis = arrow(axis=(0,0,4000), shaftwidth=40, color=color.blue)
mars = ellipsoid(length=2*3396.19,height=2*3396.19,width=2*3376.2, 
opacity=0.5, color=(1,0.7,0.2))


As you can see the ellipsoid is very 'edgy', can this be improved somehow?

Best regards,
Michael
