I am new QSG user. I am trying to load the model from externally created

method. Unfortunately that did not work. I am getting invalid osg::Node.
Ok. You don't really say WHY you're trying to do it this way -- often what
you regard as
a problem is just not doing it the intended way. Maybe if you told us the
goal, we could
suggest an easy way to get there that doesn't even involve the technique (and
problem)
you're currently faced with.
Maybe anybody knows if it is the right direction or I should look for another
way to load model from byte array.
I don't think ReadNode can read from a byte array. I think it wants something
that looks
like a filestream. If you're familiar with C++, I think you could use the
stringstream
classes to create somethign that looks and behaves like a file/stream from your
byte
array, and possibly pass that to ReadNode. I'd have to go look at the readnode
prototypes
to see if this is possible.
Any help is very appreciated.
Thank you!
Cheers,
Oleg
