Detailed Description

create points lying on isosurface.

Date:

2000/12/10 20:09:15

Revision:

1.38

vtkDividingCubes is a filter that generates points lying on a surface of constant scalar value (i.e., an isosurface). Dense point clouds (i.e., at screen resolution) will appear as a surface. Less dense clouds can be used as a source to generate streamlines or to generate "transparent" surfaces. This filter is based on the generate program written by H. Cline, S. Ludke and W. Lorensen.

The density of the point cloud is controlled by the Distance instance variable. This is a distance value in global coordinates specifying the approximate distance between points.

Member Function Documentation

vtkDividingCubes* vtkDividingCubes::New (    )  [static]

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

virtual const char* vtkDividingCubes::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 vtkStructuredPointsToPolyDataFilter.

int vtkDividingCubes::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 vtkStructuredPointsToPolyDataFilter.

virtual int vtkDividingCubes::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 vtkStructuredPointsToPolyDataFilter.

vtkDividingCubes* vtkDividingCubes::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 vtkStructuredPointsToPolyDataFilter.

void vtkDividingCubes::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 vtkDividingCubes::SetValue (  float    )  [virtual]

Set isosurface value.

virtual float vtkDividingCubes::GetValue (    )  [virtual]

virtual void vtkDividingCubes::SetDistance (  float    )  [virtual]

Specify sub-voxel size at which to generate point.

virtual float vtkDividingCubes::GetDistance (    )  [virtual]

virtual void vtkDividingCubes::SetIncrement (  int    )  [virtual]

Every "Increment" point is added to the list of points. This parameter, if set to a large value, can be used to limit the number of points while retaining good accuracy.

virtual int vtkDividingCubes::GetIncrement (    )  [virtual]

void vtkDividingCubes::operator= (  const vtkDividingCubes &    )  [inline, protected]

Definition at line 105 of file vtkDividingCubes.h.

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

Reimplemented from vtkSource.

void vtkDividingCubes::SubDivide (  float    origin[3], int    dim[3], float    h[3], float    values[8] )  [protected]
