Create scaling matrix

pub fn scaling_with_origin(sx: f64, sy: f64, sz: f64, origin: Vector3) -> Self

Create scaling matrix with origin

pub fn rotation_x(angle: f64) -> Self

Create rotation matrix around X axis

pub fn rotation_y(angle: f64) -> Self

Create rotation matrix around Y axis

pub fn rotation_z(angle: f64) -> Self

Create rotation matrix around Z axis

pub fn rotation(axis: Vector3, angle: f64) -> Self

Create rotation matrix around arbitrary axis (Rodrigues’ rotation formula)

pub fn from_matrix3(m3: Matrix3) -> Self

pub fn to_matrix3(&self) -> Matrix3

Get the 3x3 rotation/scale portion

pub fn transpose(&self) -> Self

Transpose the matrix

pub fn transform_point(&self, v: Vector3) -> Vector3

Trait Implementations

impl Clone for Matrix4

fn clone(&self) -> Matrix4

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Matrix4

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Matrix4

fn default() -> Self

Returns the “default value” for a type.

impl Mul for Matrix4

type Output = Matrix4

The resulting type after applying the * operator.

fn mul(self, rhs: Self) -> Self::Output

Performs the * operation.

impl PartialEq for Matrix4

fn eq(&self, other: &Matrix4) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
