three.js support

[dav-m85]

For those interested, I just finished an example with three.js, looks like it is compatible. I haven't dug in more advanced examples yet.

Yes it is compatible. I haven't tested with the latest version though but I had no issue even with some complex demos and it runs way faster than in browsers.

Thanks @dav-m85

It would be really awesome to include this example in node-webgl. It seems to work out of the box with the version of threejs (r75 at the moment) that you can install using npm. The only issue is that that version doesn't have #ifdefs for highp in the shaders.

I could open a pull request, but the example is pretty specific, so I'll let this to the good judgment of @mikeseven :) Happy to provide support if necessary.

I just removed the precision qualifier to try and get it working but I get an exception thrown by webgl.cc in line 58. I see there's a block of code commented out. I tried uncommenting it but the method doesn't exist anymore. Any ideas?

It happens when three.js tries to set a uniform3fv

@dav-m85 I run your example and happen an error:

This is the message, I can't solve it... please tell me the reason and how to do = = ?

It seems I need to update for the latest version of threejs....
