Computer Algebra and Geometric Modelling

This project developed the Geometric Algebra System (GAS), a computer algebra system written in Lisp (to run under the public-domain KCL Lisp system) specifically for solving geometrical problems, especially those encountered in geometric modelling. The project was funded by the UK's Engineering and Physical Sciences Research Council and by IBM.
