Implementations

impl Mat3

pub const ZERO: Self

Zero matrix.

pub const IDENTITY: Self

Identity matrix.

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

Creates a matrix from column vectors.

Creates a diagonal matrix.

pub fn from_scale(scale: Vec2) -> Self

Creates a 2D scaling matrix.

pub fn from_translation(translation: Vec2) -> Self

Creates a 2D translation matrix.

pub fn from_rotation(angle: Float) -> Self

Creates a 2D rotation matrix.

pub fn transpose(self) -> Self

Returns the transpose of this matrix.

pub fn determinant(self) -> Float

Computes the determinant.

pub fn try_inverse(self) -> Option<Self>

Returns the inverse, or None if not invertible.

pub fn inverse(self) -> Self

Returns the inverse.

Panics

Panics if the matrix is not invertible.

pub fn transform(self, v: Vec3) -> Vec3

Transforms a Vec3 by this matrix.

pub fn transform_point2(self, p: Vec2) -> Vec2

Transforms a 2D point (Vec2 with z=1).

pub fn transform_vector2(self, v: Vec2) -> Vec2

Transforms a 2D vector (Vec2 with z=0).

pub fn approx_eq(self, other: Self) -> bool

Checks if this matrix is approximately equal to another.

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 Default for Mat3

fn default() -> Self

Returns the “default value” for a type.

impl Mul<Vec3> for Mat3

type Output = Vec3

The resulting type after applying the * operator.

fn mul(self, v: Vec3) -> Vec3

Performs the * operation.

impl Mul for Mat3

type Output = Mat3

The resulting type after applying the * operator.

fn mul(self, other: Self) -> Self

Performs the * operation.

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.
