Hello!
I'm releasing an extraction from an application I'm currently working
on. It's a small library for dealing with points and polygons, called
Polygons. It really just implements some textbook algorithms w/
Prototype-style JavaScript classes. Check it out here:
http://polygons.mdaines.com/
The demo on that page (Firefox/Safari only right now) uses the point-
in-polygon function and a little trickery (nothing too involved,
though) to make dragging non-rectangular objects way more natural. In
the application I'm working on, I combine that with the rotation
functions.
I don't plan to include anything for drawing, but hey, look at this:
http://brevity.org/code/google/draw.html
Keep in mind that this is a skittish 0.1 release. I haven't tested it
at all yet with IE, and some of the syntax for dealing with Points
and Polygons needs to be ironed out a bit.
I hope someone finds it useful!
