Yes, but one thing you get is that any standard XML editor (and more are
arriving each day) can do all that editing and homework for you. You'd then end
up typing less, and would be able to view your scene as a tree, move things
around, colapse and expand, etc.

I had just thrown things out quickly as an example. There'd be a little more
different if this were real XML. Here's a more extreme example. but remember it
is all handled by editors.

<sphere radius=1>
    <center>
        <vector3 x=1 y=0 z=0/>
    </center>
    <pigment>
        <color rgb='#ff00ff'/>
    </pigment>
    <rotate>
        <vector3 x=0 y=10 z=0/>
    <rotate>
</sphere>

And the editor imported what you typed and then did your preferred tab
formatting on it, of course. :-)

Oh! Okay, alright, I see now.  Well, that was why I was wondering about it.
Within POV alone (script, not hard-coded) I had to adjust for the textures
quite a bit because of overlap.  The image averaging never seems to suffer
from that due to the way it gets handled.

  Scarier is that fact that Jon A. C. has a voice on the POV-Team and I saw
his last message in reply to Phillipe D. just now.
  Fact is I have to use at least the last two major versions, namely 3.02
and 3.1, just to keep my head above water when dealing with all the scene
files I have here.  There's that ever-present danger of losing today's
compatibility for yesterdays files.
  Mostly though I'd agree vehemently about the nonprogrammer status.  I
dropped Basic when it changed to QBasic and many of my files couldn't seem
to be adapted.   Along with the fact I wasn't willing to keep subroutining
in more various ways.  I'm not entirely made of programmer stuff you know.
  The capabilities which open up with the additions of better scripting in
POV-Ray is no doubt a good thing for the right people but if it were to lose
the ease of use for average people, like Ken says, there would certainly be
a gaping crevice between the two factions.  Something which is very
difficult to comprehend clearly since the raytracing medium is so varied,
from art to scientific modeling.  To make for a less debatable subject it
might be brought up about there being potential for user friendly (gee,
that's an old saying) plug-ins and extensions to the program in which the
programming aspect remains avid as all the while a user interface keeps to a
standard of useable features.

That's news to me, as I'm sure it is to the other POV-Team members.  The 
official Team roster was just posted in povray.general within the past
few days.  You might want to go reread it.

Whew! (nothing personal Jon)
Terribly sorry to confuse others by implying Jon Cruz to be on the POV-Team.
Sincere apologies to all.  I had read both those messages just yesterday and
somehow Jon got stuck in my mind as being listed there.  Strange really
because he isn't even one of the repliers to either of those.  Maybe I've
been psyched out, or paranoia is a worse thing than I previously thought.

OK, so what does a for loop look like in this
imaginary XML povscript?  

I guess that we can simply plug-in the appropriate
editors for different groups in the XML file?
Plug-in the sphere editor, bezier editor, spline,
etc...

Whew you??? Whew me!

I just saw your first post and started scanning those recent announcements to
see if I had forgotten someone talking to me.   =-O   (me with my hair standing
up)

<loop counter=foo initial=1 final=5 step =1>

 <sphere radius=1>
   <center x=0 y=0 z=0/>
   <pigment>
     <color rgb='#ff00ff'/>
   </pigment>
   <rotate x=0 y=10 z=0/>
   <translate>
     <y>foo + 1 * 5</y>
   </translate>
 </sphere>

</loop>


Arrggggghhh! no! stop stop stop!!!
My head is exploding!

;-)

I think this little exercise is getting out of hand.

DKBTrace had a similar syntax.

OBJECT
 SPHERE

 END_SPHERE
 TEXTURE
  COLOUR RED 1 GREEN 1 BLUE 1
  PHONG 1
  DIFFUSE 0.1
  REFLECTION 0.9

POV script should be changed to a language based on LISP :-)
