If you are doing geometric calculations you should look at section
10.2.2, _Conformal Model of Euclidean Space_ in "Geometric Algebra for
Physicists" by Doran & Lasenby. Their methods greatly simplify the
calculation of geometric transformations and the intersections of lines,
planes, circles, and spheres. A paper "Recent Applications of Conformal
Geometric Algebra" by Lasenby (just google the title and you can
download a pdf copy) which extends some of the calculational methods to
ellipsoids.

hi all,
Do not forget PythonCAD ..
http://sourceforge.net/projects/pythoncad/
we are using sympy for all geometrical operation ..
last yeard I made an youtube video that show how to render sympy data
to PythonCAD and how to get sympy data from PythonCAD
http://www.youtube.com/watch?v=FnxRDj4qyc4 (Watch in hd)
I will have a talk at europython2011 in Florance and of course I will
talk about sympy:

When I started studying a few years back, the only OSS we used was
Octave. Nowadays, students are taught SAGE among others. Even if
student
licences are affordable, I don't think closed source programs are
appropriate in academia and teaching.
I think this sort of evangelism is one way of getting the sympy
userbase to grow.
I've been name-dropping SymPy at every opportunity lately. :)

Alan MacDonald of Luther College has written and undergraduate
textbook
"Linear and Geometric Algebra" that uses
sympy as an integral part of solution of the study problems. See -
http://faculty.luther.edu/~macdonal/laga/
That's pretty cool. Does he just use the GA module, or the core
sympy too?
Aaron Meurer
He uses the matrix module also.
