Sorry if the drawing isn't clear (do the images pass the mails submitted in
the mailing list ? If so, I could quickly make a quick drawing, more clearer
that this "verbatim" presentation...) yes E is child of A in my diagram, so
the answer is B-A-E0-D-C-E1.
I understand that in fact you're saying than the binNumber is the draw order
number against other children in the parent Group, evaluated in a left-first
traversall logic. However binNumber inside drawable list of Geode are
evaluated at once (otherwise the answer would have be B-A-E0-E1-D-C).
If can submit small pictures I may ask a last case where B as children.
I'm sorry I missed something in my second diagram (there is no multipass in
the one I submitted). In fact I'm wondering about that situation
(encountered in a personnal shadowMap implementation) :
|
osg::Group "Root"
|
-------------------------------------
| | |
| | |
| osg::Group "B" osg::Group "C"
| [binNumber = 20] [binNumber = 30]
| | |
----------------------------------
|
osg::Geode "A"
[binNumber = 15]
A is child of "Root", B and C simultaneously (therefore A is rendered three
times, with stateset context successivley of Root, B, and C).
Is the draw order A-B-C ?
Thanks for those explanations,
