Description
This is an ice cube i have been developing in povray, maybe someday ill make a glass of water for it.

It was done in povray, it is a superelipsoid isosurface with a negative noise3d applied, than i made it transparent, gave it an interior and added caustics then rendered.
you can get povray for free at [link]

I'd have just done it the cheap way and used the 'pillow surface', but it looks really cool with the caustics.
Although, are you using water's IOR, or 1.5?
(And please let me know if you don't enjoy boring technical discussions on your deviation page.

I was using IGlass which is 1.5. Here is the actual object, I would like to see yours as well.
isosurface {
function { -f_superellipsoid(x, y, z, 0.3, 0.3) - f_noise3d(x*2, y*2, z*2) * 0.1 }
contained_by { box { -2, 2 } }
texture { T_Glass3 }
interior { I_Glass dispersion 1.05 caustics 1.02}
finish { F_Glass1 }
translate <0,0.5,0>
rotate <0,30,0>
// photon block for an object

I haven't gotten around to implementing any ice cubes, so I don't have source code for it, but it would probably look rather like that, although I tend to use pigment functions rather than f_noise3D. I haven't the faintest idea of how to make it quasi-opaque (You'll notice real ice cubes are permeated by minute cracks and holes that make them opaque in some places), and I suppose it would require blurred transparency. I wouldn't, however, use I_Glass, since that sets an ior of 1.5 (The index of refraction of glass) - You'll want to use the IOR of ice instead - 1.31, and the dispersion of water, 1.007. consts.inc includes several relevant physical constants, like the IORs and dispersion amounts of several substances.

Thanks for the input on the numbers.

No worries... keep up the interesting work.
