I have a mathematical equation and I was wondering if it is possible to
do something like put one sphere at each vlaue or something. simple
example would be y = 3x + 1 or something... and have a while loop with
values from 0 to 10 being put in. how, if possible, would I do this?

   // Begin POV code

#include "colors.inc"
#include "textures.inc"

// Your camera here

// Your lights here

#declare J = 0
#while (J < 11)
    sphere
        { <J, 3 * J + 1, 0>,  .5
            texture { pigment { color Red } normal { dents 3 } finish {
Shiny } } }
    #declare J = J + 1
#end

// End POV code

Hi Ross,

You can :

1/ define a starting point, i.e. :
#declare x=0

2/ do your loop until an end point, i.e. :
#while (x <= 10)

3/ do your calculation, i.e. :
#declare y=3*x+1

4/ define your object based on this calculation, i.e. :
sphere {<x, y, 0> 5}

5/ do something to keep x incrementing, i.e. :
#declare x=x+1

6/ close your loop :
#end

And you have it.
Hope this helps,
Al.
