Facet provides a set of primitives that make WebGL programming easier and cleaner.
Facet is under heavy development, so the current state of documentation is less than ideal. Still, I make a serious effort to keep all the Facet demos working, and you can see them live here.
If you cloned the Facet repo, you can find the demos in the demos/
directory. Because of AJAX security restrictions, you will probably want to run
a local webserver instead of accessing the files through the file://
scheme (files in the file:/// scheme are considered all as being
different domains, to prevent malicious scripts from trolling your
hard drive). The easiest way to do this if you run any modern Unix is to
chdir to the local Facet repository and run
python -m SimpleHTTPServer 8888
Then simply point your browser at http://localhost:8888/demos.
If you want to fix a bug on Facet or extend it somehow, you'll need node.js and npm. They're used to build Facet. On Ubuntu 11.04 and later, you can say
sudo apt-get install nodejs
to get node.js, but as far as I'm aware you're on your own to install npm. On OS X, I like homebrew:
brew install node
brew install npm
After you have installed node and npm, chdir to the base facet directory and type
npm install
You should now be able to use Facet's makefile to build facet.js, facet.min.js, and data.js.
The build infrastructure of Facet is completely based on Mike Bostock's excellent d3.
