So what do I *do* If I haven't got PNG? or TGA?
  I've got Photo deluxe 2.0,(Hahaha!!) and PS 5 (LE, nice!). Deluxe can
convert an image to .jpeg, but it won't do it, with Pov.
   I am at a loss, so far!

What do you mean?
Are you trying to convert a .pov file? That won't work, you have to 
render it with POV and convert the resulting image. POV-Ray can output 
to many file formats, including TGA and PNG. The default settings place 
the rendered image in the same folder the .pov file is in.

My guess is that (s)he is saying that nothing there is capable of opening a
Targa or Portable Network Graphics image.  But only because I'm not sure
about what either of those programs can open.  Somehow I'd bet Photoshop
could do it, just a hunch.

I think the equations  would just be

u(xx) + u(yy) + u(zz) = 0 and

u(x+1,y,z) + u(x,y+1,z) + u(x-1,y,z) + u(x,y-1,z) + u(x,y,z+1) + u(x,y,z-1) =
6*u(x,y,z)

I could convert my code quite easy to 3D for testing purposes but it would
require lots of RAM to run. Then I would write a macro that outputs an object/volume
as voxel image slice by slice as animation. What's the format of the pov
voxel image type (for input to pov)?

This setup would be enough to determine how useful Volume Connector :) vould be.

The density_file.

from the doc: "The df3 format consists of a 6 byte header of three 16-bit 
integers with high order byte first. These three values give the x,y,z 
size of the data in pixels (or more appropriately called voxels). This is 
followed by x*y*z unsigned integer bytes of data. The data in the range of 
0 to 255 is scaled into a float value in the range 0.0 to 1.0. It remains 
at 0.0 for all areas beyond the unit cube. The pattern occupies the unit 
cube regardless of the dimensions in voxels."

Yes. If the volume contains just the object with potential 1 and the
remaining space is set free then every iteration pass would diffuse
the objects "electrical field" very smoothly around the object.

Hi Chris, apologies, that was the beer talking last night ;o)

   In Pov, I can't see any clear option to turn an image into a JPEG image,
like you can in Photo Deluxe 2 or Photoshop 5.   However, I have now found
my image saved as a .bmp, in MS Paint??!! (how'd it get there?)
   After rendering, do the images save as .bmp's by default? And is it ok to
send to pov.images in this format?
    As i've said in .newusers, i'm 'puter illit. So finding my way around
mine is a nightmare sometimes. I've only had it 6 months :o(  but i'm
getting there :o)

In the winpov, yes.

jpg is the best format because you can choose between file size
and image quality. In photoshop open bmp, file/save a copy, choose jpg,
check preview, move the slider left until the image starts to look bad,
now save an post :)

  Hi, Steve. I suggest reading all of the messages in the
povray.announce.frequently-asked-questions group, specifically "Where
can I post my binary or text file?"
