<a class="el" href="a00451.html" title="generate points on isosurface">vtkEdgePoints</a> 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. <dl class="warning" compact><dt><b>Warning:</b></dt><dd><a class="el" href="a00451.html" title="generate points on isosurface">vtkEdgePoints</a> 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.</dd></dl>
