This is a test of the subdivision macros (still no texture mapping yet). 
  The subdivided vertices are jittered twice after each division.  The 
first jitter in each generation is scaled by the cosine of the time 
value, and the second jitter in each generation is scaled by the sine of 
the time value.  This produces a jitter amount that has a random phase 
over the course of the cycle.

The first level jitter is at a frequency of 1/7 with an amplitude of .1, 
  and all succeeding levels are at double the frequency and three-fifths 
the amplitude.

As you may guess from the texturing, the base hull is a cube.

Regards,
John

And here was me wondering how you had textured the isosurface like that...

Great job!

Now that's cool!

I saw a poster that read:
"Simpsons: The Movie: Rent it or own it."
I'm not sure, but I think it's a threat.
