Method Documentation

◆ initWithValues:

- (instancetype) initWithValues: (const float [ 4][4]) values

Initializes an already allocated 4x4 matrix with the specified values.

Parameters

values A 2D array of 4x4 floats in row-major format

Returns: An initialized OFMatrix4x4

◆ matrixWithValues:

+ (instancetype) matrixWithValues: (const float [ 4][4]) values

Creates a new 4x4 matrix with the specified values.

Parameters

values A 2D array of 4x4 floats in row-major format

Returns: A new, autoreleased OFMatrix4x4

◆ multiplyWithMatrix:

- (void) multiplyWithMatrix: (OFMatrix4x4 *) matrix

Multiplies the receiver with the specified matrix on the left side and the receiver on the right side.

Parameters

matrix The matrix to multiply the receiver with

◆ scaleWithVector:
