helper object to manage setting and generating contour values
topologically and geometrically regular array of data
Abstract class in support of both point location and point insertion.
a simple class to control print indentation
Definition vtkIndent.h:40
Store zero or more vtkInformation instances.
Store vtkAlgorithm input/output information.
int FillInputPortInformation(int port, vtkInformation *info) override
Fill the input port information objects for this algorithm.
void SetImageRange(int imin, int imax, int jmin, int jmax, int kmin, int kmax)
Set/Get the i-j-k index range which define a plane on which to generate contour lines.
vtkIncrementalPointLocator * Locator
void SetNumberOfContours(int number)
Set the number of contours to place into the list.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void SetLocator(vtkIncrementalPointLocator *locator)
double GetValue(int i)
Get the ith contour value.
int RequestData(vtkInformation *, vtkInformationVector **, vtkInformationVector *) override
This is called by the superclass.
vtkIdType GetNumberOfContours()
Get the number of contours in the list of contour values.
double * GetValues()
Get a pointer to an array of contour values.
vtkMTimeType GetMTime() override
Because we delegate to vtkContourValues.
void GenerateValues(int numContours, double range[2])
Generate numContours equally spaced contour values between specified range.
void SetValue(int i, double value)
Methods to set contour values.
static vtkMarchingSquares * New()
vtkContourValues * ContourValues
void CreateDefaultLocator()
Create default locator.
