Daniel,
Hi, I am so sorry that I am not quite sure what ASCII NMG is.
The current status of the nmgreorg:All model and nmgregion have been
removed.The new-nmg can facetize single primitive (e.g. rcc, sph) as
expected.To support facetizing multiple-primitive, i.e. the combination, I am
trying to write a new version of import5 and export5 according to the similar
parts in comb.c and nmg.c. Because it should traversal not only the
BRL-combination tree, but also the shell structure.
With more and more familiar with nmg-related codes, I have more confidence in
replacing model and nmgregion with BRL-conbination. But the only concern is
whether the new-nmg can describe hollow model well , which can be represented
by a nmgregion with an inner shell and a outer shell in old-nmg methodology.
And more important, Thanks for you and any other mentor's help, suggestion,
discussion, training, and criticism. I learn much here. I will keeping trying
my best to finish this project.
B.R.

Zhao,
I just tested facetize with a simple region (see the attached file).
Then I wanted to see how many shells it has produced. I thought
looking at the ASCII version of the database would be a good idea
(created with g2asc). However, the ASCII NMG has always only one
shell: rt_nmg_adjust() modifies only the first shell.
Therefore I'm more and more convinced that we don't need the
model-nmgregion structures. Even the work-around with the
combinations may be unnecessary (but I'm not sure).
At least the ASCII import and export should be no problem with the
single-shell nmg. I'ts ASCII format knows only one shell.
Regards,
Daniel
