Struct Mat4 

pub struct Mat4 {
    pub data: [f32; 16],
}

4x4 transformation matrix (column-major, like OpenGL/WebGL)

Fields

data: [f32; 16]

Matrix data in column-major order

Implementations

impl Mat4

pub const IDENTITY: Self

Identity matrix

pub fn identity() -> Self

Create identity matrix

pub fn from_translation(v: Vec3) -> Self

Create translation matrix

pub fn from_scale(v: Vec3) -> Self

Create scale matrix

pub fn from_rotation(q: Quat) -> Self

Create rotation matrix from quaternion

pub fn from_rotation_translation_scale( rotation: Quat, translation: Vec3, scale: Vec3, ) -> Self

Create transformation matrix from rotation, translation, and scale

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

Multiply two matrices (self * other)

pub fn transform_point(&self, p: Vec3) -> Vec3

Transform a point by this matrix

pub fn transform_normal(&self, n: Vec3) -> Vec3

Transform a normal (direction) by this matrix (ignores translation)

pub fn as_array(&self) -> &[f32; 16]

Get matrix as flat array for GPU upload

pub fn as_4x3(&self) -> [f32; 12]

Get matrix as 4x3 for GPU upload (strips last row, common for skinning)

Trait Implementations

impl Clone for Mat4

fn clone(&self) -> Mat4

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mat4

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

Formats the value using the given formatter.

impl Default for Mat4

fn default() -> Self

Returns the “default value” for a type.

impl Mul for Mat4

type Output = Mat4

The resulting type after applying the * operator.

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

Performs the * operation.

impl PartialEq for Mat4

fn eq(&self, other: &Mat4) -> 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.
