vtkMaskPoints is a filter that passes through points and point attributes from input dataset. (Other geometry is not passed through.) It is possible to mask every nth point, and to specify an initial offset to begin masking from. A special random mode feature enables random selection of points. The filter can also generate vertices (topological primitives) as well as points. This is useful because vertices are rendered while points are not.

Member Function Documentation
virtual const char* vtkMaskPoints::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 vtkDataSetToPolyDataFilter. |
virtual int vtkMaskPoints::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 vtkDataSetToPolyDataFilter. |
int vtkMaskPoints::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 vtkDataSetToPolyDataFilter. |
vtkMaskPoints* vtkMaskPoints::New |
( |
|
) |
[static] |
|
|
Instantiate object with no start, end, or progress methods.
Reimplemented from vtkPolyDataSource. |
void vtkMaskPoints::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. |
vtkMaskPoints* vtkMaskPoints::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 vtkDataSetToPolyDataFilter. |
virtual void vtkMaskPoints::SetGenerateVertices |
( |
int |
|
) |
[virtual] |
|
|
Generate output polydata vertices as well as points. A useful convenience method because vertices are drawn (they are topology) while points are not (they are geometry). By default this method is off. |
virtual void vtkMaskPoints::SetMaximumNumberOfPoints |
( |
int |
|
) |
[virtual] |
|
|
Limit the number of points that can be passed through. |
virtual void vtkMaskPoints::SetOffset |
( |
int |
|
) |
[virtual] |
|
virtual void vtkMaskPoints::SetOnRatio |
( |
int |
|
) |
[virtual] |
|
virtual void vtkMaskPoints::SetRandomMode |
( |
int |
|
) |
[virtual] |
|
|
Special flag causes randomization of point selection. If this mode is on, statistically every nth point (i.e., OnRatio) will be displayed. |
