Hello

I have a Problem reading some density files in a while loop.

The povray script should do following:

1. read a density file (e.g. tempn1.df3) and render a pictures, which is
stored as a tga or so.
2. read the next density file (e.g. tempn2.df3) adn do the same as before

3. loop it

I don't know how you can give a loopvariable in while for a filename.
....
density {
         density_file df3 "test1.df3"
   interpolate 1
   color_map {
      [0.00 rgb <0,0,0>]
   [0.40 rgb <0 0 1>]
      [0.50 rgb <0,1,0>]
   [0.60 rgb <1,0,0>]
      [1.00 rgb <1,0,0>]
   }
  }
....

How can I make test1.df3 to testx.df3, whereas x means x=1...n

Thank you very much for Your apprecaited help.

Wolfgang

  You can't render pictures in a while-loop. You use POV-Ray's animation
rendering options and use the 'clock' or 'frame_number' variables (in your
case the latter is probably easier) to do the job.

density {
         density_file df3 concat("test", std(frame_number, 0, 0), ".df3")
