* @class vtkGraphToGlyphs
|
|
* @brief create glyphs for graph vertices
|
|
*
|
|
*
|
|
* Converts a vtkGraph to a vtkPolyData containing a glyph for each vertex.
|
|
* This assumes that the points
|
|
* of the graph have already been filled (perhaps by vtkGraphLayout).
|
|
* The glyphs will automatically be scaled to be the same size in screen
|
|
* coordinates. To do this the filter requires a pointer to the renderer
|
|
* into which the glyphs will be rendered.
