Types

type Matrix3

type Matrix3 [3][3]float64

Matrix3 is a 3 dimentional matrix

func New3

func New3() Matrix3

New3 returns a new 3x3 identity matrix

func (Matrix3) Determinant

func (m Matrix3) Determinant() float64

Determinant returns the determinant of the matrix

func (*Matrix3) Invert

func (m *Matrix3) Invert()

func (Matrix3) IsAffine

func (m Matrix3) IsAffine() bool

IsAffine checks whether the matrix represents an affine transformation

func (Matrix3) IsIdentity

func (m Matrix3) IsIdentity() bool

IsIdentity checks whether the matrix is an identity matrix: [1, 0, 0

0, 1, 0
