60.4 Definitions for Koch snowflakes
====================================

 -- Function: snowmap (<ent>, <nn>)

     Koch snowflake sets.  Function 'snowmap' plots the snow Koch map
     over the vertex of an initial closed polygonal, in the complex
     plane.  Here the orientation of the polygon is important.  Argument
     <nn> is the number of recursive applications of Koch
     transformation; <nn> must be small (5 or 6).

     Examples:

          (%i1) load("fractals")$
          (%i2) plot2d([discrete,
                        snowmap([1,exp(%i*%pi*2/3),exp(-%i*%pi*2/3),1],4)])$
          (%i3) plot2d([discrete,
                        snowmap([1,exp(-%i*%pi*2/3),exp(%i*%pi*2/3),1],4)])$
          (%i4) plot2d([discrete, snowmap([0,1,1+%i,%i,0],4)])$
          (%i5) plot2d([discrete, snowmap([0,%i,1+%i,1,0],4)])$
