POLYGON
n gon(int n, CIRCLE C, double epsilon)
generates a (nearly) regular n-gon whose
vertices lie near the circle C. For the flaoting
point kernel the function is equivalent to the
function above. For the rational kernel the
function first generates a n-gon with floating
point arithmetic and then converts the
resulting polygon to a rat polygon.
POLYGON hilbert(int n, RAT TYPE x1 , RAT TYPE y1 , RAT TYPE x2 ,
RAT TYPE y2 )
generates the Hilbert polygon of order n
within the rectangle with boundary (x1 , y1 )
and (x2 , y2 ).
Precondition: x1 < x2 and y1 < y2 .
