Hi,

Just another experiment, posted because I have a couple of questions.

a) The code for each isosurface is:
#declare F = function { pigment { crackle form <1,0,0> color_map { [0.0 rgb
0.0 ] [1.0 rgb 1 ] } scale 1/2 }}

#declare Gloop=
    isosurface{
      function { x^2+y^3+z^2+F-1 }
      contained_by{ box { -2.1, 2.1 } }
      max_gradient 14
      accuracy 0.001
}

I notice that one of the isos has a strange line on its base. How would I
get rid of this? I already changed accuracy and max_gradient, and got rid of
many more errors, but the rendering takes too long on my p200.

b) Any idea how I could make the floor using one isosurface, rather than a
grid of many isosurfaces, as I have done here?

Thanks all,

Andy Cocker
