Detailed Description

generate filled contours for vtkPolyData

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.

Methods to set / get contour values. A single value at a time can be set with SetValue(). Multiple contour values can be set with GenerateValues(). Note that GenerateValues() generates n values inclusive of the start and end range values.

Set a particular contour value at contour number i. The index i ranges between 0<=i<NumberOfContours.

Indicate whether to clip outside the range specified by the user. (The range is contour value[0] to contour value[numContours-1].) Clipping means all cells outside of the range specified are not sent to the output.

virtual int vtkBandedPolyDataContourFilter::GetClipping ( )

virtual void vtkBandedPolyDataContourFilter::SetScalarMode ( int )

virtual

Control whether the cell scalars are output as an integer index or a scalar value. If an index, the index refers to the bands produced by the clipping range. If a value, then a scalar value which is a value between clip values is used.

virtual int vtkBandedPolyDataContourFilter::GetScalarMode ( )

virtual void vtkBandedPolyDataContourFilter::SetGenerateContourEdges ( int )

virtual void vtkBandedPolyDataContourFilter::SetClipTolerance ( double )
