Struct Mat3 

#[non_exhaustive]
pub struct Mat3 {
    pub m: [[f64; 3]; 3],
}

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

m: [[f64; 3]; 3]

Row-major: m[row][col]

Implementations

impl Mat3

pub const IDENTITY: Self

pub const ZERO: Self

pub const fn new(m: [[f64; 3]; 3]) -> Self

pub fn from_cols(c0: Vec3, c1: Vec3, c2: Vec3) -> Self

pub fn transform_point(&self, v: Vec2) -> Vec2

Matrix × vector (homogeneous 2D: Vec2 → Vec2 via w=1)

pub fn transform_dir(&self, v: Vec2) -> Vec2

Transform direction (ignores translation)

pub fn mul(&self, rhs: &Self) -> Self

Matrix × matrix

pub fn transpose(&self) -> Self

pub fn determinant(&self) -> f64

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

Inverse via cofactor matrix. Returns None if singular.

Trait Implementations

impl Clone for Mat3

fn clone(&self) -> Mat3

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mat3

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

Formats the value using the given formatter.

impl PartialEq for Mat3

fn eq(&self, other: &Mat3) -> 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.
