Hello, All!

I'm almost done new port of povray 3.6.1 to QNX6 (with Photon window output,
etc) and I want to send patches to developers. Are any of the POVRay
developers here ? :)

Here is my POVRay 3.5 port to QNX6 screenshot:

There should not be any patches required to compile POV-Ray on a system
with a standard conforming C++ Compiler.  If you have trouble with this
it would be a good idea to ask before starting to write patches.

Note this refers to the core code, the Unix frontend might not work
without changes on some systems.

Yes. ;-)

I got numerous warnings and errors with the type casting, the most frequent
is a assignment to int from float and the similar. But need to say, that 3.5
source was nightmare as for type casting :) comparing to the 3.6.1 sources
:)

But anyway I want to port it to QNX6 ;)

I've added Photon GUI code (like X11 and SVGA code). I think it would be
nice to include it into the mainstream sources. How I can send the patches
concerning GUI for first time ? Post it here ?

Excellent :) !

These are no errors, just warnings and you can turn them off in your
compiler settings.  Patches are neither needed not a good way to avoid
those warnings.

I am not sure what you are talking about here - does it have to do
anything with photon mapping in POV-Ray?

You can post patches in povray.binaries.programming.

I'm guessing "Photon" is the name of the graphical server/library in QNX6 or
something like that. And with "GUI" he probably means the display window.

Heh :) No.

Photon is a GUI name in QNX6 OS (like X11).

Thanks :) !

Well - if it's a proprietary QNX system it will most likely not be
supported in official POV-Ray (we obviously can't support a platform we
don't use ourselves).

That's just my personal opinion of course and anyway it does not mean it
won't be useful to have it as an unofficial extension.  Of course the
use of running POV-Ray on a real time OS is limited in general.

Ok. It's sad. Because I must to port it again and again when next version of
POVRay will be released.

What's mean "an unofficial extension" ?

Why you think, that it is limited in general ? I don't think so.

No significant changes have been made to the display routines of POV-Ray
for a long time.  Any display functions that have been written in the
last years (i'd say since version 3.1) will still work with current
POV-Ray (and in fact the SVGA code has not been modified since then.

Any modification of POV-Ray that is not part of the official version.

The purpose of a real time OS is to have detailed control of task run
times (and the ability to predict them).  This is rather pointless for a
program like POV-Ray since you do not even know how many CPU cycles a
render will take before actually rendering it.
