Their shader is probably based off the thickness of the wax layer. There is zero reason to simulate the actual photon travel unless you're doing ray tracing. You can get a physically accurate model based on some fairly straightforward equations in a shader.With as much respect as it deserves, I take issue with this:
They give the impression they're using real-time photonic simulation to get the effect a shader could (and almost certainly is) achieving. I have my doubts that it's as they've characterized. I'd be happy to be mistaken on this point.
