Modeling of Fresnel effects requires more sophisticted (and computationally
expensive) lighting and material models. It would certainly be possible to
add support for this in a browser and to use the extension mechanism to add
the needed nodes to specify the lights and materials.

There was a paper on ray tracing relativistic scenes in a defunct graphics
journal called Pixel. Fun stuff but not used very often.
