Struct Mat4 

pub struct Mat4(pub [f32; 16]);

A 4×4 matrix, column-major: m[col * 4 + row].

Tuple Fields

0: [f32; 16]

Implementations

impl Mat4

pub const IDENTITY: Mat4

pub fn translation(v: Vec3) -> Mat4

pub fn scaling(v: Vec3) -> Mat4

pub fn rotation_x(a: f32) -> Mat4

Turned a radians about x (right-handed, as Axis.XP).

pub fn rotation_y(a: f32) -> Mat4

pub fn rotation_z(a: f32) -> Mat4

pub fn rotation_zyx(r: Vec3) -> Mat4

ModelPart’s turn: JOML rotationZYX(z, y, x) — z, then y, then x applied to the vector last.

pub fn part(pivot: Vec3, rotation: Vec3, scale: Vec3) -> Mat4

ModelPart.translateAndRotate: to the pivot, turned, scaled.

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

pub fn transform_dir(&self, d: Vec3) -> Vec3

A direction: turned and scaled, not moved.

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

A normal, kept a unit vector (good for rotations and uniform scales, which is what bodies use).
