vtkDataSet

是一个表示数据集对象的抽象类，算法流处理对象都是数据集，下面是官方介绍

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.

vtkDataSet由结构数据(geometry&topology) 和属性数据（attribute data）组成。

结构数据由一个cells集合显示或者隐式的定义。这里geometry 表示的是点的序号信息，topology由cell的类型表示这些点该怎么表达（点，线，面，多边形？）
