Function Documentation

Vec3D operator*	(	const Mdouble	a,
		const Vec3D &	b
	)

Multiplies each element of a given vector (b) by a given scalar (a). NB: this is a global function and a friend of the Vec3D class. Gets called when a scalar multiplication of the form (Mdouble) * (Vec3D) is performed.

Parameters

[in]	a	the scalar
[in]	b	the vector

Returns

the resulting vector

{
    return Vec3D(b.X * a, b.Y * a, b.Z * a);
}

Vec3D operator-

(

const Vec3D &

a

)

Returns the negative of a given vector. NB: this is a global function and a friend of the Vec3D class. Gets called when a negation operation of the form - (Vec3D) is performed.

Parameters

[in]

a

the vector to be negated

Returns

the negated vector

{
    return Vec3D(-a.X, -a.Y, -a.Z);
}

std::ostream& operator<<	(	std::ostream &	os,
		const Vec3D &	a
	)

Adds all elements of the vector to an output stream. NB: this is a global function and a friend of the Vec3D class!

Parameters

[in]	os	the output stream,
[in]	a	The vector of interest

Returns

the output stream with vector elements added

{
    os << a.X << ' ' << a.Y << ' ' << a.Z;
    return os;
}

std::istream& operator>>	(	std::istream &	is,
		Vec3D &	a
	)

Reads all elements of a given vector from an input stream. NB: this is a global function and a friend of the Vec3D class!

Parameters

[in,out]	is	the input stream
[in,out]	a	the vector to be read in

Returns

the input stream from which the vector elements were read
