Detailed Description

create a random cloud of points

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. The output PolyData has the specified number of points and 1 cell - a vtkPolyVertex containing all of the points.

virtual void vtkPointSource::GetCenter ( double  data[3])
virtual

Set the center of the point cloud.

virtual void vtkPointSource::SetRadius ( double  )
virtual

Set the radius of the point cloud. If you are generating a Gaussian distribution, then this is the standard deviation for each of x, y, and z.

virtual double vtkPointSource::GetRadius ( )
virtual

Set the radius of the point cloud. If you are generating a Gaussian distribution, then this is the standard deviation for each of x, y, and z.

virtual void vtkPointSource::SetDistribution ( int  )
virtual

Specify the distribution to use. The default is a uniform distribution. The shell distribution produces random points on the surface of the sphere, none in the interior.

void vtkPointSource::SetDistributionToUniform ( )
inline

Specify the distribution to use. The default is a uniform distribution. The shell distribution produces random points on the surface of the sphere, none in the interior.

void vtkPointSource::SetDistributionToShell ( )
inline

Specify the distribution to use. The default is a uniform distribution. The shell distribution produces random points on the surface of the sphere, none in the interior.

virtual int vtkPointSource::GetDistribution ( )
virtual

Specify the distribution to use. The default is a uniform distribution. The shell distribution produces random points on the surface of the sphere, none in the interior.
