Thanks, with pleasure. Also few more or less ready examples available here under
'Examples' tab:
https://www.mathworks.com/matlabcentral/fileexchange/123520-pov-lab-matlab-interface-to-pov-ray
Any ideas and suggestions always welcome !

thanks for the screenshot ('todo', 'notes', I felt right at home :-)) and the
link. looks all pretty polished, already ;-). intrigued by the volume view, is
that a slice from 'mri.df3'?
regards, jr.

Always welcome, please be my guest :). It works stable now, but still too far
from perfect condition - I am only starting ...
As to volume, you are right, I am using this techniques:

Please find the scene in attachment.

have not yet looked at/run the scene code, but did (quickly) look over the pdf
you mentioned. the latter parts made me realise that there's a new todo list to
be made.. :-) (although a frown would have fitted too ;-))

I understand you - this PDF inspires me to start my package, as volume
visualization always attracts me a lot. It was the first method I've done.

found a few minutes to look at the files. nice + v tidy already, but you knew
that :-). re 'volume.pov', just nit-picking, a bit more "vertical whitespace",
empty lines between statements would be nice. re the .inc file, it shouldn't
really have a 'global_settings' block (fact, POV-Ray complains when it finds the
second, in the scene file); curiously, the file has Microsoft style line endings
whereas the scene does not. there's a "standard" way of making .inc files
idempotent like C type headers, suggest adding the "usual" '#ifndef' guard and
the (local) '#version', and the filename for display via the
'View_POV_Include_stack'. final "nits": I think the ';' terminator should
always be written, for every '#local' and '#declare', but realise I'm probably
in a minority of one :-), and prefer code line lengths .. conservative, ideally
less than 96 chars/line, but, again, that is just a personal view.
also, have decided to "steal" your 'color_map' for a couple of things I want to
try out soon. cheers.
regards, jr.

Hi,
Many thanks for finding a time for code-review - it's very important to me, as I
am newbie to POV-world. Volume was the first scene I've made, so it full of
clumsiness. I will apply all of your remarks in next refactoring.
As to color map - it's not mine, I've also staled it from Matlab, and if you
will like any other, I can do it for you again in a one click.
Please find all Matlab's standard color maps here (near the bottom):
https://www.mathworks.com/help/matlab/ref/colormap.html
Happy voluming and colormapping.

Hi, jr
I've attached the most tasty maps to this message, btw, don't you know how to
scale them properly, I mean map to object whole specter completely ?
Reading manual:
https://www.povray.org/documentation/view/3.6.1/335/
and a lot of experiments with scaling gives no result.

Apply the pigment to the unit sphere and /then/ scale the sphere:
sphere {
<0,0,0>, 1
pigment {
gradient y
color_map {spring}
}
scale 10
}
