helper object to manage setting and generating contour values
generate isoline(s) from 2D image data
int FillInputPortInformation(int port, vtkInformation *info) override
Fill the input port information objects for this algorithm.
void GetValues(double *contourValues)
Fill a supplied list with contour values.
int RequestData(vtkInformation *, vtkInformationVector **, vtkInformationVector *) override
This is called by the superclass.
void SetNumberOfContours(int number)
Set the number of contours to place into the list.
double * GetValues()
Get a pointer to an array of contour values.
void GenerateValues(int numContours, double range[2])
Generate numContours equally spaced contour values between specified range.
vtkIdType GetNumberOfContours()
Get the number of contours in the list of contour values.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void GenerateValues(int numContours, double rangeStart, double rangeEnd)
Generate numContours equally spaced contour values between specified range.
double GetValue(int i)
Get the ith contour value.
~vtkDiscreteFlyingEdges2D() override
void SetValue(int i, double value)
Set a particular contour value at contour number i.
vtkMTimeType GetMTime() override
Because we delegate to vtkContourValues.
static vtkDiscreteFlyingEdges2D * New()
Standard methods for instantiation, printing, and type information.
