Has anybody made an attempt to write a GHX-descirption of an elastica, yet?
If you are not familiar with it, here is a JAVA applet developed at the TU Berlin.
My attempt was simply to create a 2d elastica curve. Nothing fancy and with little interaction. The file is from December 2008. The VB script is a little messy, I hope you can make some sense of it. It's not a very mathematical solution either - the script simply rotates a line using a varying centre point. This generates a bunch of points and then a polyline is created.
