Can I work on an online Ldraw program?

Three.js is MIT licensed so you're free to use it as long as you follow the license.

There's also buildinginstructions.js (another Three.js LDR loader) which we use here on LDraw.org and is public domain.

That's cool. I'll be sure to include at least part of both ThreeJS frameworks . In the mean time, I'll be working on upgrading my existing version (don't even ask, I wrote it long ago in my programming...)
