hi,
I wander if anyone could give me a piece of code C++ to call povray and submit a
program, then get the image.
(should I download povray source or only the executable is enough?)

plateforme : Win98/PowerMac Os8.5


Thanks

I am not sure what your question is.  Do you just want to create an image
with POV-Ray?  In that case you just start the application and load or write
a scene file, as described in the tutorial(s).  You do not need to write a
program or know how to program in order to get images, all you need to do is
to supply the scene description to POV-Ray and it will generate the image
for you.

It is the opposite : I would like not to lauch povray manually, nor loading a file on
disk.
I would like my C++ program to "send" as tranparantly as possible a pov file to
povray, and "receive" the image automatically, without any manual manipulation.
(mac+win)

So what you are saying is that you would like to render an image within
a window from your own program. Which I believe the API hooks in POV-Ray
are supposed to provide this service. I don't know how to do it.

The following, while never tested, should work with the Mac version. In
order to start rendering, you can use AppleScript with a few tricks to
actually start the render automatically.  To do so, you can send a "print"
event with the file to render.  The render will auto-start with the settings
of that file or if none exists, the default settings (you can find the prefs
resource format in the official source code if you want to create/change
prefs in your application).
Now comes the catch: You won't get an event back when rendering is done.
There are several ways to solve this. I would suggest the following trick.
As output format select an uncompressed Targa image. Now, you can
pre-calculate the size of the Targa image in advance, it is a fixed header
size plus width * height * bytes per pixel (usually three or four). You can
look it either up in the POV-Ray source code or just render a few images and
do the math based on that.
Now, just make your application check every few seconds if the image file in
questions already exists (remember to delete it before starting the render
if it exists), and if it exists, check its size. If the size matches the
size you expect, the render is done. As Targa images are written on a line
by line bases, you can theoretically even get a line by line preview.

Good luck,


    Thorsten
