[vtk-developers] Composite Data Redesign

[Utkarsh Ayachit]

Folks,

Composite data pipeline is undergoing a redesign to overcome some of its 
current limitations.  Details of the issues, the new design and the 
implementation are available at:

http://www.vtk.org/Wiki/VTK/Composite_Data_Redesign

To summarize: vtkCompositeDataSet has been modified to support a full 
tree datastructure instead of a table of tables approach used by the 
previous implementation. It is possible to traverse the tree using 
iterators. The iterators are more powerful than before making it 
possible to not only access the datasets, but also change them. 
vtkHierarchicalDataSet and vtkMultiGroupDataSet have been deprecated. 
The only concrete composite datasets available are vtkMultiBlockDataSet, 
vtkHierarchicalBoxDataSet and vtkTemporalDataSet.

The new code is not available in CVS yet. I'll wait a few days for 
people to respond before committing it.
