Hi:

My question is, what happens if you want to create let's say a random
distribution of spheres joint by a blob object. My first idea was:

blob{
do while()

and here a set of spheres

}

this doesnt seem to work. And the same holds for prisms with random vertex
and other shapes. My solution was to create a script with Fortran that
writes the whole set of random spheres and the copy/paste it to pov. My
question is, is there an easy way to do this?

#declare SD=seed(235);

blob {
 threshold .6
 #declare index=0;
 #while(index<30)
  sphere {3*<rand(SD),rand(SD),rand(SD)>,rand(SD),1}
  #declare index=index+1;
 #end
 pigment {rgb 1}
 }

i have modified script for 10000+
adding a hollow

#declare SD=seed(235);

blob {
 threshold .6
 #declare index=0;
 #while(index<1200)
  sphere {3*<rand(SD),rand(SD),rand(SD)>,rand(SD),1}
  #declare index=index+1;
 #end
 pigment {rgb 1}
 hollow
 }



cant verify for more object ...no powerfull enough

Thanks and sorry, now seems to be quite simple so I feel a bit stupid.
