[vtkusers] Adding a vtkAssembly onto another vtkAssembly? Is this possible?

Dear David,

Thanks for your response.

Yes, turns out you can add one vtkAssembly to another.

Now, the question really is how can one store multiple copies/instances of
vtkAssembly's?

If the number of possible vtkAssembly's were known, I would have opted for
a fixed size array, however I can only think of the C++ Vector.

This is what I can think of as a data structure...
*vector<vtkAssembly> actorCombo*

Are there better data structures for handling multiple vtkAssembly's?

Also, I am having some difficulty storing multiple glyph's that are plotted
on a vtkActor. Basically, I can store vtkActor's as  *vector<vtkActor>
actors*
but I don't know how to store and associate the multiple glyph's to each
actor. If I were to use C Style arrays, I could opt for a 2D array, such
that [i][j], where [i] would represent the index of the actor and [j] would
represent each glyph object. How would I go about storing it as a vector?

Also, in terms of memory management, what is better - linked lists or
vectors?

Would greatly appreciate it if you or anyone on this forum could answer my
questions. It would really mean a lot to me.

Many Thanks
