Fields

m: [[f64; 3]; 3]

Matrix elements stored in row-major order

Implementations

impl Matrix3

pub fn identity() -> Self

Create identity matrix

pub fn zero() -> Self

Create zero matrix

pub fn from_rows(row0: [f64; 3], row1: [f64; 3], row2: [f64; 3]) -> Self

Create matrix from rows

pub fn rotation_z(angle: f64) -> Self

Create rotation matrix around Z axis

pub fn scaling(sx: f64, sy: f64, sz: f64) -> Self

Create scaling matrix

pub fn arbitrary_axis(normal: Vector3) -> Self

Create arbitrary axis matrix for OCS to WCS conversion

pub fn transpose(&self) -> Self

Transpose the matrix

pub fn determinant(&self) -> f64

Calculate determinant

pub fn inverse(&self) -> Option<Self>

Invert the matrix (returns None if singular)

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

Transform a Vector3

Trait Implementations

impl Clone for Matrix3

fn clone(&self) -> Matrix3

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Matrix3

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

Formats the value using the given formatter.

impl Default for Matrix3

fn default() -> Self

Returns the “default value” for a type.

impl Mul<Vector3> for Matrix3

type Output = Vector3

The resulting type after applying the * operator.

fn mul(self, v: Vector3) -> Self::Output

Performs the * operation.

impl Mul for Matrix3

type Output = Matrix3

The resulting type after applying the * operator.

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

Performs the * operation.

impl PartialEq for Matrix3

fn eq(&self, other: &Matrix3) -> 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.
