// .NAME vtkPointSource - create a random cloud of points

|
|
// .SECTION Description
|
||
|
|
// vtkPointSource is a source object that creates a user-specified number
|
||
|
|
// of points within a specified radius about a specified center point.
|
||
|
|
// By default location of the points is random within the sphere. It is
|
||
|
|
// also possible to generate random points only on the surface of the
|
||
|
|
// sphere.
