* @brief convert a vtkGraph to vtkPolyData
|

|
*
|
||
|
|
* Converts a vtkGraph to a vtkPolyData. This assumes that the points
|
||
|
|
* of the graph have already been filled (perhaps by vtkGraphLayout),
|
||
|
|
* and coverts all the edge of the graph into lines in the polydata.
|
||
|
|
* The vertex data is passed along to the point data, and the edge data
|
||
|
|
* is passed along to the cell data.
|
||
|
|
*
|
||
|
|
* Only the owned graph edges (i.e. edges with ghost level 0) are copied
|
||
|
|
* into the vtkPolyData.
