hi,

a simple, short animation of a sphere (~25M, ~29secs), plays full-screen.

Interesting idea to show object from 4 points simultaneously, how did
you combined the views ? Also reminds me a paintings of Kazimir
Malevich ).

"magick" </grin>.  literally, the name of the command installed (on Slackware)
as part of the ImageMagick tools.  it allows one to place images (in layers) on
a "canvas" and "flatten" those in an output image.  will send an example later.

thank you. (Google and Wikipedia show many interesting paintings)

red
metallic cube & sphere

Nice twist :)

Presumably you had a system for filenames for each of the panes?

I would imagine one could create a 5th animation scene to use the image maps
from the first 4, but imagemagick was probably 1000 times faster.

thanks.  (yes, all "that pain" for one little thing :-))

yes, o/wise it'd be real work </grin>.  I have a single scene file (plus .inc)
and four ini files, one "run_" per camera;  frame/file names were
'*_[1234]_*.png'. also two "one-liner" shell scripts, to assemble the frames and
to convert to mp4.

that would have been "the fallback", had I not "lucked out" with the ImageMagick
tools.

It just occurred to me that we can probably use the user-defined mesh camera to
do it all in the first pass.

that is an interesting idea.  I can tidy-up and post the code if you're minded
to pursue it.

Scratch that,
using the _mesh projection_ would be a giant pain my sphere {}s.

HOWEVER,
using the user-defined function camera
("User defined projection")
would probably allow one to map out the portions of the screen as an
image/diagram
and then use eval_pigment in a function to control the location and direction of
the camera at each pixel.

I think I can just use something like a cubic pattern and different colored
faces to get everything working.
Then it would just be a plug-n-play kind of setup, if I wrote the scene code for
a fairly general case.
