// .NAME vtkExtractGeometry - extract cells that lie either entirely inside or outside of a specified implicit function
|
|
|
|
// .SECTION Description
|
|
// vtkExtractGeometry extracts from its input dataset all cells that are either
|
|
// completely inside or outside of a specified implicit function. Any type of
|
|
// dataset can be input to this filter. On output the filter generates an
|
|
// unstructured grid.
|
|
//
|
|
// To use this filter you must specify an implicit function. You must also
|
|
// specify whethter to extract cells lying inside or outside of the implicit
|
|
// function. (The inside of an implicit function is the negative values
|
|
// region.) An option exists to extract cells that are neither inside or
|
|
// outside (i.e., boundary).
|
|
//
|
|
// A more efficient version of this filter is available for vtkPolyData input.
|
|
// See vtkExtractPolyDataGeometry.
