abstract interface for implicit functions
virtual double EvaluateFunction(double x[3])=0
Evaluate function at position x-y-z and return value.
implicit function for a selection loop
void PrintSelf(ostream &os, vtkIndent indent) override
Standard VTK methods for printing and type information.
vtkMTimeType GetMTime() override
Overload GetMTime() because we depend on the Loop.
void EvaluateGradient(double x[3], double n[3]) override
Evaluate selection loop returning the gradient.
~vtkImplicitSelectionLoop() override
double EvaluateFunction(double x[3]) override
Evaluate selection loop returning a signed distance.
static vtkImplicitSelectionLoop * New()
Instantiate object with no initial loop.
virtual void SetLoop(vtkPoints *)
Set/Get the array of point coordinates defining the loop.
