fast and chainable matrix and vector math
Just download the package from GitHub, unpack it and link to one of the vec.js files from your pages.
You can use vec.dbg.js while writing your code; it has some basics parameter checks to ensure that you don't forget to pass arrays and that they have the right size.
Once you're done though, you should switch to vec.min.js.
It's faster, and the purpose of the debug version is mainly to find syntax errors; you don't really need to waste time testing that when you now your code runs...
Coming soon...
