vtkGenericSubdivisionErrorMetric

Section: Visualization Toolkit Filtering Classes

Usage

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.

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

  obj = vtkGenericSubdivisionErrorMetric
