QuadrilateralC()

Creates the empty quadrilateral in the origin of coordinate system.

QuadrilateralC(const Point2dC & a,const Point2dC & b,const Point2dC & c,const Point2dC & d)

Creates the quadrilateral.

QuadrilateralC(const IntRectangleTPC & rect)

Creates the quadrilateral from the rectangle which is determined by the direction and 4 touching points. The result quadrilateral contains 4 points equal to the corners of the original rectangle.

QuadrilateralC(const Point2dC pt[])

Creates the quadrilateral from the arrray of 4 points.

void Set(const Point2dC & a,const Point2dC & b,const Point2dC & c,const Point2dC & d)

Sets the new value of the quadrilateral.

const Point2dC & operator[](IndexT i) const

Returns the point with the index 'i'. The first point has the index 0;
