This is to see if it helps with shader validation complains that recently started to pop up in Chrome ANGLE (but curiously not in Firefox ANGLE).

There is checkbox for choosing whether Blender should recalculate vertex normals or whether to use normals from the data.

Using vertex normals from the data can in some cases lead to artefacts. This is probably caused by sharing of vertices across several faces (I didn't find a way how to specify vertex normals per face use of vertex; there is just API for setting normals to vertices).

If you select "recalculate vertex normals" (default), this sets faces to use smooth shading, which upon subsequent mesh update computes correct vertex normals (but it will lose eventual smoothing groups baked in vertex normals).

It doesn't have effect there anyway as scene is rendered to FBO without multisampling.

Turning antialiasing off here didn't have much effect on performance though (unlike for particles).

Very much work in progress, for the moment it creates just pure geometry (no normals, uvs, colors or materials).

Also fixed bug in JSONLoader in handling of face uvs.

Vertex color parameter was undefined for dummy materials.

No wonder there were premultiplied-alpha-looking issues. We were doing it ourselves :P

NormalBlending is a bit better. But it's now producing some premultiplied-alpha-looking issues still :/

Created a couple of tools for making this process less painful:

http://mrdoob.com/lab/javascript/webgl/blending/blendfuncseparate.html

Single quote property names and hex numbers are not valid in JSON.

For some reason Chrome canary 12.0.713.0 doesn't have "window.WebGLRenderingContext".

Also fixed multimaterial ids list.

Also changed AdditiveBlending.

Work-in-progress.

So close yet so far. Test scene almost works, just two things are not rotated properly (which means maybe everything will need to be reworked :(

- model loader now handles "wireframe" parameter

- scene light colors are now specified via hex numbers

- scene format now includes additional parameter "urlBaseType" specifying where loader will look for included files:
    - options are "relativeToHTML" (look for files under HTML url http://example.com/mydemo/index.html)
      and "relativeToScene" (look for files under url from where scene was loaded http://example.com/assets/myscene/scene.js)

Simplified JSONLoader.

Updated build script.

WebGLRenderer: Made material program sharing a bit simpler/efficient. API still not good for this, but works.

Change blending method on shadow polygons. Updated example to use Lambert material and only one shadow casting directional light.

This one doesn't touch height, just centers model in X and Z axis.
