I've just imported the WIS mathematics library -- an excellent
collection of mathematics routines -- onto Google Code:
http://code.google.com/p/as3mathlib/
(You'll find the Actionscript 2 version of the library at its original
site
http://members.shaw.ca/flashprogramming/wisASLibrary/wis/index.html
This library carries a BSD-ish license and includes support for
* Geometric Objects and Intersection calculations
* Integral and Differential equation calculations
* Bezier, Quadric, Polynomial, Complex, Vector and Matrix calculations
* Symbolic expression parsing
I'm converting the library to Actionscript 3 from Actionscript 2 as
time and necessity allow. (That's converting as in getting it to work,
and converting as in getting it to be object/pattern oriented). Right
now it builds without errors and only a few warnings, but I haven't
applied any of the unit tests or checked it for correctness or
compatibility.
If you see the value of updating this well-thought out collection of
functions, please get in touch and I will add you as a developer. The
code is quite modular: it will be straigforward to take modest chunks
and get them working independently. I wrote the original author and
maintainer, who responded "By all means, continue in the
evolution/integration of my library to support AS3" -- but please let
me know of any other efforts to update this code, or if a similar or
superior math library exists, so that I don't waste my time :).
