var Identity = Matrix{
	{1, 0, 0, 0},
	{0, 1, 0, 0},
	{0, 0, 1, 0},
	{0, 0, 0, 1},
}

Identity can be multiplied by another matrix to produce the same matrix.

type Matrix [4]vec32.Vector

Matrix holds a 4x4 matrix. Each vector is a column of the matrix.

func Mul(m1, m2 Matrix) Matrix

Mul multiplies m1 by m2.

func (m Matrix) Rotate(angle float32, axis vec32.Vector) Matrix

Rotate post-multiplies a rotation around an axis. The angle is in radians and the axis will be normalized.

func (m Matrix) Scale(scale vec32.Vector) Matrix

Scale post-multiplies a scale and returns the result.

func (m Matrix) String() string

func (m Matrix) Transform(u vec32.Vector) (v vec32.Vector)

Transform multiplies m by u.

func (m Matrix) Translate(v vec32.Vector) Matrix

Translate post-multiplies a translation by v and returns the result.

func (m Matrix) Transpose() Matrix

Transpose performs a matrix transposition.
