create points laying on isosurface (using recursive approach)
vtkRecursiveDividingCubes is a filter that generates points laying on a surface of constant scalar value (i.e., an isosurface). Dense point clouds (i.e., at screen resolution) will appear as a surface. Less dense clouds can be used as a source to generate streamlines or to generate "transparent" surfaces.
This implementation differs from vtkDividingCubes in that it uses a recursive procedure. In many cases this can result in generating more points than the procedural implementation of vtkDividingCubes. This is because the recursive procedure divides voxels by multiples of powers of two. This can over-constrain subdivision. One of the advantages of the recursive technique is that the recursion is terminated earlier, which in some cases can be more efficient.
