generate isosurfaces/isolines from scalar values (specialized for unstructured grids)
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.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void SetNumberOfContours(int number)
Set the number of contours to place into the list.
static vtkContourGrid * New()
Construct object with initial range (0,1) and single contour value of 0.0.
vtkMTimeType GetMTime() override
Modified GetMTime Because we delegate to vtkContourValues.
double GetValue(int i)
Get the ith contour value.
int GetNumberOfContours()
Get the number of contours in the list of contour values.
helper object to manage setting and generating contour values
void SetValue(int i, double value)
Set the ith contour value.
keep track of edges (edge is pair of integer id's)
Definition: vtkEdgeTable.h:41
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.
Superclass for algorithms that produce only polydata as output.
organize data according to scalar values (used to accelerate contouring operations)
