 ==2D Glyph==

 Create a 2D glyph (e.g., arrow, cross, dash, etc.).
 
  
 The 2D Glyph source is used for generating a family of 2D glyphs, each of which lies in the xy plane. The output of the 2D Glyph source is polygonal data.<br>

 ==Arrow==
 
  
  
 3D arrow with a long cylindrical shaft and a cone for the tip.
 
  
 The Arrow source appends a cylinder to a cone to form a 3D arrow. The length of the whole arrow is 1.0 unit. The output of the Arrow source is polygonal data. This polygonal data will not contain normals, so rendering of the arrow will be performed using flat shading. The appearance of the arrow can be improved without significantly increasing the resolution of the tip and shaft by generating normals. (Use Normals Generation filter).<br>

 ==Data Object Generator==
 
  
  
 Parses a string to produce composite data objects consisting of simple templated datasets.
 
  
 vtkDataObjectGenerator parses a string and produces dataobjects from the dataobject template names it sees in the string. For example, if the string contains "ID1" the generator will create a vtkImageData. "UF1", "RG1", "SG1", "PD1", and "UG1" will produce vtkUniformGrid, vtkRectilinearGrid, vtkStructuredGrid, vtkPolyData and vtkUnstructuredGrid respectively. "PD2" will produce an alternate vtkPolydata. You can compose composite datasets from the atomic ones listed above  "MB{}" or "HB[]". "MB{ ID1 PD1 MB{} }" for example will create a vtkMultiBlockDataSet consisting of three blocks: image data, poly data, multiblock (empty). Hierarchical Box data sets additionally require the notion of groups, declared within "()" braces, to specify AMR depth. "HB[ (UF1)(UF1)(UF1) ]" will create a vtkHierarchicalBoxDataSet representing an octree that is three levels deep, in which the firstmost cell in each level is refined.<br>

 ==Mandelbrot==
 
  
  
 Representation (unsigned char) of the Mandlebrot set in up to 3 dimensions.
 
  
 The Mandelbrot source can be used to add a uniform rectilinear grid with scalar values derived from the Mandelbrot set to the 3D scene. The equation used is z = z^2 + C (where z and C are complex, and C is a constant). The scalar values in the grid are the number of iterations of the equation it takes for the magnitude of the value to become greater than 2. In the equation, the initial value of z is 0. By default, the real component of C is mapped onto the X axis; the imaginary component of C is mapped onto the Y axis; and the imaginary component of the initial value is mapped onto the Z axis. If a twodimensional extent is specified, the resulting image will be displayed. If a threedimensional extent is used, then the bounding box of the volume will be displayed. The output of the Mandelbrot source is image (uniform rectilinear) data.<br>

 Create a parallelogram given an origin and two points. The resolution indicates the number of division along each axis of the plane.
 
  
 The Plane source can be used to add a polygonal parallelogram to the 3D scene. Unlike the sphere, cone, and cylinder sources, the parallelogram is exactly represented at the lowest resolution, but higher resolutions may be desired if this plane is to be used as an input to a filter. The output of the Plane source is polygonal data.<br>
