This spot of Perl code calculates various mathematical paths through a 2-D X,Y plane.

The sig files are Gnu PG ascii armoured signatures generated from my key. There's a SIGNATURE file inside the .tar.gz for cpansign too. Older sources can be found at backpan.


There's no drawing in Math-PlanePath, just coordinate calculations (see math-image for drawing), but here's some samples. Click each for its section in the gallery (PNG format images, about 334k total).

And in the separate Math-PlanePath-Toothpick distribution.

See math-image to display various values on these these paths.
