Detailed Description

generate isosurfaces/isolines from scalar values (specialized for unstructured grids)

vtkContourGrid is a filter that takes as input datasets of type vtkUnstructuredGrid 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. It is also possible to accelerate the operation of this filter (at the cost of extra memory) by using a vtkScalarTree. A scalar tree is used to quickly locate cells that contain a contour surface. This is especially effective if multiple contours are being extracted. If you want to use a scalar tree, invoke the method UseScalarTreeOn().

Warning: For unstructured data or structured grids, normals and gradients are not computed. Use vtkPolyDataNormals to compute the surface normals of the resulting isosurface.
