Member Function Documentation

CVector3D CVector3D::move	(	const CAngle3D &	ang,
		const unit	f
	)

Create a new vector by moving f units along an angle from the current vector.

Parameters:

	ang	Angle we are moving along.
	f	Distance moved.

Returns:

New vector.

Add a rotated unit vector of length f <f,0,0>

Parameters:

	ang	Angle of rotation
	f	Lenth of movement vector

Returns:

Rotated movement vector

CVector3D CVector3D::move	(	const CAngle3D &	ang,
		const CVector3D &	moveVec
	)

Create a new vector by adding the rotated moveVec to the current vector.

Parameters:

	ang	Angle we are moving along.
	moveVec	Vector to be rotated.

Returns:

New vector.

Add a rotated vector

Parameters:

	ang	Angle of rotation
	moveVec	Movement vector

Returns:

Rotated movement vector

void CVector3D::rotate

(

const CAngle3D &

ang

)

Rotate x,y,z values around origin by angle ang.

Parameters:

ang

Angle used for rotation.

Rotate around origin by CAngle3D ang

Parameters:

ang

Angle of rotation

Note:

angle values are in degrees

Parameters:

ang	rotate x,y,z values around origin by angle ang

void CVector3D::get_array

(

unit

array[]

)

const [inline]

Get vector values as an array.

Parameters:

array

A unit array of at least 3 values.

Note:

Will crash is array is not at least 3 units in size.

unit CVector3D::get_length

(

)

const [inline]

Returns:

The length of this vector.

See also:

get_length_sq()

unit CVector3D::get_length_sq

(

)

const [inline]

Returns:

The length squared of this vector.

Note:

Much quicker than normal get_length().

See also:

get_length()

CVector3D CVector3D::get_normalized

(

const unit

f = 1.0

)

const [inline]

Change the length of the vector (keeping the direction).

Parameters:

f

New length.

Returns:

A normalized vector.
