Objects that compute error during cell tessellation.
Objects of that class answer the following question during the cell subdivision: "does the edge need to be subdivided?" through RequiresEdgeSubdivision(). The answer depends on the criterium actually used in the subclass of this abstract class: a geometric-based error metric (variation of edge from a straight line), an attribute-based error metric (variation of the active attribute/component value from a linear ramp) , a view-depend error metric, ... Cell subdivision is performed in the context of the adaptor framework: higher-order, or complex cells, are automatically tessellated into simplices so that they can be processed with conventional visualization algorithms.

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.

Does the edge need to be subdivided according to the implemented computation? 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)
Implemented in vtkAttributesErrorMetric, vtkViewDependentErrorMetric, vtkGeometricErrorMetric, and vtkSmoothErrorMetric.

Return the error at the mid-point.
The type of error depends on the state of the concrete error metric. For instance, it can return an absolute or relative error metric. See RequiresEdgeSubdivision() for a description of the arguments.
Implemented in vtkAttributesErrorMetric, vtkViewDependentErrorMetric, vtkGeometricErrorMetric, and vtkSmoothErrorMetric.
