There is this, and a lot more ideas for coordinate geometry, in "Mathematica Graphics" by Tom Wickham-Jones (Springer 1994). Incidentally, this is one of the best Mathematica books *ever*. The code (called "ExtendGraphics") is available for free on MathSource (www.mathsource.com). -Phillip ----------------------------------+---------------------------- Dr Phillip Kent | tel +44 (0)171 594 8503 Mathematics Dept (METRIC Project)| fax +44 (0)171 594 8517 Imperial College | p.kent at ic.ac.uk London SW7 2BZ, U.K. | http://metric.ma.ic.ac.uk/ ----------------------------------+---------------------------- "We would like to have a theory of the obvious"-Andrea diSessa
