>> I don't think this group should be trying to blaze the trail with new shader languages. We actually considered that in WebGL and decided instead to support a very strict version of GLSL ES 1.0. To make all this work with HLSL (via the translators in ANGLE) we tightened up a few requirements of the underlying system. As GLSL ES progresses with more of the desktop functionality, we can rev the WebGL spec. So I think you should consider the shading language a solved problem.

And making GLSL as the only shading language for 3D in Web couples it tightly with rasterization rendering techniques. This was already a big problem with VRML and X3D, when we wanted to connect it with our real time ray tracer.

Experiments and science are wonderful things. But this is engineering, and our work has to work on a wide variety of hardware and OS configurations. One day non-rasterization rendering techniques might be mainstream. But that day is not today.
