The Plane source can be used
to add a polygonal parallelogram to the 3D scene. The origin and two other
corner points that define the parallelogram, as well as the resolution
of the approximation can be specified using the property sheet. As opposed
to the sphere, cone, or cylinder sources, the parallelogram is exactly
represented at the lowest resolution. Higher resolutions may be desired
if this plane is to be used as input for a filter. The plane can be translated,
rotated, and scaled using the Actor control area of the Display tab for
this source, and it can be interactively positioned using the Move operation
of the camera. The
object created by this source is a vtkPlaneSource
object, and the output of this source is vtkPolyData.
. An example of a plane source is given on the right. In
this example, the resolution was set to 10 in X and 10 in Y leading to
the 100 subdivisions that you see in the example image.
The Plane source has the following parameters:
Origin:
The is the location of one of the corners of the parallelogram.
First
Point:This coordinate represents the location of a second corner
of the parallelogram. One edge of the parallelogram will be the line connecting
the origin with this first point, and this will be considered the X axis
of the parallelogram.
Second
Point:This coordinate represents the location of a third corner
of the parallelogram. One edge of the parallelogram will be the line connecting
the origin with this second point, and this will be considered the Y axis
of the parallelogram.
X
Resolution: This is the number of divisions along the X axis of
the parallelogram. By default this value is 1.
Y
Resolution: This is the number of divisions along the Y axis of
the parallelogram. By default this value is 1.
Capping:
This check box indicates whether the cylinder is capped (there are two
N sided polygons closing off the cylinder where N is the resolution) or
open. By default the cylinder will be capped.
