Here is an example method that writes the raster object "worldRaster" to 
 a .png file each time it is called ... it is called once per time 
step, and the file name includes the time step number (currentTime).

If you skip the "setWidget" command, it grabs the whole screen.

I use some shareware called GIF Construction Set to assemble the .png 
files into a movie. I'm sure there are other ways.

-(void) writeFrame {
  char filename[256];
  id pixID;

 sprintf(filename, "Model%03d_Frame%03ld.png", modelNumber, 
getCurrentTime());

 pixID =  [Pixmap createBegin: [self getZone]];
 [pixID  setWidget: worldRaster];
 pixID = [pixID createEnd];
 [pixID save: filename];
 [pixID drop];

}
