TRANSFORM T (const TRANSFORM & T1 )
returns the transformation T ◦ T1 .
POINT
T (const POINT & p) returns T (p).
VECTOR T (const VECTOR& v)
SEGMENT T (const SEGMENT & s)
returns T (v).
returns T (s).
LINE T (const LINE& l) returns T (l).
RAY T (const RAY & r) returns T (r).
CIRCLE T (const CIRCLE& C)
POLYGON T (const POLYGON & P )
returns T (C).
returns T (P ).
GEN POLYGON T (const GEN POLYGON & P )
Non-member Functions
returns T (P ).
In any of the function below a point can be specified to the origin by replacing it by an
anonymous object of type POINT, e.g., rotation90 (POINT ( )) will generate a rotation
about the origin.
TRANSFORM translation(const INT TYPE & dx, const INT TYPE & dy,
const INT TYPE & dw)
returns the translation by the vector (dx/dw, dy/dw).
TRANSFORM translation(const RAT TYPE & dx, const RAT TYPE& dy)
TRANSFORM translation(const VECTOR& v)
returns the translation by the vector (dx, dy).
returns the translation by the vector v.
TRANSFORM rotation(const POINT & q, double alpha, double eps)
TRANSFORM rotation90(const POINT & q)
returns the rotation about q by an angle alpha ± eps.
returns the rotation about q by an angle of 90 degrees.
