vector3d<T> crossProduct

(

const vector3d< T > &

other

)

const [inline]

Calculates the cross product with another vector

Parameters:

other,:

Other vector to get the cross product against.

T dotProduct

(

const vector3d< T > &

other

)

const [inline]

bool equals

(

const vector3d< T > &

other

)

[inline]

void getAs4Values

(

T *

array

)

[inline]

Useful for setting in shader constants for example. The fourth value will always be 0.

f64 getDistanceFrom

(

const vector3d< T > &

other

)

const [inline]

Here, the vector is interpreted as point in 3 dimensional space.

f32 getDistanceFromSQ

(

const vector3d< T > &

other

)

const [inline]

Here, the vector is interpreted as a point in 3 dimensional space.

vector3d<T> getHorizontalAngle

(

)

[inline]

Thanks to Arras on the Irrlicht forums to add this method.

Returns:

A vector representing the rotation in degrees of this vector. The Z component of the vector will always be 0.

vector3d<T> getInterpolated	(	const vector3d< T > &	other,
		f32	d
	)			const [inline]

Returns interpolated vector.

Parameters:

	other,:	other vector to interpolate between
	d,:	value between 0.0f and 1.0f.

f64 getLength

(

)

const [inline]

f64 getLengthSQ

(

)

const [inline]

This is useful because it is much faster then getLength().

void invert

(

)

[inline]

bool isBetweenPoints	(	const vector3d< T > &	begin,
		const vector3d< T > &	end
	)			const [inline]

Returns if this vector interpreted as a point is on a line between two other points. It is assumed that the point is on the line.

Parameters:

	begin,:	Begin point to check between.
	end,:	End point to check between.
