helper object to manage setting and generating contour values
generate isocontours from input dataset
void GenerateValues(int numContours, double rangeStart, double rangeEnd)
void CreateDefaultLocator()
Create default locator.
void GetValues(double *contourValues)
int RequestData(vtkInformation *, vtkInformationVector **, vtkInformationVector *) override
This is called by the superclass.
void SetNumberOfContours(int number)
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void SetLocator(vtkIncrementalPointLocator *locator)
Set / get a spatial locator for merging points.
~vtkGenericContourFilter() override
double GetValue(int i)
static vtkGenericContourFilter * New()
Construct object with initial range (0,1) and single contour value of 0.0.
vtkIncrementalPointLocator * Locator
vtkMTimeType GetMTime() override
