Detailed Description

abstract class to specify dataset behavior

vtkDataSet is an abstract class that specifies an interface for dataset objects. vtkDataSet also provides methods to provide informations about the data, such as center, bounding box, and representative length.

In vtk a dataset consists of a structure (geometry and topology) and attribute data. The structure is defined implicitly or explicitly as a collection of cells. The geometry of the structure is contained in point coordinates plus the cell interpolation functions. The topology of the dataset structure is defined by cell types and how the cells share their defining points.

Attribute data in vtk is either point data (data at points) or cell data (data at cells). Typically filters operate on point data, but some may operate on cell data, both cell and point data, either one, or none.
