Hi Sascha,
thanks for looking into this!
Your idea sounds good. The internal order in the data storage does not
matter, just the order in the data manager, i.e. the layer.
Suddenly this issue become top priority for us for the command line
integration of NifTK with another in-house software.
There will probably be other requirements, e.g. specifying the parent-child
relation of nodes in the command line, or specifying arbitrary properties.
We are still gathering the exact requirements, it can happen that we will
need to write a helper app that creates a full project scene file that can
then be loaded at start.
Either way we go, it would be good to agree in a command line syntax for
specifying node properties and hierarchy from the command line. It's going
to be complicated because we will surely need to specify renderer specific
properties as well. (It comes very handy that they are now assigned to the
renderer names, not the address. We know the renderer names at start.)
What do you think?
Thanks,
Miklos
