vtkBandedPolyDataContourFilter

Section: Visualization Toolkit Graphics Classes

Usage

vtkBandedPolyDataContourFilter is a filter that takes as input vtkPolyData and produces as output filled contours (also represented as vtkPolyData). Filled contours are bands of cells that all have the same cell scalar value, and can therefore be colored the same. The method is also referred to as filled contour generation.

To use this filter you must specify one or more contour values. You can either use the method SetValue() to specify each contour value, or use GenerateValues() to generate a series of evenly spaced contours. Each contour value divides (or clips) the data into two pieces, values below the contour value, and values above it. The scalar values of each band correspond to the specified contour value. Note that if the first and last contour values are not the minimum/maximum contour range, then two extra contour values are added corresponding to the minimum and maximum range values. These extra contour bands can be prevented from being output by turning clipping on.

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

  obj = vtkBandedPolyDataContourFilter
