Hand-coded 200+176 patches?! Please tell me you're joking! I tried to
hand-code a patch object once, but failed rather miserably. Beginning to
feel inferior here...

But really, my logic is that it's inefficient to hand-code bicubics (and
triangle meshes), and I feel no shame using sPatch and mesh editors. So
consider me a man of low morals.

Partly joking.  They're generated and manipulated by a clever series
of loops and equations, but there is still a lot of hand-tuning and
so on involved, plus the need to have a feel for how the control grid
affects a patch, and the need to correlate the grids of adjacent 
patches to avoid creases.  The object with 176 patches actually
only has 4 types of patches, but there are multiple instances of
each type.  The 200-patch object has four different types of patches
in terms of what they do, but their locations are somewhat random
so the crease-avoidance factor comes into play.

Besides it says quite clearly in the Pov docs that Patches are beyond
the capabilites of most users and they recommend using an external
program to generate them for you. If the Pov docs say it's ok to do it
with an external program, then it MUST be considered acceptable, even
to a dedicated Pov snob !!!

I have never seen in the Pov docs where it is recommended that you should
indent your sript on the other hand.

The truth, as I mentioned a moment ago, is that I do generate them
with a program.  It's just that the program is written in POV-script.

Not recommended, perhaps, but from the Language Basics section...

    You may add blank lines, spaces or indentations as long as 
    you do not split any keywords or identifiers.

so it's okay to indent.  It won't hurt a bit.

Hi Andy,
As a fellow Yorkshireman turned Scot I salute you from Hamilton,
Scotland
I'm the geriatric of the group and like hand coding (indented).

Closest neighbours thus far, I believe...

Hey, even I can't complain about the temperature.  I get up at 5:30 just
about every morning and often times am on the water by 6:15, but
recently whenever I get the the boathouse it is around 45F, very
doable... especially since we don't get each other wet much anymore.

shirt and spandex shorts.  Not only an ugly picture, but pretty damned
cold)

I'd like to indulge this thread with a little bit of source taken from
the POVRay Docs

  #include "colors.inc"
  camera {
    location <0, 0, -6>
    look_at <0, 0, 0>
  }
  light_source { <-20, 30, -100> color White }
  light_source { <10, 30, -10> color White }
  light_source { <0, 30, 10> color White }
  #declare PLAIN_TEXTURE =
    // red/white check
    texture {
      pigment {
        checker
        color rgb<1.000, 0.000, 0.000>
        color rgb<1.000, 1.000, 1.000>
        scale <0.2500, 0.2500, 0.2500>
      }
    }
  // plain red/white check box
  box { <-1, -1, -1>, <1, 1, 1>
    texture {
      PLAIN_TEXTURE
    }
    translate  <-1.5, 1.2, 0>
  }

Notice the indentation?  I did not add it.  Ken, take this as implicit
recommendation to indent.  Perhaps we should ask the authors to add this
in.
