Detailed Description
generate isocontours from input dataset
vtkGenericContourFilter is a filter that takes as input any (generic) dataset and generates on output isosurfaces and/or isolines. The exact form of the output depends upon the dimensionality of the input data. Data consisting of 3D cells will generate isosurfaces, data consisting of 2D cells will generate isolines, and data with 1D or 0D cells will generate isopoints. Combinations of output type are possible if the input dimension is mixed.
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. You can use ComputeNormalsOn to compute the normals without the need of a vtkPolyDataNormals
This filter has been implemented to operate on generic datasets, rather than the typical vtkDataSet (and subclasses). vtkGenericDataSet is a more complex cousin of vtkDataSet, typically consisting of nonlinear, higher-order cells. To process this type of data, generic cells are automatically tessellated into linear cells prior to isocontouring.

| virtual void vtkGenericContourFilter::SetComputeNormals | ( | int | ) | [virtual] |
Set/Get the computation of normals. Normal computation is fairly expensive in both time and storage. If the output data will be processed by filters that modify topology or geometry, it may be wise to turn Normals and Gradients off.
