Hi,
  I was wondering if any of you knew how to make the following red
isosurface into something that look more like the yellow cylinder CSG? 
ie. scaling the sinusoidal shape of the isosurface, but keeping the
small radius it has.

Here's my code for the iso:

#declare a = 100;
#declare b = 25;
isosurface {
  function { a*x*x + a*y*y  + b*x*cos(z*2*pi) + b*y*sin(z*2*pi) }
  [...]
}

Thanks,
  Simon
