Hi all, follows is a recent conversation with Jakob Flierl concerneing a
port of PVMPOV to windows, as you will see from his email at the bottom,
most of the required parts of a windows port are in place.

so if there are any programmers in here who fancy a project (and making a
lot of ppl very happy!)

Rick

-----

unfortunately I am not the person to undertake that venture, unfortunately
my programming skills extend as far as VB..

it sounds like the bulk of the work required is already in place, and all
that's needed it a skilled win32 programmer to take the project up.

I will post this conversation to the povray NG's and see if I can generate
some interest :)

I would much rather see Povray implemented with threads.  I would not
know the scope of that though.

It would be difficult.

What exactly do you require the programmer to do?
I might be interested & have a few weeks off now
I have msvc6sp3 & the msdn lib
but I am not extremely skilled ;-/
& only have a single cpu
The msdn lib will help me when it comes to thread functions etc.
How many people actually run win32 with multiple cpus

A small percentage of NT users who are fortunate enough to find
software that supports it.

Too bad that Windows9x doesn't support multiple processors. NT supports,
but I think that the number of NT users are an extremely small percent of
the Windows9x users.
  So I think it would be a waste of time.

yes but there is win2000, and in a few years i would suspect that even home
versions of windows will have multi cpu support, while threading may be a
good idea, at the moment it seems like a lot of work with benift for the
few.. mind you once its done, its done so to speak and it is something the
pov team are going to have to look at over the next few years.

not being a C programmer myself i am not sure, neither am i exactly sure
what state the completed sections of win32 pvmpov are at.

i don't think the povray source code is a good place to learn, i had a look
a while back when i was learning C and decided after 10 mins that there was
not a chance i was going to mess !!

> & only have a single cpu

there is no way you could develop with only one cpu / one machine, you would
be coding blind.

> The msdn lib will help me when it comes to thread functions etc.

sure mdsn is a great help, but you have to remeber - its finding the help in
there which is often half the problem! - the amont of times i have spent
several hours trawling the cd's when all i needed was a simple 'do it this
way' !!!

  Win2000 is more WinNT than Win9x. It's made more for the same uses as NT
is rather than for games and such. I think that many win9x games don't even
work in Win2000.

  Of course Linux (and other free unix systems) support multiple processors
and still there is no multithreaded povray for them.
  PVM-pov exists no more, and even when it existed it didn't work with
radiosity.
  Multithreading has also many other problems. It's more problematic than
it may sound. I wrote an entry in the VFAQ about this.

  Another thing is that since it's not made by the povteam, this version will
always be one step behind the official version.

I think I have noticed an improvement to all my 3d applications like Povray,
MegaPov, and the swarm off modeling tools I've been using. W2k is very
stable, me likey very much.
