[Visualpython-users] nonuniformity

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

Do you ever set scene.uniform to False (0)?

Do you ever set scene.range to have different values for x, y, and z?

I very much need to hear how you use these little-used capabilities of 
VPython, as there are some cleanups that should be made to these 
facilities, and how corrections are made may be influenced by the ways 
in which people have found nonuniformity useful (or not).

The only place I know of where this machinery is used in a major way is 
in the graph module. But it is purely two-dimensional, where 
nonuniformity isn't particularly problematic. In 3D, drawing something 
as simple as an arrow is highly problematic, because you might want to 
position the tail of the arrow based on nonuniform x,y,z scale factors, 
but you want an arrowhead that looks nice, not horribly distorted.
