XMLDAE : raw G4DAE node structure
=====================================
.. contents:: :local:
Questions
----------
#. Would the xml documument ids be unique without the pointers 0x.... ?
* checking the .gdml there are dupes in the subtraction/union solids and between element/material names
see ~/e/tools/checkxml.py
* checking the GDML writing on which the DAE writing is based, there is currently only a global addPointerToName
switch so cannot easily turn it off for volumes and not for solids as would break references to solids
#. Can I reproduce VRML2 output from the DAE ? As a validation of all those transformations and everything else.
* PV count now matches
* PV name matching, the NCName IDref XML restriction forced replacing 3 chars ":/#" with "_"
* that is difficult to reverse, need some more unused acceptable chars (single chars would be best)
* iterating on dae-edit;dae-validate find that "." and "-" are acceptable on other than the first char
* http://www.schemacentral.com/sc/xsd/t-xsd_NCName.html

* TODO:
* add checkxml.py collection of all id characters to see if "." is used

Raw Node Tree
--------------
Raw Node tree has the lv as well as pv, wherese VRML2 tree has only pv ?
* the raw collada node tree triples the Geant4 volume tree nodes into a regular PPV/LV/GEO per volume structure

Looks to be a pattern that the LV referenced by instance_node are skipped in the VRML2 list.
* yes, the VRML2 has just the PV

Compare daenames with wrlnames : tracing the id
----------------------------------------------------
Succeed to match the bases, but not the `.1001` extensions::
echo "select rtrim(substr(name,0,instr(name,'.'))) from shape ;" | sqlite3 -noheader $(shapedb-path) > wrlnames.txt
cat wrlnames.txt | cut -d" " -f1 > wrlnames.cut.txt # get rid of bizarre whitespace padding
diff wrlnames.cut.txt daenames.txt # they match
The WRL names, are actually coming from `G4PhysicalVolumeModel::GetCurrentTag`
