extract vtkPolyData cells that lies either entirely inside or outside of a specified implicit functio...
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
vtkExtractPolyDataGeometry(vtkImplicitFunction *f=nullptr)
vtkIdType InsertPointInMap(vtkIdType i, vtkPoints *inPts, vtkPoints *newPts, vtkIdType *pointMap)
When not passing points, have to use a point map to keep track of things.
int RequestData(vtkInformation *, vtkInformationVector **, vtkInformationVector *) override
This is called by the superclass.
~vtkExtractPolyDataGeometry() override
vtkMTimeType GetMTime() override
Return the MTime taking into account changes to the implicit function.
virtual void SetImplicitFunction(vtkImplicitFunction *)
Specify the implicit function for inside/outside checks.
static vtkExtractPolyDataGeometry * New()
Construct object with ExtractInside turned on.
abstract interface for implicit functions
a simple class to control print indentation
Definition: vtkIndent.h:108
Store zero or more vtkInformation instances.
Store vtkAlgorithm input/output information.
represent and manipulate 3D points
Definition: vtkPoints.h:139
vtkIdType InsertNextPoint(const float x[3])
Insert point into next available slot.
Definition: vtkPoints.h:310
double * GetPoint(vtkIdType id)
Return a pointer to a double point x[3] for a specific id.
Definition: vtkPoints.h:239
