Struct Mat3 

pub struct Mat3 {
    pub cols: [Vec3; 3],
}

A 3x3 column-major matrix.

Fields

cols: [Vec3; 3]

Matrix columns.

Implementations

impl Mat3

pub const IDENTITY: Self

Identity matrix.

pub const fn from_cols(x: Vec3, y: Vec3, z: Vec3) -> Self

Creates a matrix from column vectors.

pub fn from_mat4(matrix: Mat4) -> Self

Extracts the upper-left 3x3 matrix from a Mat4.

pub fn get(self, row: usize, col: usize) -> f32

Returns the element at row and column.

pub fn determinant(self) -> f32

Returns the determinant.

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

Returns the inverse matrix, if the matrix is invertible.

pub fn transpose(self) -> Self

Returns the transpose matrix.

pub fn mul_mat3(self, rhs: Self) -> Self

Multiplies this matrix by another matrix.

pub fn mul_vec3(self, rhs: Vec3) -> Vec3

Multiplies this matrix by a vector.

pub fn to_cols_array(self) -> [f32; 9]

Returns the matrix as a column-major array.

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 Index<usize> for Mat3

type Output = Vec3

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl IndexMut<usize> for Mat3

fn index_mut(&mut self, index: usize) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl Mul<Vec3> for Mat3

type Output = Vec3

The resulting type after applying the * operator.

fn mul(self, rhs: Vec3) -> Self::Output

Performs the * operation.

impl Mul for Mat3

type Output = Mat3

The resulting type after applying the * operator.

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

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.
