/**

|
* @class vtkGlyphSource2D
|
|
* @brief create 2D glyphs represented by vtkPolyData
|
|
*
|
|
* vtkGlyphSource2D can generate a family of 2D glyphs each of which lies
|
|
* in the x-y plane (i.e., the z-coordinate is zero). The class is a helper
|
|
* class to be used with vtkGlyph2D and vtkXYPlotActor.
|
|
*
|
|
* To use this class, specify the glyph type to use and its
|
|
* attributes. Attributes include its position (i.e., center point), scale,
|
|
* color, and whether the symbol is filled or not (a polygon or closed line
|
|
* sequence). You can also put a short line through the glyph running from -x
|
|
* to +x (the glyph looks like it's on a line), or a cross.
