Detailed Description

create a random cloud of points.

Date:

2001/10/11 13:37:11

Revision:

1.39

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.

Examples:

Tests:

Member Function Documentation

vtkPointSource* vtkPointSource::New (    )  [static]

Instantiate object with no start, end, or progress methods. Reimplemented from vtkPolyDataSource.

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

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataSource.

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 vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataSource.

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 vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataSource.

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

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataSource.

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 vtkSource.

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

Set the number of points to generate.

virtual vtkIdType vtkPointSource::GetNumberOfPoints (    )  [virtual]

Set the number of points to generate.

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

Set the center of the point cloud.

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

Set the center of the point cloud.

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

Set the center of the point cloud.

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

Set the center of the point cloud.

virtual void vtkPointSource::SetRadius (  float    )  [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 float 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 and empty sphere.

void vtkPointSource::SetDistributionToUniform (    )  [inline]

Specify the distribution to use. The default is a uniform distribution. The Shell distribution produces and empty sphere. Definition at line 96 of file vtkPointSource.h.

void vtkPointSource::SetDistributionToShell (    )  [inline]

Specify the distribution to use. The default is a uniform distribution. The Shell distribution produces and empty sphere. Definition at line 98 of file vtkPointSource.h.

virtual int vtkPointSource::GetDistribution (    )  [virtual]

Specify the distribution to use. The default is a uniform distribution. The Shell distribution produces and empty sphere.

void vtkPointSource::Execute (    )  [protected, virtual]

This method is the old style execute method Reimplemented from vtkSource.

void vtkPointSource::ExecuteInformation (    )  [protected, virtual]

Reimplemented from vtkSource.
