Hi all

Thanks to lots of help from you guys on here, I have now managed to write a
POVRAY file to read a greyscale tiff file and produce a height_field to
represent it in 3 dimensions.

I have written the following code:


 #include "colors.inc"
  camera {
        location <1, 2, -1.5>
    look_at <0.25, 0, 1>
    angle 30}

background { color Gray } // to make the torus easy to see

 light_source { <5, 8, -5> White}

height_field{
      tiff
      "map0001.tif"
         smooth
          texture{
          pigment{
               gradient y
               color_map{
                       [0.0 rgb <0.2,0,0>]
                       [0.5 rgb <0.5,0.2,0>]
                       [1.0 rgb <1,1,1>]
                        }
                 }
             finish{ambient .2 diffuse .8}
            }
                   scale <0,0.025,0>
       translate <0,0.5,0>
    }


I now wish to get POVRAY to automatically read a list of 1000 map####.tif files
(each one with a consecutive file number: i.e. map0001.tif, map0002.tif,
map0003.tif, etc, etc) to then produce 1000 map####.bmp files (POVRAY rendered,
of course!).

Alain has kindly given me the following code for concat, but I am now not 100 %
sure how to apply this to my POVRAY code to get me exactly what I want:

 concat("map", str(frame_number,-4,0)),".tif")

Please can somebody help me just to finish off this last bit of coding required?

Many thanks for all your help so far.
