Detailed Description

create points lying on isosurface (using recursive approach).

Date:

2000/12/10 20:08:50

Revision:

1.30

vtkRecursiveDividingCubes 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 implementation differs from vtkDividingCubes in that it uses a recursive procedure. In many cases this can result in generating more points than the procedural implementation of vtkDividingCubes. This is because the recursive procedure divides voxels by multiples of powers of two. This can over-constrain subdivision. One of the advantages of the recursive technique is that the recursion is terminated earlier, which in some cases can be more efficient.

Member Function Documentation

vtkRecursiveDividingCubes* vtkRecursiveDividingCubes::New (    )  [static]

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

virtual const char* vtkRecursiveDividingCubes::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 vtkRecursiveDividingCubes::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 vtkRecursiveDividingCubes::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.

vtkRecursiveDividingCubes* vtkRecursiveDividingCubes::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 vtkRecursiveDividingCubes::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 vtkRecursiveDividingCubes::SetValue (  float    )  [virtual]

Set isosurface value.

virtual float vtkRecursiveDividingCubes::GetValue (    )  [virtual]

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

Specify sub-voxel size at which to generate point.

virtual float vtkRecursiveDividingCubes::GetDistance (    )  [virtual]

virtual void vtkRecursiveDividingCubes::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 vtkRecursiveDividingCubes::GetIncrement (    )  [virtual]

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

Definition at line 96 of file vtkRecursiveDividingCubes.h.

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

Reimplemented from vtkSource.

void vtkRecursiveDividingCubes::SubDivide (  float    origin[3], float    h[3], float    values[8] )  [protected]
