Detailed Description

dataset represents arbitrary combinations of all possible cell types

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, polyhedron, etc.).

Method allocates initial storage for the cell connectivity. Use this method before the method InsertNextCell(). The array capacity is doubled when the inserting a cell exceeds the current capacity. extSize is no longer used.

vtkIdType vtkUnstructuredGrid::InsertNextCell	(	int	type,

For polyhedron cell, a special input format is required. npts is the number of faces in the cell. ptIds is the list of face stream: (numFace0Pts, id1, id2, id3, numFace1Pts,id1, id2, id3, ...)
