They are a result of some tests that Xander did on the "old" noise3d
function.  The function itself has more flaws (such as a grid pattern that
you can see if you look closely).

Actually, 0.5 should probably have been used instead of 0.48985582 and 1.0
should probably have been used instead of 1.05242.  I don't know enough
about the original function to know details, though.  The issue is that the
range of the original function was incorrect.
