vtkEdgeSubdivisionCriterion

Section: Visualization Toolkit Graphics Classes

Usage

Descendants of this abstract class are used to decide whether a piecewise linear approximation (triangles, lines, ... ) to some nonlinear geometry should be subdivided. This decision may be based on an absolute error metric (chord error) or on some view-dependent metric (chord error compared to device resolution) or on some abstract metric (color error). Or anything else, really. Just so long as you implement the EvaluateEdge member, all will be well.

To create an instance of class vtkEdgeSubdivisionCriterion, simply invoke its constructor as follows

  obj = vtkEdgeSubdivisionCriterion
