  abstract = "“Dual contouring” approaches provide an alternative
               to standard Marching Cubes (MC) method to extract
               and approximate an isosurface from trivariate data
               given on a volumetric mesh. These dual approaches
               solve some of the problems encountered by the MC
               methods. We present a simple method based on the
               MC method and the ray intersection technique to compute
               isosurface points in the cell interior. One of the
               advantages of our method is that it does not require us
               to use Hermite interpolation scheme, unlike other dual
               contouring methods. We perform a complete analysis
               of all possible configurations to generate a look-up
               table for all configurations. We use the look-up table
               to optimize the ray-intersection method to obtain
               minimum number of points necessarily sufficient for
               defining topologically correct isosurfaces in all possible
               configurations. Isosurface points are connected
               using a simple strategy."
