Detailed Description

generate isosurfaces/isolines from scalar values

use of unsigned short to hold level index limits tree depth to 16.

To use this filter you must specify one or more contour values. You can either use the method SetValue() to specify each contour value, or use GenerateValues() to generate a series of evenly spaced contours. It is also possible to accelerate the operation of this filter (at the cost of extra memory) by using a vtkScalarTree. A scalar tree is used to quickly locate cells that contain a contour surface. This is especially effective if multiple contours are being extracted. If you want to use a scalar tree, invoke the method UseScalarTreeOn().

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

Reimplemented from vtkPolyDataAlgorithm.

static int vtkHyperOctreeDualGridContourFilter::IsTypeOf ( const char *  name  )  [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 vtkHyperOctreeDualGridContourFilter::IsA ( const char *  name  )  [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 vtkHyperOctreeDualGridContourFilter* vtkHyperOctreeDualGridContourFilter::SafeDownCast ( vtkObject o  )  [static]

Reimplemented from vtkPolyDataAlgorithm.

void vtkHyperOctreeDualGridContourFilter::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.

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

Construct object with initial range (0,1) and single contour value of 0.0.

Reimplemented from vtkPolyDataAlgorithm.

void vtkHyperOctreeDualGridContourFilter::SetValue ( int  i,
double  value 
) [inline]

Methods to set / get contour values.

Set a particular contour value at contour number i. The index i ranges between 0<=i<NumberOfContours.

Definition at line 74 of file vtkHyperOctreeDualGridContourFilter.h.

double vtkHyperOctreeDualGridContourFilter::GetValue ( int  i  )  [inline]

Get the ith contour value.

Definition at line 82 of file vtkHyperOctreeDualGridContourFilter.h.

double* vtkHyperOctreeDualGridContourFilter::GetValues (  )  [inline]

Get a pointer to an array of contour values. There will be GetNumberOfContours() values in the list.

Definition at line 91 of file vtkHyperOctreeDualGridContourFilter.h.

void vtkHyperOctreeDualGridContourFilter::GetValues ( double *  contourValues  )  [inline]

Fill a supplied list with contour values. There will be GetNumberOfContours() values in the list. Make sure you allocate enough memory to hold the list.

Definition at line 101 of file vtkHyperOctreeDualGridContourFilter.h.

void vtkHyperOctreeDualGridContourFilter::SetNumberOfContours ( int  number  )  [inline]

Set the number of contours to place into the list. You only really need to use this method to reduce list size. The method SetValue() will automatically increase list size as needed.

Definition at line 111 of file vtkHyperOctreeDualGridContourFilter.h.

int vtkHyperOctreeDualGridContourFilter::GetNumberOfContours (  )  [inline]

Get the number of contours in the list of contour values.

Definition at line 119 of file vtkHyperOctreeDualGridContourFilter.h.

void vtkHyperOctreeDualGridContourFilter::GenerateValues ( int  numContours,
double  range[2] 
) [inline]

Generate numContours equally spaced contour values between specified range. Contour values will include min/max range values.

Definition at line 128 of file vtkHyperOctreeDualGridContourFilter.h.

void vtkHyperOctreeDualGridContourFilter::GenerateValues ( int  numContours,
double  rangeStart,
double  rangeEnd

Generate numContours equally spaced contour values between specified range. Contour values will include min/max range values.

Definition at line 137 of file vtkHyperOctreeDualGridContourFilter.h.

unsigned long vtkHyperOctreeDualGridContourFilter::GetMTime (  )  [virtual]

Modified GetMTime Because we delegate to vtkContourValues
