[openvrml-develop] VrmlNodeVisitor

[<luc...@li...>]

I managed to write a very basic geometry parser implementing my own 
VrmlNodeVisitor class (for the moment it gets only Boxes' geometry).
Sorry but now i have some more questions... :PP

Why every VrmlNode has a flag to signal if the node has been visited or 
not?
Also i think that even if the addition of a getchildren method in the 
vrmlnode interface would help a lot i believe that traversing the scene 
graph is anyway a process that still depends on node types.
I think that a possible solution to consider would be also to redesign 
the VrmlNodeVisitor class using just a pure virtual destructor and 
implementing all the other virtual functions so that they traverse the 
scene graph without doing anything else. Doing this way one can use the 
base class functions to traverse the scene graph while ovverriding only 
virtual functions that corresponds to nodes of interest.

I managed also to have doxygen generating documentation for the 
complete class hierarchy together with inheritance diagrams and source 
code references. If someone needs the script i used just drop me a line.
