As my last message indicated, I'm working on macros in Pov's SDL.  Its hard
for me to concentrate so much on PovRay because of the time spent doing
everything else in my life, but now and again I find enough time to play.
So this is an example of my endeavors in macro writing - a simple stud wall
macro, with the option to specify an opening for a door.  This image is
with, the second without.  I'll also post the macro, as messy as the day I
got it to work.  :)

This is the image without the door.  Very simple; nothing there but studs.
Figuring out how to place them was fun, even though its only one simple
loop for everything but the edge studs.  I -am- learning...

Lastly, this is the .inc file that contains the macro.  Again, nothing huge,
but it was fun to figure it out.  This is just the start for me, too, so
I'm excited by how this all turned out.

Is there a reason you use #declares inside the macro instead of #locals?

Looks good, are you planning to build a whole house this way?  That would
look pretty neat.  I was thinking myself about doing this, but with bricks
(we use those here in the UK :-), and trying to figure out some sort of
"house description language" that the macro could read.

Because I don't know what I'm doing?  It never occurred to me to use #locals
instead.  Is there a specific reason why you WOULD use #locals?  Hmm, maybe
I should just read the documentation.

I think it'd be neat to make a house out of this macro, but I'm not close to
that point, yet.  Thanks for the compliment.

If you're willing to step outside of POV-SDL for your macros, check out 
"lome" on sourceforge. That's what I did, with (non-POV) macros for 
castles, but you could easily change things to generate bricked houses 
or whatever. (To be precise, they're non-POV macros that translate into 
POV-SDL to be rendered, along with HTML to show the resulting images and 
scripts to invoke POV and such.)

#local are private to the macro or file where they are defined.
#declare are GLOBAL
If you use #local in a macro with the same name used by a #declare, it will take the
place of the 
global only inside the macro. Once you exit the macro, the #local don't exist anymore
and the 
original #declare is visible again, intact.

I have house macros .. the walls are in an include .. you've inspired me 
to create a replacement include that outputs studs .. :)
