circle gen polygon P (KIND k);
creates a polygon P of kind k, where k is either EMPTY or FULL.
r circle gen polygon P (const list& seg chain,
CHECK TYPE check = WEAKLY SIMPLE ,
RESPECT TYPE respect orient =
RESPECT ORIENTATION );
creates a polygon P from a single closed chain of segments.
r circle gen polygon P (const r circle polygon& Q,
CHECK TYPE check = NO CHECK ,
RESPECT TYPE respect orient =
RESPECT ORIENTATION );
converts an r circle polygon Q to an r circle gen polygon P .
r circle gen polygon P (const list& L,
CHECK TYPE check = NO CHECK ,
RESPECT TYPE respect orient =
RESPECT ORIENTATION );
creates a polygon P with straight line edges from a list L of vertices.
r circle gen polygon P (const list& polys,
CHECK TYPE check = NO CHECK ,
RESPECT TYPE respect orient =
RESPECT ORIENTATION );
introduces a variable P of type r circle gen polygon. P is initialized
to the polygon with boundary representation polys.
Precondition: polys must be a boundary representation.
r circle gen polygon P (const rat gen polygon& Q,
CHECK TYPE check = NO CHECK ,
RESPECT TYPE respect orient =
RESPECT ORIENTATION );
converts a rat gen polygon Q to an r circle gen polygon P .
r circle gen polygon P (const gen polygon& Q, CHECK TYPE check = NO CHECK ,
RESPECT TYPE respect orient =
RESPECT ORIENTATION ,
int prec = rat point :: default precision);
converts the (floating point) gen polygon Q to an
r circle gen polygon. P is initialized to a rational approximation
of Q of coordinates with denominator at most prec. If prec
is zero, the implementation chooses prec large enough such that
there is no loss of precision in the conversion.
