I have found out that when 'orthographic camera' is selected, one has
to play with the
values of 'angle' and the 'zoom' to frame the whole picture into the
window as desired.
Therefore, I think it does not make sense to complicate the dialog box
any further and
leave it as it is. So, I had to learn another software in my busy life
(meaning old age),
but it's OK. Thanks again.

I have two observations which I'd like to mention about the Jmol and
POV-Ray relationship.
After some scripting etc I obtain my crystal structure on the Jmol
window and set perspectiveDepth off.
Then I open the dialog box for POV-Ray Rendering, checkmark 'Image
size', Width=1024, Fixed Ratio=4:3
and I see in the Height window a flu 768, which is fine, but when I
punch 'Go!' nothing happens.
[1st Q: Is this a bug and can it be fixed easily??]
We need to know more about your system configuration.
Windows XP
I have only launched PovRay on Linux, but I think that others have used it
on Windows.
If I choose Width=768, [4:3, and 576] it works and I get a bmp or ppm
picture, but it is taken with
a 'perspective' camera (which is the default for POV-Ray).
[2nd Q: Can 'set perspectiveDepth off' command be made transferrable?]
Good suggestion.
If I open pov file in POV-Ray, (apart from resetting the width and
height) I can change the default and
put 'orthographic' as the first parameter in the statement
camera{orthographic
location < 0, 0, zoom>
right < -Ratio , 0, 0>
look_at < 0, 0, 0 >
}
but this time I get a picture of a full-page sphere (a single atom
instead of hundreds of them).
I do not know povray commands very well ... and it has been a long time
since I worked on that code.
Perhaps someone else knows PovRay well enough to tell the developers how
to do this.
[3rd Q: If Q2 is not possible to be solved, is there anybody in this
list who is familiar with POV-Ray and
can tell me what to do to obtain a nonperspective picure?]
If someone can tell you how to do it then this could easily be added to
the PovRay support in the Jmol application.
