IMAGE DESCRIPTION: 

  A Crazy Small Robot Park where everything has an opposite,almost.
  (There are little Tobors that run around and play.)
  I could not stop at a pair of opposites. I want MORE.
  
  Black & White, Fire & Ice, male & female, order & chaos 
  are just a few of the opposites here. 
  Most the objects on the Right are opposites of the left and
  represents order in the scene.
  The Flags symbolize both life/death and chaos.     
  As you examine the scene you'll notice that even
  you have an opposite examining you from the fog. 

SCENE :
 size: 800 * 640
 antialias: threshold .1 method 2 depth 3
 radiosity: details in zip
 frame level objects: 4007


DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 


  I had fun. When your having fun time has no meaning.So the
  5 hour render time and the several other long test render
  times where easy to take.
  
 All the objects for the scene where made by me.
 
 Here is a quick list of the scene objects:
  Sky             Ground     Trees
  Brick           Benches    Robot & Tobors
  Flags & poles   Balloons    Post & Chain
  Fountain        Chess set

Here are how things where made.

Lights: For testing I use 2 lights at 
        <60,200,-300> & <-60,200,-300>  both white.
        For the finish scene I use my own hand made array
        of 60 lights between these two locations with
        there colors dimmed.
radiosity settings:
      with default ambient light =0  
      pretrace_start 0.08  pretrace_end   0.02 
      count 5              nearest_count 2 
      error_bound .8       recursion_limit 3
      low_error_factor .5  gray_threshold 0.0
      minimum_reuse 0.015  brightness .5
      adc_bailout 0.01/2   normal on
      always_sample on   
        
     Without radiosity the scene took around 20 min. to
     render. I did play around a bit with radiosity.The
     flames have ambient. I think none of the other 
     object do.


Sky: I used the average pattern with two pigments.
      One pigment was a normal sky, 
      the other was an old picture of me. 
        (here's looking at you)

Ground: This is two height feilds,really one and a copy. 
        the first has a grass pigment scaled normally and         
           place to the Right
        the Copy has the same grass pigment but is scaled
           with the x direction negative
           and placed to the left
        
   The Sidewalk: This was the main reason the height field
          was used to make the ground.I wanted the sidewalk
          lower than the grass. You'll notice that the 
          colors are different from one side to another.
          This is done by having 2 boxes placed side by side.

Trees:  There's 2, but like the Ground you have one and a copy   
         The copy uses the same scaling trick as the ground.
         The tree was made using my old POV MeshTree2 file.
           (It's not on my web site! It really should!)
        There are 2 Mesh2s that make up a tree the Tree mesh
        and the Leafs mesh.
        The Tree mesh pigment used the spherical pattern.
         The Copy Tree mesh pigment was the same except the
         color map was reversed.
        The leafs for each tree uses a solid color. By the 
        time I was working on the tree I had the wall up, so
        I choose colors for the leafs from the wall behind the
        tree.

Brick : 
  Main Brick walls: 
       This is the first thing I made when starting this scene. 
       I had a plain green plane as the ground and a blue sky.
        I use a box for each brick and a box for the mortar.
       Each brick has its own color and was rotated randomly
           before being place.
       There are 2 walls each built separately with the bricks cut
       where they meet in the middle.
       
   The Planters: 
        I had to have the planters around the trees because the 
        trees where not tall enough to get over the wall. The 
        planters where constructed similar to the main wall except
        the bricks where rotated into place and the mortar is a 
        CSG using cylinders.
        
Benches: I made a bench using a union of spheres,cyliders and a
        couple of polygons. Then again made a copy.
        
Robot & Tobors: What Are Tobors? Who knows? What would you call
          the midpoint between to opposites. That's what I called
          Tobors.
          The Robots & Tobors are really the same object just 
          colored and size and of coarse posed differently.
          A while back I was playing with animation. Trying to
          get the walk cycle down and I made this robot. I got
          that done by hand. I'd make 2 key poses and let POV
          interpret the between poses. So I made a c++ program
          that would help make those key poses. 
           While working on this scene I wanted more than just
          objects to fill the park. So I copy all the key 
          animation POV files to this project directory. With a
          little adjustment to those files I was able to pose
          and place Robots & Tobors easily.I have put those files
          in the zip along with the poses.
          
Flags & poles: Why are the Flags so long? Chaos!
              The pole is a cylinder with a spirel1 pigment.
              The ropes are a sphere spline.
              The Flags are a mesh2 based on a spline.  

Balloons: The balloons and the string holding them are from a Macro
         I wrote a while back. This is the first time I used them 
         in a project. (I really need to put some of this on my
         web page)
            
Post & Chain:The posts are a simple union of a sphere and cylinder.
             A chain's link are 2 links one inside another.With
             some transparency in the texture on the outside link.
             Yin Yang uses the spiral1 1 pattern on a squashed
             sphere. 
               
Fountain: The Fountain is made up of 2 CGS objects one inside the
          other. Both are intersection of cones. The outer one
          has a radial pigment pattern with Clear and White colors.
          The flames rest on cylinders. I made the flames before
          for an oven burner. For this project I change the colors
          and scale them a bit. 
          The ice is a cylinder with layered textures. I worked a
          good while trying to get it to look like it does. 
        
Chess set: I made this a long time ago I've use it in several IRCC
           entries. Of coarse it has movable pieces witch I moved
           for this project.                                                    
 



epilogue: 
Zip-File: OP_Park.zip should have everything to parse the scene.
         
 If what you have seen in my picture doesn't give you the feel
 of the subject 'opposite' then you should know that the
 Robots on one side are thinking and feeling todally opposite
 from their counter parts on the other side.
 One side has the vilest thoughts that you can imagine, while
 the other the purest thoughts. I let you decide which side
 is which.     
 
 My web page has some basic tools for working with POV-ray.
 All the tools are written in C++ and are for Windows.

 Feel free to E-mail me with any comments and or suggests.
 If you e-mail me make sure you have POV in the subject
 or I WILL NOT read it.
