While I fully agree with this, you might find you'll have a hard time
convincing other people of this. Many people are so locked into the
traditional concepts of linear algebra that a geometric library without
matrices (to put it bluntly) won't be very useful to many people.

If, and only if, people agree that Geometric (or Clifford) Algebra is the
way to go, then my library might be a good starting point. I am still
working on a few issues and adding new functionality (most notably
compile-time versions of the Clifford operators for gradelists, so I can put
a proper operator overloading scheme in place), but the benchmarks I have
done so far prove that my library is the fastest of the few Geometric
Algebra libraries around. One of the things I've done is port the raytracer
(http://carol.wins.uva.nl/~fontijne/raytracer/) made by Daniel Fontijne, and
used as a benchmark for Gaigen and Clu.

I will be releasing a paper with all the details somewhere about 6 weeks
from now. I originally planned to have it done before that, but my work is
taking up too much time at the moment.

If anybody has any questions about my library, I would be glad to help out.
I'm using it a lot myself and it has been very useful so far.

Cheers,
