Type Definition quick_maths::Transform4

type Transform4<T = DefaultFloat> = Transform<T, 4>;

3D transformation, where 4 represents the dimension of the matrix used.

Implementations

impl<T: Float> Transform4<T>

pub fn new(m: Mat4<T>) -> Self

pub fn scale(by: Vec3<T>) -> Self

pub fn rot(axis: Vec3<T>, theta: T) -> Self

pub fn translate(by: Vec3<T>) -> Self

pub fn orthographic(z_near: T, z_far: T) -> Self

pub fn perspective(fov: T, near: T, far: T) -> Self

Perspective transformation

pub fn look_at(pos: Vec3<T>, at: Vec3<T>, up: Vec3<T>) -> Self

A transformation that orients something as if it's looking towards "at" from "pos".

pub fn apply_point(&self, pt: &Vec3<T>) -> Vec3<T>

Applies this transformation as if to a point.

pub fn apply_vec(&self, vec: &Vec3<T>) -> Vec3<T>

Applies this transformation as if applying it to a vector What this means operationally is no transformations.

pub fn apply_normal(&self, n: &Vec3<T>) -> Vec3<T>

Applies this transformation as if applying it to a (surface) normal vector

pub fn apply_ray(&self, r: &Ray3<T>) -> Ray3<T>

Applies this transform to a ray (convenience for applying point to origin and vector to direction)
