I did not think it was possible to write a proper raytracer for
arbitrary content all as a shader program, but I do not know enough
about 3D graphics to know if that demo is correct or if that is
possible in general. Point conceded though.
Neither of examples you posted seems to have the ability to zoom in,
so I don't think they show anything about doing this to extremely high
accuracy. But I see your point that much of this particular
computation can be done on the GPU, up to probably quite high limits.
Replace this example with your choice of non-data-parallel computation.
Very sexy demos, by the way.
