// .NAME vtkVertexGlyphFilter - Make a vtkPolyData with a vertex on each point.
//
// .SECTION Description
//
// This filter throws away all of the cells in the input and replaces them with
// a vertex on each point.  The intended use of this filter is roughly
// equivalent to the vtkGlyph3D filter, except this filter is specifically for
// data that has many vertices, making the rendered result faster and less
// cluttered than the glyph filter. This filter may take a graph or point set
// as input.
