Function Documentation

Point2 operator+	(	const Point2 &	a,
		float	f
	)

inline

Remarks: Returns a copy of the Point2 argument offset by (f, f).

                                                   {
    return(Point2(a.x+f, a.y+f));
    }

float Length ( const Point2 & v )

inline

Remarks: Returns the length of the Point2, ie:

sqrt(v.x*v.x+v.y*v.y);

                                      {  
     return (float)sqrt(v.x*v.x+v.y*v.y);
     }

int MaxComponent ( const Point2 & )

Remarks: Returns the component with the maximum absolute value. 0=x, 1=y.

int MinComponent ( const Point2 & )

Remarks: Returns the component with the minimum absolute value. 0=x, 1=y.

Point2 Normalize ( const Point2 & )

Remarks: Returns a unit vector. This is a Point2 with each component divided by the point Length().

Point2 operator*	(	float	f,
		const Point2 &	a
	)

inline

Remarks: Returns a Point2 multiplied by a scalar.

                                                   {
     return(Point2(a.x*f, a.y*f));
     }

Point2 operator*	(	const Point2 &	a,
		float	f
	)

inline

Remarks: Returns a Point2 multiplied by a scalar.

                                                   {
     return(Point2(a.x*f, a.y*f));
     }

Point2 operator/	(	const Point2 &	a,
		float	f
	)

inline

Remarks: Returns a Point2 whose x and y members are divided by a scalar.

                                                   {
     DbgAssert(f != 0.0f);
     float invF = 1.0f / f;  // Mimic 2019 behavior
     return(Point2(a.x * invF, a.y * invF));
     }

M_STD_OSTREAM& operator<<	(	M_STD_OSTREAM &	,
		const Point2 &
	)

float LengthSquared ( const Point2 & v )

inline

Remarks: The 'Length' squared of the point. This is v.x*v.x+v.y*v.y.

                                             {   
     return (float)(v.x*v.x+v.y*v.y);
     }
