double Length

(

const DPoint3 &

v

)

[inline]

Search for all occurrences

Remarks:

Returns the 'Length' of the point. This is sqrt(v.x*v.x+v.y*v.y+v.z*v.z)

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

int MaxComponent

(

const DPoint3 &

)

Search for all occurrences

Remarks:

Returns the component with the maximum absolute value. 0=x, 1=y, 2=z.

int MinComponent

(

const DPoint3 &

)

Search for all occurrences

Remarks:

Returns the component with the minimum absolute value. 0=x, 1=y, 2=z.

DPoint3 Normalize

(

const DPoint3 &

)

Search for all occurrences

Remarks:

Returns a unit vector. This is a DPoint3 with each component divided by the point Length().

DPoint3 operator*	(	double	f,
		const DPoint3 &	a
	)		[inline]

                                                     {
        return(DPoint3(a.x*f, a.y*f, a.z*f));
        }

DPoint3 operator*	(	const DPoint3 &	a,
		double	f
	)		[inline]

                                                     {
        return(DPoint3(a.x*f, a.y*f, a.z*f));
        }

DPoint3 operator/	(	const DPoint3 &	a,
		double	f
	)		[inline]

                                                     {
        return(DPoint3(a.x/f, a.y/f, a.z/f));
        }

std::ostream& operator<<	(	std::ostream &	,
		const DPoint3 &
	)

DPoint3 CrossProd	(	const DPoint3 &	a,
		const DPoint3 &	b
	)

Search for all occurrences

Remarks:

Returns the cross product of two DPoint3s.

double DotProd	(	const DPoint3 &	a,
		const DPoint3 &	b
	)

Search for all occurrences

Remarks:

Returns the dot product of two DPoint3s.
