Struct Mat4 

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

A 4x4 matrix. Data and operations are column-major.

Fields

data: [f32; 16]

Implementations

impl Mat4

pub fn new(data: [f32; 16]) -> Self

pub fn new_perspective_lh( fov_y: f32, aspect_ratio: f32, z_near: f32, z_far: f32, ) -> Self

Creates a left-hand perspective projection matrix with 0-1 depth range. Field of view is in radians. Aspect is width / height. https://docs.rs/glam/latest/src/glam/$f/sse2/mat4.rs.html#818-830

pub fn new_rotation(val: Vec3) -> Self

https://learnopengl.com/Getting-started/Transformations

pub fn new_scaler(scale: f32) -> Self

pub fn new_scaler_partial(scale: Vec3) -> Self

pub fn new_translation(val: Vec3) -> Self

Create a translation matrix. Note that the matrix is 4x4, but it takes len-3 vectors - this is so we can compose it with other 4x4 matrices.

pub const fn new_identity() -> Self

pub fn determinant(&self) -> f32

Calculate the matrix’s determinant.

pub fn transpose(&self) -> Self

Transpose the matrix

pub fn to_cols(&self) -> (Vec4, Vec4, Vec4, Vec4)

Returns cols: x, y, z, w

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

impl Mat4

pub fn to_bytes(&self) -> [u8; 64]
