Hi,

what you think about implementing of macros directly in POV
source-code??
I don't mean every small macro, i mean the famous macros,  like the
hair-macro and the tree-macros. Theese will be much faster in the source
as an POV-macro.

It is possible? Hard to implement?

Paul

More work than it is worth, and it would break consistency with the rest 
of the POV language. If those things are added as POV features, they 
should be modified to use the correct syntax. For example, trees should 
be objects, not functions, POV keywords should all be lower-case, etc...
Also, it would be a tremendous amount of work to simply convert the more 
complex macros and includes into functions.

BTW, for a lot of my patches, I do prototyping in POV-Script and then 
use that as a base for the actual patch. The particle_system patch was 
descended from a simple particle system written in POV-Script, the 
extended blur patch I am now working on has it's algorithms being tested 
in .pov files, etc...

Also, some features were originally macros, for example, the "sgn()" 
function in MegaPOVPlus.

I thought I had a pretty good handle on what was out there.  Is there a hair
macro?  If so, where can I get it?  I don't see anything on the pov links
page.

  There may be several, but I think that Colefax's macro is one of the
most popular.
  It may be a little hard to find since it's "hidden" inside another
macro: The povray compressed mesh (PCM) macro. The hair macro is part of it.

Ah, that would explain why I couldn't find it.  Thanks.
