Objects that compute error during cell tessellation.
a simple class to control print indentation
Definition: vtkIndent.h:38
Objects that compute geometry-based error during cell tessellation according to some max angle.
void PrintSelf(ostream &os, vtkIndent indent) override
Standard VTK type and error macros.
~vtkSmoothErrorMetric() override
static vtkSmoothErrorMetric * New()
Construct the error metric with a default flatness threshold of 90.1 degrees.
double GetAngleTolerance()
Return the flatness threshold.
void SetAngleTolerance(double value)
Set the flatness threshold with an angle in degrees.
int RequiresEdgeSubdivision(double *leftPoint, double *midPoint, double *rightPoint, double alpha) override
