is there a way to convert pov and inc files into moray? or is there a
utility that allows one to search through pov and inc files for an
object and import it into moray? it seems to me that if moray can go
from moray to pov, it should be able to go the other way as well. does
it? how?

This functionality does not exist nor are there any utilities available
to do so. Moray exports scenes in a very well defined way. Other programs
and hand coders however do not adhere to Moray's strict syntax format.
To parse a .pov or .inc file would require a scene file parser as powerful
as the one that POV-Ray itself uses. To write such a parser just for
the benefit of importing .pov files would require an enourmous amount
of work that no one, so far, is interested in doing.

Not to volunteer or anything(or that I'd be qualified to do such a thing
anyway), but shouldn't a POV-Ray converter just be based off of POV-Ray's
code, which, since it is open source, could be used for such a purpose(or is
there something against that in the license?). So wouldn't the work just be in
writing the export module with the data already loaded by POV's parser?

But it would mean being able to convert .pov files to damn near anything
else(or as many things as you care to write it for), which seems to be a
frequently requested ability. For example, pov2rib, or
pov2anotherfileformatthateasilysupportsmathmaticalprimitiveswithouttesselation?

There has been a lot of talk lately about adding tessellation support to
POV-Ray ( for displacement mapping and related features) which would help
facilitate adding export capabilities to the program. Once the majority
of POV-Ray's primitives can be represented internaly then converting it
to an exportable 3D file format would be much easier.
There has been no official comment about this from the POV-Team and should
be considered idle chatter for now.

Hi, Alex. POV-Ray is not open source, nor is it public domain. It is
copyrighted freeware. Anyone is free to write their own parser (good
luck!) but the POV-Ray parser code may not be re-used in a third-party
program.
POV-Ray documentation (POVLEGAL.DOC) section 5.1.8:
<snip..>
"The POV-Team does not license source code for any use outside POV-Ray.
No portion of the POV-Ray source code may be incorporated into
another program unless it is clearly a custom version of POV-Ray that
includes all of the basic functions of POV-Ray."

I was told by Dave Dunn, the AOL POV-Ray Chat host, that you could append parts
of scenes (*.inc) into the Moray scene but that you couldn't work on any of it
further. Kind of a inert addition then I guess.
On the menu, Scene/Settings then Includes tab.

Thanks for clearing that up...so, if teh converter has a renderer, then its
fine?<G>

No, it's okay only if it is a modified version of POV-Ray and clearly
stated as such. IOW, someone couldn't incorporate the POV-Ray parser
code to read in a POV scene to be rendered with an unrelated scanline
renderer.

Couldn't you just disallow code theft in commercial products? That way, you'd
cultivate a greater amount of freeware programs that'd use POV-Ray's code, which
would speed along the development of such programs.
In any case, there's probably something I'm overlooking here. I'm neither a very
prolific coder nor a lawyer, so I really am not within my domain of knowlege
here.

The real issue here is that while POV-Ray is open source it is still
the property of the POV-Team. You may modify the source to make a
different version of POV-Ray, you may study the source code for your
own edification, but you may not rip out parts of the source code
to make your own program work. The source code for POV-Ray is the
intellectual property of the POV-Team which grants them the liberty
of imposing any restrictions on it they so choose including copyright
protection under the law both national and international.
