VTK Data Structures (for vtkUnstructuredGrid and in general)
Some official resources about data representation in VTK
- Data structures discussion in VTK Book (Chapter 5)
- Mesh types (Dataset types) in VTK Book
- Tuples in VTK Book
- Data arrays in VTK Book
- Wiki Tutorial about data arrays (pretty advanced stuff)
Specific classes
Why vtkUnstructuredGrid?
In the project, which I am going to develop I I am going to use almost exclusively unstructured grids (at least for now). So I am mostly interested about this dataset type. But I guess, that some basic part (e.g. related to data arrays) is relevant to all dataset types (mesh types). But even pieces, which are specific to unstructured grids may have some ideas, which are still relevant for other types of datasets.
Data structures - bottom up approach
Tuples (within Data Arrays)
In the description of API or names of the methods of different data structures in VTK
one may often see the word "tuple" even though there is no correspnding type present
(don't confuse with vtkTuple).
E.g. method vtkDataArray::InsertTupple().
