Portolan Line Generator

[Hai-Etlik]

If you've been following my entry in the light challenge, this is a somewhat cleaned up version of the script I used to make all those lines:

To run it you'll need Ruby, and the output is SVG, so you'll need a vector editor like Inkscape to work with it.

I'm releasing it under the GPL, and I've included some alternate compass roses under CC-BY-SA.

Replying to a post in another thread:

That reminds me, I tried to use that thing myself in one of my wips but I found it had too many lines. Maybe I'm not doing something right with it but is there a way to reduce how many intersections there are on a page? For instance, if I only wanted one set of lines?

Set the -p option. The default value of 4 gives 16. Reducing it to 3 will give just 8 points around the circumcircle.

You can also eliminate the outside lines with the --range option which can be set to inner (Only lines inside), or inner90 (Only the innermost 90° at each point).

A very simple setup would be:

ruby portolan.rb -p3 --range=inner90

Well, the solution to that is: http://www.ruby-lang.org/en/downloads/

Otherwise, here's an 8 point version.

Thanks for the link. I'll be checking that out although I've never coded in Ruby.
