How can I run a batch file that will automatically render POVray scene
files?

Is there a way to do it something like this?

for(i=0; i<256; i++) {

    render_file( "scene" + i + ".pov" );

}


Thanks in advance !!

Ron

You should at least tell us which operating system you plan to be doing this
on...

I'm sorry, I forgot to do that.

I'm using WinNT4.0, and I'd like to  perform this repetitive batch loop
either in a java program or perhaps even in POVray's own language using
POVray itself.

Is this possible?

Ron

In Java it should be easy. Something like this:

public static void main(String[] args)
{
    int firstFrame = ???;            // set first
    int lastFrame = ???;             // and last frame here
    String pathToYourPOV = ???;      // set your path here
    String yourPOVArguments = ???;   // set your render-args here
    String yourPOVFile = ???;        // set the name of the scenefile here,

    for (int i = firstFrame; i <= lastFrame; i++) {
        String povArgString = pathToYourPOV +
                              "pvengine.exe +I" +
                              yourPOVFile + i + ".pov" +
                              yourPOVArguments;
        Process pov = Runtime.getRuntime().exec(povArgString);
        try {
            pov.waitFor();
        }
        catch (Exception) {
            System.out.println("Something went wrong!");
            break;
        }
    }
}

The scenefile name should be the name without the frame-number and the
".pov" extension, of course.
You should also choose render arguments that make POV-Ray close itself after
rendering, otherwise you will have to close it manually or "waitFor()" will
wait forever ;-)

Greetings,
Johannes.

  Sure.  There was a thread here some time ago about image-mapping a
different image file at each frame of an animation.  You can reuse
this to include a different *.pov file at each frame.

  If you want a working example let me know as I was the one
that needed help in that thread and got it to work in an easy
and straight forward manner.

Here it is again

#declare BaseName = "foo"
#declare Extension = ".pov"
#declare NameDigits = 8-strlen(BaseName); // or just put a number in
here for how many digits after the name
#declare LastFrame = 20;
#declare FirstFrame = 1;
#declare Frame = clock * (LastFrame-FirstFrame) + FirstFrame;
#declare FileName = concat( BaseName, str(Frame,-NameDigits,0),
Extension )


FileName will have values such as foo00001.pov, foo00002.pov etc.

Cheers, PoD

It should be possible to do it in NT Batch language too.  Just a
thought.
