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

Parameters
valuesA 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
valuesA 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
matrixThe matrix to multiply the receiver with

◆ scaleWithVector:()

- (void) scaleWithVector: (OFVector3D vector

Scales the matrix with the specified vector.

Parameters
vectorThe vector to scale the matrix with

◆ transformedVector:()
