Public Member Functions  
Line2D ()  
Constructor.  
Line2D (const rw::math::Vector2D<> &p1, const rw::math::Vector2D<> &p2)  
Creates a line between that intersect the two points p1 and p2. More...  
Line2D (double x1, double y1, double x2, double y2)  
Creates a line between that intersect the two points (x1,y1) and (x2,y2). More...  
virtual  ~Line2D () 
Destructor.  
IntersectResult  getIntersect (const Line2D &line, rw::math::Vector2D<> &res) const 
calculates the intersection between two lines. A intersection point is only saved in res if the two lines are not parallel or coincident. The intersection test does not take the segments into acount. More...  
double  calcAngle (const Line2D &line) const 
calculates the angle between this line and line More...  
double  calcAngle () const 
calculates the angle between the projection of this line onto yzplane and the xaxis More...  
double  calcDist (const rw::math::Vector2D<> &v) const 
calculates the shortest distance between point v and the infinite line. More...  
double  getLength () const 
gets the length of thi line segment. More...  
rw::math::Vector2D &  p1 () 
first point on the line  
const rw::math::Vector2D &  p1 () const 
first point on the line More...  
rw::math::Vector2D &  p2 () 
second point on the line  
const rw::math::Vector2D &  p2 () const 
second point on the line More...  
rw::math::Vector2D  calcUnitNormal () const 
calculates the unit normal of the line
