Class PointSource

Known Subclasses:

streamline.StreamLine

Class that defines the source (location) to generate points. The points are generated within the radius of a sphere.

Instance Methods

__init__(self)
Initialise the point source.

vtkPolyData

_getPointSourceOutput(self)
Return the output of the point source.

Boolean

_isPointSourceCenterSet(self)
Return whether the center has been specified.

_setPointSourceCenter(self)
Set the sphere's center.

_setupPointSource(self, object)
Setup the point source.

setPointSourceCenter(self, center)
Specity the sphere's center.

setPointSourceNumberOfPoints(self, points)
Set the number of points to generate within the sphere (the larger the number of points, the more streamlines are generated)

setPointSourceRadius(self, radius)
Set the radius of the sphere.
