Developed mathematical models and algorithms allow the synthesis of arbitrary surfaces without triangulation. Synthesized surfaces are smooth and contain no ribbing. This simplifies the lighting and shading calculations in contrast to polygonal surface approximation with illumination interpolation (i.e. Gouraud or Phong ). Terrain reconstruction is based on the digital elevation data. Reconstruction is done on the fly and doesn't demand subsidiary data.
