Distance geometry and geometric algebra
@article{Dress1993DistanceGA, title={Distance geometry and geometric algebra}, author={Andreas W. M. Dress and Timothy F. Havel}, journal={Foundations of Physics}, year={1993}, volume={23}, pages={1357-1374} }
As part of his program to unify linear algebra and geometry using the language of Clifford algebra, David Hestenes has constructed a (well-known) isomorphism between the conformal group and the orthogonal group of a space two dimensions higher, thus obtaining homogeneous coordinates for conformal geometry.(1) In this paper we show that this construction is the Clifford algebra analogue of a hyperbolic model of Euclidean geometry that has actually been known since Bolyai, Lobachevsky, and Gauss…

A MAPLE package is implemented, called Gibbs, for the elementary expansion and simplification of expressions in Gibbs' abstract vector algebra, and it is shown how to translate any origin-independent scalar-valued expression in the algebra into an element of the corresponding invariant ring, which is christened the Cayley-Menger ring.

By moving from a projective to a conformal representation (5d representation of 3d space), one is able to extend the range of geometrical operations that can be carried out in an efficient and elegant way.
A covariant approach to geometry using geometric algebra
