|
|
* @brief generate points on isosurface
|
|
*
|
|
* 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.
|
|
* @warning
|
|
* 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.
