[vtkusers] A general advice for design stage of a new project

[chasank]

Hi,

This question is a bit abstract (actually completely), so please bear with
us. We have been using VTK/ITK for 3 months. We will begin to implement a
big medical project, and now we are at the design stage (writing use cases,
designing UML diagrams, etc). However, because of lack of experience in
VTK/ITK project, we cannot foresee what classes we will need to use in our
project. Which precautions do we need to take so that we will not have to
change initial design dramatically?

For example, in one of our former projects we coded a small medical
application which allows users to display dicom/nifti image data for
3-planes (sagittal, coronal, axial) and to select a dynamic roi with seed
region grow filter. But after that, we needed to add oblique slicing feature
to this project and we had to code from scratch. We do not want to have this
struggle in the future again. Do you have any advice for us based on your
precious experiences?
