abstract class to specify dataset behavior
Definition: vtkDataSet.h:57
Detect and break reference loops.
treat a dataset as if it were an implicit function
virtual void SetDataSet(vtkDataSet *)
Set / get the dataset used for the implicit function evaluation.
vtkMTimeType GetMTime() override
Return the MTime also considering the DataSet dependency.
double EvaluateFunction(double x[3]) override
Evaluate function at position x-y-z and return value.
void ReportReferences(vtkGarbageCollector *) override
void EvaluateGradient(double x[3], double n[3]) override
Evaluate implicit function gradient.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
static vtkImplicitDataSet * New()
Construct an vtkImplicitDataSet with no initial dataset; the OutValue set to a large negative number;...
~vtkImplicitDataSet() override
abstract interface for implicit functions
virtual double EvaluateFunction(double x[3])=0
Evaluate function at position x-y-z and return value.
