Hello all,

I have [recently discovered][link] that `no_image` has no effect in a nested
difference > union > member CSG.

I have perused the existing documentation before asking on the povray.general
newsgroup, but I haven't found sufficiently detailed information about the
interaction of these attributes with CSG. Are the details documented somewhere
that I have missed? If not, would it be a good idea to document it somewhere? Is
there any way I can help contribute?

Cheers,

Oblomov

The documentation is in Wiki (and that's the master for other
documentations, as far as I known).

http://wiki.povray.org/content/Main_Page

The page of the wiki are usually locked (due to hooligans), but you can
provide contribution in the "discussion" page of the page you want to
change.

Now, to become a registered user on the wiki, I forgot how to do that.

As everyone is lazy (ok, I am very lazy when it comes to documentation),
it is probably better to provide fully updated paragraph(s) in the
discussion page, than providing only questions & comments (but you can
have questions and comments in discussion page, no problem), or
indication such as "the subject should be plural, or you need to
conjugate the verb" (you have the solution; so share it, and do not make
other think and redo your work).

I would believe that object modifiers such as no_image, no_reflection,
no_shadow would apply only at the top level (CSG are probably alone in
having depths in composition), but I really never though about it.
