Glyph Filter in ParaView

The Glyph filter uses the VTK filter vtkPVGlyphFilter. The filter generates an arrow, cone, line, sphere, or 2-D glyph at each point in the active data set. This could result in an excessive number of glyphs and cause poor performance. To remedy this, ParaView allows the user to specify the maximum number of glyphs and to mask some points randomly.

  1. First the user selects the data they wish to operate on from the Selection Window. It will be highlighted when this occurs.
  2. The user can then select Filter->Alphabetical->Glyph from the main menu or click on the Glyph Button Button.
  3. The user can select from the Glyph pulldown menu whether or not they want arrow, cone, line, sphere, or 2-D glyphs.
  4. The orientation and scale of the glyphs can be changed in the Orient/Scale section.
    1. The glyphs can be oriented along the line of the vector data.
    2. The glyphs can be scaled according to:
      1. the scalar variable
      2. the vector magnitude
      3. a component of the vector
      4. turned off.
    3. Also the glyphs can be scaled according to some factor the user decides to input.
  5. ParaView allows the user to specify the maximum number of glyphs in order to improve performance and not clutter the screen.
  6. The Apply button must be pressed before the output will be generated.
