Apologies,

I changed my google search terms and immediately found an effective
algorithm. All is well.

[sage-support] Re: Interior points of a parametric graph

2009-06-16 Thread Ethan Van Andel

I think I've found the source code for that. However, It seems that it
is a bit too deep/complex for me to use it as an effective base.
Therefore, does anyone know a good way to find points on the interior
of a figure?

The code that does this is in the matplotlib library, which is a
Python library Sage includes to do plotting.
