I have posted a version of the Spline Macro System and Tutorial on my site:

   http://www.geocities.com/ccolefax/spline

As I have mentioned on the newsgroups previously, the macro file is a big
improvement on the limitations of my Spline Include File, and includes all
of the features that have been suggested to me over the years.  The online
tutorial covers spline creation, object creation, and spline animation,
although I still want to work on the second two areas before finalising the
file.  All suggestions regarding features, documentation, and examples will
be greatly appreciated!

It looks wonderful (regardless of the fact that it's not a surprise that
it looks wonderful... :) ).

All hail the Colefax! :)

That's just excellent! Can think of many a use for this one. Personally, I
cannot understand that it's possible to make such a macro; it's almost like
a new object class for PovRay!

Simen.

Hi Chris

I've been fooling around with your spline macro, and I must say it is a very
capable inc. Makes one think why some of the more important (and parser
unfriendly) features aren't in the binary.  Don't get me wrong - your macro
performs excellent. Only one comment on your code: I see you're writing
persistance, but that's probably a down under-thing..?

Regards,
Sigmund

Of course, SuperPOV and MegaPOV both include the patch for user declared
spline paths.  My specific aim, though, was *not* to simply provide the same
functionality for the official version - macros can be very powerful, and I
would have to say that sometimes they are a better choice all 'round than
modifying the binary.

As for the persistent variables - the main use is to give users the ability
to use named macro arguments.  Yes, it's a hack - but I think it works
pretty well!  In other places I did have to change some #local commands,
because certain versions of POV-Ray don't properly support locally declaring
a variable when there is a higher level variable of the same name, but
different type.

I agree with everybody else that it's a fantastic include file, but I still
think that spline objects twist in strange ways although no twisting is
specified...!
And animated objects suddenly flip 180 degrees if you try to fly them in a
loop or similar.

But you already know what I mean... :-)
