// .NAME vtkEdgePoints - generate points on isosurface
|
||
|
|
// .SECTION Description
|
||
|
|
// vtkEdgePoints is a filter that takes as input any dataset and
|
||
|
|
// generates for output a set of points that lie on an isosurface. The
|
||
|
|
// points are created by interpolation along cells edges whose end-points are
|
||
|
|
// below and above the contour value.
|
||
|
|
// .SECTION Caveats
|
||
|
|
// vtkEdgePoints can be considered a "poor man's" dividing cubes algorithm
|
||
|
|
// (see vtkDividingCubes). Points are generated only on the edges of cells,
|
||
|
|
// not in the interior, and at lower density than dividing cubes. However, it
|
||
|
|
// is more general than dividing cubes since it treats any type of dataset.
