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 x-y plane. The output of the 2D Glyph source is
polygonal data.

==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, multi-block (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.

==Mandelbrot==
 
Representation (unsigned char) of the Mandlebrot set in up to 3 dimensionsThe
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 two-dimensional extent is
specified, the resulting image will be displayed. If a
three-dimensional extent is used, then the bounding box of
the volume will be displayed. The output of the Mandelbrot
source is image (uniform rectilinear)
data.
