abstract class to specify dataset behavior
vtkDataSet is an abstract class that specifies an interface for dataset objects. vtkDataSet also provides methods to provide information 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.

int vtkDataSet::GetCellNumberOfFaces | ( | vtkIdType | cellId, |
unsigned char & | cellType, | ||
vtkGenericCell * | cell | ||
) |
Get the number of faces of a cell.
Most of the times extracting the number of faces requires only extracting the cell type. However, for some cell types, the number of faces is not constant. For example, a vtkPolyhedron cell can have a different number of faces for each cell. That's why this method requires the cell id and the dataset.

Locate cell based on global coordinate x and tolerance squared.
If cell and cellId is non-nullptr, then search starts from this cell and looks at immediate neighbors. Returns cellId >= 0 if inside, < 0 otherwise. The parametric coordinates are provided in pcoords[3]. The interpolation weights are returned in weights[]. (The number of weights is equal to the number of points in the found cell).
