how to build three.js from sources

Question

I'm having some trouble getting three.js to build - the resulting three.js file is significantly different than what I downloaded.

This is likely related to the comment "This page is currently invalid and needs to be rewritten" on this page in the wiki, ["How to generate a compressed Three"](https://github.com/mrdoob/three.js/wiki/build.py, -or-how-to-generate-a-compressed-Three.js-file).

Nonetheless, I'm a bit up a tree.

I'd like to add collision exclusion to Raycaster.js/intersectObject(), but rebuilding breaks my app without errors or warnings in the console.

I've tried with various permutations of the possible --include's, with varying but unsuccessful results.

I'm not even trying to build the minified version.

I'm on OSX.

Any pointers are appreciated.

On a terminal window go to utils/build and run:

python build.py --include common --include extras --output ../../build/three.js

Or... run the shell file:

./build.sh
