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.

Examples:

Tests:

Member Function Documentation

static vtkPointSource* vtkPointSource::New (   )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on. Reimplemented from vtkPolyDataAlgorithm.

virtual const char* vtkPointSource::GetClassName (   )  [virtual]

Reimplemented from vtkPolyDataAlgorithm.

static int vtkPointSource::IsTypeOf (  const char *  type  )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataAlgorithm.

virtual int vtkPointSource::IsA (  const char *  type  )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataAlgorithm.

static vtkPointSource* vtkPointSource::SafeDownCast (  vtkObject *  o  )  [static]

Reimplemented from vtkPolyDataAlgorithm.

void vtkPointSource::PrintSelf (  ostream &  os, vtkIndent  indent )  [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkPolyDataAlgorithm.

virtual void vtkPointSource::SetNumberOfPoints (  vtkIdType   )  [virtual]

Set the number of points to generate.

virtual vtkIdType vtkPointSource::GetNumberOfPoints (   )  [virtual]

virtual void vtkPointSource::SetCenter (  double  , double  , double  )  [virtual]

Set the center of the point cloud.

virtual void vtkPointSource::SetCenter (  double  [3]  )  [virtual]

Set the center of the point cloud.

virtual double* vtkPointSource::GetCenter (   )  [virtual]

Set the center of the point cloud.

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. Definition at line 71 of file vtkPointSource.h. References VTK_POINT_UNIFORM.

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. Definition at line 73 of file vtkPointSource.h. References VTK_POINT_SHELL.

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.

int vtkPointSource::RequestData (  vtkInformation *  , vtkInformationVector **  , vtkInformationVector *  )  [protected, virtual]

This is called by the superclass. This is the method you should override. Reimplemented from vtkPolyDataAlgorithm.
