What is the best way to store data for a model, loaded from DICOM-RT ion plan file?

Currently i’m working on loading and visualization of ion range compensator,
which data is loaded from DICOM-RT ion plan file. The compensator volume data taken from the dicom file are very similar to image parameters: rows, columns, pixel spacing, thickness data.

The compensator is going to be a square block or slab with a milled down center part of the block by a milling machine.

Typical amount of data isn’t very large, for rows=50 and columns=50, thickness data size is 2500 single precision digits.

What is best way to store the data for model visualization?

  1. A class derived from vtkMRMLModelNode, and thickness data is stored as std::vector< float >.
  2. A class derived from vtkMRMLModelNode, and thickness data is stored as observed vtkMRMLTableNode.
  3. A loader member function which takes the data and creates a compensator model.
