Geometry package

[Justin Pearson]

Hi all,

I'm looking for a geometry package in Python; something that will let
me define line segments, and can tell me if two line segments
intersect. It would be nice if the lines could be defined in n-space
(rather than be confined to 2 or 3 dimensions), but this is not a hard
constraint. Other functionality might include support for polygons,
convex hulls, etc.

I've searched Pypi and found a package called Shapely, but when I
followed its installation instructions, it threw a bunch of errors and
tried to re-install Python .

Is there a well-known geometry package I'm missing?

Thanks for your help,
Justin

Somewhere book marked I have a reference on intersection determination. I
need to reference it myself, and will look later. In the meantime, a Google
search on robotics imaging line intersection might do the the trick. Now
that I think about it, the article was aimed at finding the minimal distance
between two lines in space. Anyway, the Google tip might get you started.

I used PythonCad for this part -- It didn't take too long to identify
and adapt those parts I needed and extract them from the gui...

I don't know if it is well known, but you could take a look at
Euclid:

The geometry support is pretty basic.
