OpenCTM mesh format looks quite promising, smaller than UTF8 and more robust, just geometry creation time is slower (decompression is done in JavaScript as opposed to piggybacking on built-in http gzip).

As per Giles recommendation here http://learningwebgl.com/blog/?p=4379

Also added nicer flare texture.

UV mapping of extruded geometry was miscalculated.

- ExtrudeGeometry was documented to take a Three.Material for the
  "material" and "extrudeMaterial" parameters, but the examples and
  usage in TextGeometry showed that these were in fact indices into
  the materials array. This meant that the tests such as "if (material)"
  would evaluate to false if the index passed in was 0 (a very typical
  index to choose :). Simply have the tests check against undefined and
  update the documentation.

- Also, the code that converted a shape into a set of triangles was
  miscalculating the UV offsets. It was correctly dividing the UV by
  the bounding box of the old shape, but was forgetting to offset the
  value from the minimum (which potentially led to negative UVs).

Doing normalization of normals / binormals / tangents in fragment shader instead of vertex shader. This seems to help with artefacts appearing in certain models with OpenGL rendering backend.

Also added modulating environment reflection by specular map.

Implemented again @ekitson's improvement to GeometyUrils.center. Increased light intensity in loader_json_blender example.

Turns out it may be useful after all, seems some GPUs may have troubles dealing with texture coordinates outside of <0,1> (need to be tested if normalization helps there).

Added option to ColladaLoader to recenter all Geometry so that they are centered around the local origin of their containing Mesh.

As per discussion here:

Is not used so much anymore so we can have it with a less obfuscating syntax.

This is optional, for now by default it's off, like it was before. It's up to application to update geometry bounding sphere if vertex positions change (like for meshes).
