Hi all,
I really want to be able to write my own macros similar to Maketree and Madpipe by
Gilles Tran, but I just don't understand what's going on. I can *just about* get my
head
round a very simple macro, but when loops get involved, I'm totally lost. Maybe I'm
just
stoopid. Would it be possible for someone to put together a tutorial for me that
explains
what's going on in this kind of recursive macro, or point me in the direction of an
existing tutorial? I would be most grateful.
Oh..and yes, I have RTFM ;-)
all the best,
--

In addition to Spider's instruction,
This is also a good tutorial on looping and using macros
by Sonya Roberts: http://www.spake.org/rtimes/article/povindx.htm

Although great tutorials there (didn't realize Sonya R. had done these) I
failed to find any mention of 'macro', I would have been interested to
learn more about macros too. :(

Recursive macros were a cypher too until I found the pyramid.pov & pyramid2.pov macros
in the
povray directory. There was (is ?) also an example of a simple fractal tree made with
a
recursive macro in the isosurface patch which was the grand daddy of the MakeTree
family. I
didn't check with the latest version of this patch but it should be still there. Most
of what
I learnt on macros was obtained by reverse-engineering the clean, well-designed ones
by Chris
Colefax, John VanSickle, Margus Ramst, Steve Pigeon and many other contributors in the
povray
newsgroups.

Thanks Gilles and everybody else who replied. I agree that reverse-engineering would
be
the way to go, leading to maximum understanding of what's going on. It's just that
most if
not all of the examples I've looked at so far succeed only in confusing me. BUT...I'll
give it another go.

Perhaps I was confused,
I'm only a beginner with C programing, but as I understand it
macros are esentially the use of the keyword "define" or in the case
of pov "declare" which establish constants(I'm sure there's a
programer here that can correct my definition).
POV of course also uses the keyword "macro" which is more like a
function
(the pov docs point this out).
As far as "macro" is concerned I've searched high and low to no avail
in order to learn more about this. If you do find anything, please let
me know...

Hello Andrew.
Tony B. has a real neat little macro in povray.utilities that, in my
opinion, describes very well what's all about. The rest is just a question
of nesting carefully the pairs #macro....#end and other #while...#end & co.
For me, a macro is much like a #declare with parameters that you can pass.

That macro will serve only to confuse you, as the syntax and semantics of the
isosurface macros were not at all the same.

Oops, my mistake. Should have checked before. Since the isosurface patch is 3.1 now, I
had assumed
that the macro examples had been ported to 3.1 too and to the official macro syntax.
Obviously
there was no reason for Ryoichi Suzuki to do so. However, I did use the original D.
Skarda
algorithm (in the old macro syntax) as a basis for my first 3.1 tree macro, which was
the really
hard way to learn how to create macros.
