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

==Arrow==

 +
3D arrow with a long cylindrical shaft and a cone for the tipThe 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).

==Data Object Generator==
 +

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)

The Wavelet source can be used to create a uniform rectilinear grid in up to three dimensions with values varying according to the following periodic function. OS = M * G * (XM * sin(XF * x) + YM * sin(YF * y) + ZM * cos(ZF

  • z)) OS is the output scalar; M represents the maximum

value; G represents the Gaussian; XM, YM, and ZM are the X, Y, and Z magnitude values; and XF, YF, and ZF are the X, Y, and Z frequency values. 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.

Property Description Default Value(s) Restrictions
Whole Extent (WholeExtent)

The six values in this property indicate the X, Y, and Z extent of the output data. The first two values represent the minimum and maximum X indices, the next two are the minimum and maximum Y indices, and the last two are the minimum and maximum Z indices.

Center (Center)

This property specifies the 3D coordinates of the center of the dataset.

0.0 0.0 0.0

Maximum (Maximum)

This parameter specifies the maximum value (M) of the function.

255.0

XFreq (XFreq)

This property specifies the natural frequency in X (XF in the equation).

60.0

YFreq (YFreq)

This property specifies the natural frequency in Y (YF in the equation).

30.0

ZFreq (ZFreq)

This property specifies the natural frequency in Z (ZF in the equation).

40.0

XMag (XMag)

This property specifies the wave amplitude in X (XM in the equation).

10.0

YMag (YMag)

This property specifies the wave amplitude in Y (YM in the equation).

18.0

ZMag (ZMag)

This property specifies the wave amplitude in Z (ZM in the equation).

5.0

StandardDeviation (StandardDeviation)

This property specifies the standard deviation of the Gaussian used in computing this function.

0.5

SubsampleRate (SubsampleRate)

This property specifies the rate at which to subsample the volume. The extent of the dataset in each dimension will be divided by this value. (See the Whole Extent property.)
