Re: [Visualpython-users] Pygeo

[kirby u. <kir...@gm...>]

Francisco seems to have picked very recent or current versions of
everything which to me indicates he's serious about bringing Arthur's code
forward.

As Bruce points out, unless he has already gone to serious lengths to
somehow overhaul the code, it's likely to also run in a 2.7 environment
with this change to make it forward compatible:

from __future__ import division, print_function

My guess is getting Python 3.2 + Visual 5.74 working smoothly *before*
trying to run Arthur's program with those tools would be a good strategy
i.e. make sure the demos work and that you have a working Vpython
environment.

Then add Arthur's code as a package under site-packages (but I forget if it
was really that simple an architecture -- I'm pretty sure it was).

Another group you might post to about this work is ed...@py... --
that's where Arthur himself used to do a lot of posting, his writings
easily findable in the archive.

I'd say Arthur's passion was projective geometry more than Python / VPython
per se.  He looked long and hard for the tools that would enable him to
express his vision and Python / VPython was what came closest, but he was
always critical of what he perceived as shortcomings.

I see Arthur as a pioneer, going deeply into a synergy (projective geometry
+ computer programming) that relatively few have explored to date, since
both are specialized subjects and one tends to be strong in either one or
the other.

Given he was an amateur with a background in finance, I think Arthur's
being relatively "weak" in both, compared to an expert in either, is what
enabled him to take it as far as he did.  He grew strong in a new way.  A
trailblazer.
