Re: [Visualpython-users] scaling in vpython

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

a) The issue is that you changed the window from being square to being
rectangular, in which case Visual applies your specified range to the
longest dimension. For example, when you make your window wide and short
(not tall), the horizontal range is indeed 800 as your specified, but that
means that the vertical range is less than 800. It's not clear to me what
Visual's rule should be, but certainly you'll have a problem if you depend
on a square window but then make it rectangular.

b) There is no way to control the rendering. Can you say what problem you're
trying to address?
