Every one knows the file types pov, inc, ini. I've have a few 'in house' types I
use for POV, prm & pol for prisms & polygon for example. I know the POV team has
some they prefer but I can find any reference to them in the help file.
 What I'm doing is writing a conversion program for Misfit Modeler and I would
like to convert its models into a mesh2 pov form. What structure and type should
I use?

I have no idea what you're talking about; there is no such thing as a
dedicated file type for POV-Ray prisms and polygons. It's all plain old
POV-Ray SDL (POV-Ray Scene Description Language) files, using the ".pov"
and ".inc" extension depending on whether they're supposed to be the
main scene file or to be included by that main scene file.

You /can/ of course use your own file /extensions/, but that doesn't
make them a different file /type/. It'll still be POV-Ray SDL.

(The .ini files are a different matter; they do use an entirely
different format, but they also contain data of an entirely different kind.)

If it generates entire scenes, use ".pov". If it generates only objects,
use ".inc". In either case, use POV-Ray SDL format and the "mesh2"
primitive.

povwin also likes .mac and .mcr as extensions, which are, of course, 
just SDL by a different name.

I'VE HAVE for my use! I made a windows program to make them.

 I use the word 'type' to mean 'file /extensions' I don't like to type:)

Let's face it all these files are plain old txt files formated to what you need.

That's what I was looking for. I wanted to know what would be helpful to you!

But I thought POV team encouraged people to use .mac or something like that for
marcos.

It may save you time to type, but it will not particularly help in
conveying what you actually mean.

By extension, you're saying that HTML files are also "plain old text files".

That's not entirely accurate though: While it is true that any POV-Ray
SDL file, any HTML file, any CSV file and what-have-you-not all qualify
as plain old text files, the vast majority of plain old text files do
/not/ qualify as POV-Ray SDL files, HTML files and/or CSV files. So they
are /special cases/ of plain old text files, and therefore do constitute
file types of their own. Your statement is a bit like saying that
chicken are "plain old dinosaurs"; yes, technically they are, but at the
same time they're a species in their own right.

Nope; never heard of those for ages, and those extensions are not
actively encouraged. As a matter of fact I didn't even know POV-Ray for
Windows had any particular support for those extensions, until Dirk
mentioned it just now and I searched through the source code in an
(obviously failed) attempt to prove him wrong.

It's certainly a legacy thing. Besides the Windows editor file open
dialog, there is no reference to "mcr" as a file extension in the entire
POV-Ray project, and as for "mac" I didn't bother to investigate because
the word pops up much more frequently for probably obvious reasons.

Don't get me wrong I like "plain old text files" our civilization is built on
them. Any time I come across a file extension I'm not familiar with I open it up
with notepad. That can tell you lot about the program its meant for is
structured. Even if all you get is junk.(binary) I like chicken, I wonder how
dinosaurs taste.

I knew I remember something along lines from a long time ago. I never use it.
And I don't blame the team for dropping it. Just think if you decided to have a
file extension for every object type or function. Kayos!

That is interesting and I am surprised. I generally use .mcr for macros, 
with the impression that this was a POV-Ray team suggestion. It 
certainly did not exist or was used before version 3.6, iirc. I don't 
know who started its use then in a "formal" way.

Chris Colefax made some .mcr files in the stuff he made IIRC.

That is correct. So, at least, 1999! ;-)

Macros were introduced in Ver 3

But there is no "Save as *.mcr etc"

Nor is there a "Save as *.mcr etc" in 3.5.
