Objects that compute geometry-based error during cell tessellation according to some max angle.
It is a concrete error metric, based on a geometric criterium: a max angle between the chord passing through the midpoint and one of the endpoints and the other chord passing through the midpoint and the other endpoint of the edge. It is related to the flatness of an edge.

Return 1 if this class is the same type of (or a subclass of) the named class.
Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Methods invoked by print to print information about the object including superclasses.
Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkGenericSubdivisionErrorMetric.
double vtkSmoothErrorMetric::GetAngleTolerance | ( | ) |
Return the flatness threshold.
void vtkSmoothErrorMetric::SetAngleTolerance | ( | double | value | ) |
Set the flatness threshold with an angle in degrees.
Internally compute the cosine. value is supposed to be in ]90,180[, if not it is clamped in [90.1,179.9]. For instance 178 will give better result than 150.

Does the edge need to be subdivided according to the cosine between the two chords passing through the mid-point and the endpoints? The edge is defined by its ‘leftPoint’ and its ‘rightPoint’.
‘leftPoint’, ‘midPoint’ and ‘rightPoint’ have to be initialized before calling RequiresEdgeSubdivision(). Their format is global coordinates, parametric coordinates and point centered attributes: xyx rst abc de... ‘alpha’ is the normalized abscissa of the midpoint along the edge. (close to 0 means close to the left point, close to 1 means close to the right point)
Implements vtkGenericSubdivisionErrorMetric.

overridevirtual |
Return the error at the mid-point.
It will return an error relative to the bounding box size if GetRelative() is true, a square absolute error otherwise. See RequiresEdgeSubdivision() for a description of the arguments.
