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().

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

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 75 of file vtkHyperOctreeDualGridContourFilter.h.

double vtkHyperOctreeDualGridContourFilter::GetValue ( int  i)
inline

Get the ith contour value.

Definition at line 83 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 92 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 102 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 112 of file vtkHyperOctreeDualGridContourFilter.h.

int vtkHyperOctreeDualGridContourFilter::GetNumberOfContours ( )
inline

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

Definition at line 120 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 129 of file vtkHyperOctreeDualGridContourFilter.h.

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

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

unsigned long vtkHyperOctreeDualGridContourFilter::GetMTime ( )

Modified GetMTime Because we delegate to vtkContourValues

void vtkHyperOctreeDualGridContourFilter::SetLocator ( vtkIncrementalPointLocator *  locator)

void vtkHyperOctreeDualGridContourFilter::CreateDefaultLocator ( )

Create default locator. Used to create one when none is specified. The locator is used to merge coincident points.
