Objects that compute attribute-based error during cell tessellation.
void SetAttributeTolerance(double value)
Set the relative attribute accuracy to ‘value’.

double GetError(double *leftPoint, double *midPoint, double *rightPoint, double alpha) override
Return the error at the mid-point.
int RequiresEdgeSubdivision(double *leftPoint, double *midPoint, double *rightPoint, double alpha) override
Does the edge need to be subdivided according to the distance between the value of the active attribu...
static vtkAttributesErrorMetric * New()
Construct the error metric with a default relative attribute accuracy equal to 0.1.
vtkGenericAttributeCollection * AttributeCollection
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void ComputeSquareAbsoluteAttributeTolerance()
Compute the square absolute attribute tolerance, only if the cached value is obsolete.
vtkTimeStamp SquareAbsoluteAttributeToleranceComputeTime
void SetAbsoluteAttributeTolerance(double value)
Set the absolute attribute accuracy to ‘value’.
