  • static inline Number det( Vector2Math<Number> const &a, Vector2Math<Number> const &b, Vector2Math<Number> const &c);
    Returns twice the area of the oriented triangle (a, b, c), i.e., the area is positive if the triangle is oriented counterclockwise.
  • static inline bool ccw( Vector2Math<Number> const &a, Vector2Math<Number> const &b, Vector2Math<Number> const &c);
    Returns true if the points a, b, c are in a counterclockwise order

    Returns true if the points a, b, c are in a clockwise order
  • static inline Number angle( Vector2Math<Number> const &a, Vector2Math<Number> const &b );
  • static inline Number angle( Vector2Math<Number> const &a, Vector2Math<Number> const &o, Vector2Math<Number> const &b );

  • static Vector2Math<Number> circumcenter( Vector2Math<Number> const & a, Vector2Math<Number> const & b, Vector2Math<Number> const & c);
    Returns the center of the circle through points a, b, c.
  • static inline bool same_side( Vector2Math<Number> const &a, Vector2Math<Number> const &b, Vector2Math<Number> const &x, Vector2Math<Number> const &y );
  • static inline bool opposite( Vector2Math<Number> const &a, Vector2Math<Number> const &b, Vector2Math<Number> const &x, Vector2Math<Number> const &y );
