Revision:: 1.79

vtkUnstructuredGrid is a data object that is a concrete implementation of vtkDataSet. vtkUnstructuredGrid represents any combinations of any cell types. This includes 0D (e.g., points), 1D (e.g., lines, polylines), 2D (e.g., triangles, polygons), and 3D (e.g., hexahedron, tetrahedron).
