Hi there-

I'm trying to create a 'screen' for my povray bong using tori.
At the same time I'm trying learn how to use povrays programming
directives so I do'nt have to write so many lines of code.
I'm including the code I've already written so you can see what I'm
attempting to do.

/ Persistence of Vision Ray Tracer Scene Description File
// File:screen.pov
// Vers: 3.1
// Desc: screen created with tori
// Date: 8/20/98
// Auth: ArfGrafix



// ==== Standard POV-Ray Includes ====
#include "colors.inc"	// Standard Color definitions
#include "textures.inc"	// Standard Texture definitions
#include "metals.inc"


// Set a color of the background (sky)
background { White }


camera
{
  location  <0.0 , 2.0 ,-5.0>
  look_at   <0.0 , 0.0 , 0.0>
}


// create a regular point light source
light_source
{
  0*x // light's position (translated below)
  color red 1.0  green 1.0  blue 1.0  // light's color
  translate <-20, 40, -20>
}

#declare b_ring =
  torus { 2, .0625 pigment { P_Brass3 } finish { F_MetalC }  }
 
 object { b_ring scale .9 translate .1*y }
 object { b_ring scale .8 translate .2*y }
 object { b_ring scale .7 translate .3*y }
 object { b_ring scale .6 translate .4*y }
 object { b_ring scale .5 translate .5*y }
 object { b_ring scale .4 translate .6*y }
 object { b_ring scale .3 translate .7*y }
 object { b_ring scale .2 translate .8*y }
 object { b_ring scale .1 translate .9*y }

I wrote this piece of code and soon found out that this creates a
conical series of tori...I tried making a while loop to do this, but was
flummoxed by the task of having the while do two different operations.
What I want is series of tori that form a hemisphere rather than a 
cone..that is each torus is a latitudinal strip that trace out a
hemisphere.
Thanks in advance for any helpful input that anyone may have.

Best regards,

Ron Hicks
