I have been playing a bit with the Javascript mode of Processing 2.0a4. It seems that the directional lights are working with spheres (as shown in the online examples) but do not work with beginShape(QUAD_STRIPS) (works fine in standard mode but not in the Javascript export). See for example, a slightly changed version of the Toroid example:

Does anyone know whether that's a WebGL problem, a limitation of processing.js or something that I could fix in the code? Thanks a lot.
