The module is based on "ISF_91_2_TP" algorithm developed by v4w.enko The other layer of the structure. Technical abstract description of the parametric form: ISF_91_2_TP - Custom transformations of three iso-surfaces [ISF] are based on evaluation of random ellipsoid paths. Faces are 'turned' to micro-cubes in connection with re-parametrized line segments. Volume is subtracted with hexagonal prism. 3D extrusion.
