I have a series of JPEG files I exported from Adobe Premiere and I want to
use these in an animation as images on a screen within the animation. The
line I use to successfully put one image up is

#box { <0.0, 0.0, -screenthi> <screenwid, screenhei, screenthi> finish {
ambient 1 diffuse 0.9 } pigment { image_map { jpeg "filename.jpg" once
interpolate 2.0 } scale <screenwid, screenhei, screenthi> } translate
<-screenwid/2, 0, 0>}

the filenames are from train0001.jpg to train7046.jpg so I want to use the
clock to change the input file so that the code will look at the right
frame. I tried using a concatenation script however parenthesis around the
filename didn't allow that. How do I achieve this result?

instead of using concat within the filename:
image_map { jpeg concat("filename", str(filenum,0,0),".jpg")}

try predeclaring it:

#declare filnam = concat("filename", str(filenum,0,0),".jpg");
image_map {jpeg filam}

-tgq

You may need to use str(filenum,-4,0) to get the leading zeroes in
"train0001.jpg".

Appreciate the help lads, but neither of those methods worked, I put
together 1000 lines in excel the easy way and imported it into a
switch/case routine and got the desired result, but its still tedious.

  So you just dismissed them without giving them a second thought?

  Please read the help files about str() and concat() and try to
solve *why* it didn't work for you. The principle was correct, so
if it didn't work it's because you did something wrong (a typo
perhaps?), not because it's not possible.

This works most definitely (because I use it in an animation)

#declare PaintingName =
concat("art/MBclear/DK44",str(frame_number-4300,-5,0),".png");
// art/MBclear being the folder where the images are
// DK44 is the base name with the str() bit giving DK4400001.png through
// DK4410000.png

#declare ClearPainting1 =
union {
        object {PngPainting (PaintingName, 400, 225, 1 , 0, 12.5, no, < 0,0,0>)}
        object { ScrewSet }
        }

// PngPainting is a macro that scales, rotates and frames the image

// And here I place it in the scene
object { ClearPainting1 translate <  1000, 412.5, 20> }


See, no need for 1000's of lines bundled in Excel. Since I have a total of
18 of these moving paintings over a total animation of 10.000 frames that
would give me 180.000 lines of case statements. No, thank you. I like the
above a lot more

Hope this helps

It's like when the string connected to the trigger mechanism breaks at the
wrong time and you find yourself stuck in your own trap... try something
that involves a rocket instead!  It's what Wile E. Coyote would do! ;)

Actually I think sometimes if you're in a hurry there's not time to work out
the bugs even when you know the better way exists...

here is what i have used before:

texture {
  pigment {
    image_map {
      jpeg concat(str(frame_number,-8,0),".jpg")  // ("00000001.jpg", etc)
      map_type 0
      interpolate 2
      once
    }
    translate <-0.5,-0.5,0>   // center background
  }
}

Also, there is no need to use XL. pov-ray is very good at generating
textfiles!
have a look at my rename.pov, it generates a windows/linux rename
batchfile/script (and a black image as a bonus :-)

http://news.povray.org/povray.binaries.utilities/thread/%3Cweb.4240b2b0f6941213a8399d8d0%40news.povray.org%3E/

so you could use pov-ray to generate a pov-ray include file with the big
switch statement...
