[vtkusers] Infovis: Why dense array for vtkAdjacencyMatrixToEdgeTable?

[Eric E. Monson]

Hey,

I was wondering if one of the Titan folks could tell me why  
vtkAdjacencyMatrixToEdgeTable requires a dense array for the adjacency  
matrix? It seems like in many cases that could chew up quite a bit of  
memory with zeros. Also, the table that comes out basically looks like  
a representation of a sparse matrix.

Maybe I'm just thinking too narrowly about my applications where the  
adjacency matrices are often quite sparse...

Thanks,
-Eric
