Detailed Description

An ARVector4 is a 4-Dimensional vector consisting of an X, Y, Z and W component. Generally used for graphical shading.

Method Documentation

- (ARVector4 *) addVector:

(ARVector4 *)

vector

Add this vector to another vector and return the result.

Parameters

vector

The vector to add to this vector.

Returns

The sum of the vectors.

- (ARVector4 *) localAddVector:

(ARVector4 *)

vector

Add this vector to another vector and store the result in this vector.

Parameters

vector

The vector to add to this vector.

Returns

This vector, now the sum of the two vectors.

+ (ARVector4 *) vectorWithValuesX:		(float)	x
y:		(float)	y
z:		(float)	z
w:		(float)	w

Create a vector with the specified component values.

Example of use:

ARVector4 *vector = [ARVector4 vectorWithValuesX:1 y:0 z:1 w:0];

Parameters

x	The x component of the vector.
y	The y component of the vector.
z	The z component of the vector.
w	The w component of the vector.

Returns

A vector with components set to the specified values.

+ (ARVector4 *) vectorWithZero

Create a vector with all 4 components set to 0.

Example of use:

ARVector4 *vector = [ARVector4 vectorWithZero];

Returns

A vector with (0, 0, 0, 0)
