Implicit Arrays

Pain Point

Some specific types of arrays defined on geometries take far more memory then they should. For example, if one wishes to define a value that is everywhere constant over a data set then they have to allocate an arrays that is the size of the data set. This is a waste of precious RAM and can be dealt with in a more efficient manner.

Solution

This development aims to include a new type of vtkGenericDataArray into vtk. These arrays will be implemented in the vtkImplicitArray class and will mimic the interface of classic vtkDataArrays while actually being an implicit function/map in the background.
