Hello. I thought a simple pattern iterator would be cool. Ive been trying to
make this for a while. Basically I want to copy a function many times and have
control over the omega and roughness.  I'm sure its a really simple thing but
I'm not that good at programing yet. I think I know that I should have each
octave added less ,but I can't keep it from getting too dim or bright.
this is what I have so far:


I might also try an averaged pigmentloop that might be easier.



#macro iterator(pigment_function_booleon,Function,Octaves,Omega,rough)
 (

#for(i,.1,Octaves,1)
Function(x*(i+Omega)+i,y*(i+Omega),z*(i+Omega)).grey/(i*rough)+
#end
0)/Octaves/(i*rough)
#end

#declare no_wrap=function(x) {max(min(x,1),0)}

camera{location<0,0,-5>
look_at 0}
 #declare ridge=function{pigment{bozo scale .1 triangle_wave  color_map{[0 rgb
0][1 rgb 1]}}}
 #declare ridged=function{iterator(yes,ridge,4,.5,.1) }

plane{z,0
pigment{function{no_wrap(ridged(x,y,z))}color_map{[0 rgb 0][1 rgb
1]}}finish{emission 1}}


thanks in advanced

Here's my average iterator it seems to work okay but it has arbitrary values and
has issues.

#macro iterator(pigment_function_booleon,Function,Octaves,Omega,rough)

pigment{average pigment_map{
#for(i,.1,Octaves,1)
   #if(pigment_function_booleon)
[pow(.5(i*rough)) function{Function(x,y,z).grey}scale 1/(i*(Omega)) ]
    #else
[pow(1,(i*rough)) function{Function(x,y,z)}scale pow(i,Omega)  translate
i*Omega]
#end
#end
}}#end
#declare no_wrap=function(x) {max(min(x,1),0)}

camera{location<0,0,-5>
look_at 0}
 #declare ridge=function{pigment{bozo scale .1 triangle_wave  color_map{[0 rgb
0][1 rgb 1]}}}
 #declare ridged=function{iterator(yes,ridge,6,.6,3) }

plane{z,0
pigment{function{no_wrap(ridged(x,y,z).grey)-.1}color_map{[0 rgb 0][1 rgb
1]}}finish{emission 1}}

Well done, you have made a good and useful macro, I play with it and 
some others pigments.
