Detailed Description

Read a Chaco file and create a vtkUnstructuredGrid.

vtkChacoReader is an unstructured grid source object that reads Chaco files. The reader DOES NOT respond to piece requests. Chaco is a graph partitioning package developed at Sandia National Laboratories in the early 1990s. (http://www.cs.sandia.gov/~bahendr/chaco.html)

Note that the Chaco "edges" become VTK "cells", and the Chaco "vertices" become VTK "points".

◆ SetGenerateGlobalNodeIdArray()

virtual void vtkChacoReader::SetGenerateGlobalNodeIdArray ( vtkTypeBool  )
virtual

Indicate whether this reader should create a point array of global IDs for the points in the output vtkUnstructuredGrid.

These points are the vertices that were in the Chaco file. Global point IDs start at "1" for the first vertex in BaseName.coords and go up from there. Default is ON.

◆ SetGenerateVertexWeightArrays()

virtual void vtkChacoReader::SetGenerateVertexWeightArrays ( vtkTypeBool  )
virtual

Indicate whether this reader should create a point array for each vertex weight in the Chaco file.

Default is OFF.

◆ GetNumberOfVertexWeights()

virtual int vtkChacoReader::GetNumberOfVertexWeights ( )
virtual

Returns the number of weights per vertex in the Chaco file, whether or not GenerateVertexWeightArrays is ON.

◆ GetVertexWeightArrayName()

const char* vtkChacoReader::GetVertexWeightArrayName ( int  weight)

This method returns the name of the selected Vertex weight point array.

If you did not turn on GenerateVertexWeightArrays, or if the weight you requested is invalid, it returns nullptr. Weights begin at one and go up to NumberOfVertexWeights. This is a pointer to our copy of the name, so don't "delete" it.

◆ SetGenerateEdgeWeightArrays()

virtual void vtkChacoReader::SetGenerateEdgeWeightArrays ( vtkTypeBool  )
virtual

Each edge in the Chaco file connects two vertices.

The file may specify one or more weights for each edge. (The weight for an edge from vertex A to vertex B equals the weight from B to A.) Indicate with the following parameter whether this reader should create a cell array for each weight for every edge. Default is OFF.

virtual

◆ GetNumberOfEdgeWeights()

virtual int vtkChacoReader::GetNumberOfEdgeWeights ( )
virtual

Returns the number of weights per edge in the Chaco file, whether or not GenerateEdgeWeightArrays is ON.

◆ GetEdgeWeightArrayName()

const char* vtkChacoReader::GetEdgeWeightArrayName ( int  weight)

This method returns the name of the selected Edge weight cell array.

If you did not turn on GenerateEdgeWeightArrays, or if the weight you requested is invalid, it returns nullptr. Weights begin at one and go up to NumberOfEdgeWeights. This is a pointer to our copy of the name, so don't "delete" it.

◆ GetDimensionality()

◆ GetNumberOfCellWeightArrays()

virtual int vtkChacoReader::GetNumberOfCellWeightArrays ( )
virtual

After this filter executes, this method returns the number of cell arrays that were created to hold the edge weights.

It is equal to NumberOfEdgeWeights if GenerateEdgeWeightArrays was ON.

◆ GetNumberOfPointWeightArrays()

virtual int vtkChacoReader::GetNumberOfPointWeightArrays ( )
virtual

After this filter executes, this method returns the number of point arrays that were created to hold the vertex weights.

It is equal to NumberOfVertexWeights if GenerateVertexWeightArrays was ON.
