Hi all.

I'd like to know if i can execute povray from a command line and make it
exit when the image was rendered, just like the sample after install it
(without the alert message).

I mean, I launch Pov from a Java program and i need to know when it finished
to continue the program. I do it in Windows XP with Pov 3.6 and Pov 3.1

The problem is that when Pov finish the render it still is active, the main
window, and the Java program does not continue.

I search the docs for any command line option but didnt find anything. Does
anybody know how to do it ?. Or in other way, if i could know when the
image is rendered i could kill the pov process, but i dont know how to do
it.

Any help?. Thx anyway and excuse my english.

I don't know about a command line option for this, but in the 'Render' 
window you can go to 'On Completion' and check 'Exit POV-Ray for Windows'. 
Would this help?

"/Exit" on the command line closes POV-Ray when the render is complete.  
It's under "Special Command Line Options"--

You should be able to set up POV to /EXIT

However, in DOS you can kill POV with
taskkill /f /im pvengine.exe /t
I think in Java you need to spawn a runtime
thread to make a system call, then monitor
it for completion, and kill the thread when it's
done.

Right in Java i do something like:

Runtime r = Runtime.getRuntime() // gets the current runtime
Process p = r.exec("pvengine -isample.pov -osample.png"); // Execute pov ray
and return the associated process
p.waitFor(); // Waits the current thread until povray finished

But Povray renders the image and is still open. So the thread is still
stopped at p.waitFor() When i close the window manually the program
continues.

I think the best is to set up the "Exit when done" option but still didnt
had time to try it.

In Windows:
Start POV-Ray.
In the menu, select "Renderer".
Go down to the "On Completion..." item.
In the sub-menu, select "Exit POV-Ray for Windows". It default to "Do nothing".
Exit POV-Ray.
You're done.

As has been suggested before just add "/exit" to the command line options... 
Then it will render and exit when done...you waitFor() will then continue.

I'll try when i can ... The goal of this is to integrate POV-Ray with a
basic J2EE application.

I mean. I want to make a Servlet that get data from a web form. Then I'll
create some "povray files" with that data, and launch Pov to generate a
"dinamic image". Once the image is completed the servlet would serialize
the image with its correct mime/type.

And here we have a dinamic image generated with Pov.

I cant use it now. I had Pov 3.6 correctly installed and after some
programming it doesn't work, even reinstalling doesn't start. I get the
main drawing and the message "Windows detected a problem in this program
and must be closed".

Anyway I have not much time for it, but I'll be alert ...

Thx.
