[Visualpython-users] Numpy progress

[Arthur <ajs...@op...>]

Hi folks -

I had made some commitment to try to get to a vpython that integrates 
with the numpy library accomplished.

Was traveling last week and had the opportunity to spend some time with 
it at lay-overs, etc.

Long story short -

I'm getting there - but in a round-about way, as I am not a C++ 
programmer so there is a large learning curve for what would otherwise 
be a small problem. Have a build that works for some demos but fails for 
curves and convex objects. But I think I have a beat on the problem. The 
fact is that the various numeric libraries are mostly compatible, and 
there are only limited areas where code changes are needed (mostly 
related to typing).  Just took me a while to get the lay of the land.

The issue -

The main thing that complicates following the current code is that it is 
designed to accept  either the Numeric or Numarray libraries - on the 
fly.  It also complicates the build process and makefiles,  the  Python 
code for the  start-up of  vpython, etc.
 
My opinion is that we should bite the bullet and simplify -  and have 
builds that do not try to be backward compatible with Numeric and/or 
Numeric, and are tied only to numpy.

Acceptable?
