Struct Transform 

pub struct Transform {
    pub translation: Vec3,
    pub rotation: Quat,
    pub scale: Vec3,
}

A translation, rotation, and scale transform.

Fields

translation: Vec3

Local translation.

rotation: Quat

Local rotation.

scale: Vec3

Local scale.

Implementations

impl Transform

pub const IDENTITY: Self

Identity transform.

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

Creates a transform from translation, rotation, and scale.

pub const fn from_translation(value: Vec3) -> Self

Creates a translation transform.

pub const fn from_rotation(value: Quat) -> Self

Creates a rotation transform.

pub const fn from_scale(value: Vec3) -> Self

Creates a scale transform.

pub fn looking_at(eye: Vec3, target: Vec3, up: Vec3) -> Self

Creates a transform that looks from eye toward target.

pub fn to_mat4(self) -> Mat4

Converts the transform to a column-major matrix.

pub fn from_mat4(matrix: Mat4) -> Option<Self>

Creates a transform from a TRS matrix.

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

Composes two transforms.

pub fn inverse(self) -> Self

Returns the inverse transform.

pub fn forward(self) -> Vec3

Returns the transformed forward direction (-Z).

pub fn right(self) -> Vec3

Returns the transformed right direction (+X).

pub fn up(self) -> Vec3

Returns the transformed up direction (+Y).

pub fn translate_by(self, delta: Vec3) -> Self

Returns this transform translated by delta.

pub fn rotate_by(self, rotation: Quat) -> Self

Returns this transform rotated by rotation.

pub fn scale_by(self, scale: Vec3) -> Self

Returns this transform scaled component-wise by scale.

Trait Implementations

impl Clone for Transform

fn clone(&self) -> Transform

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Transform

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

Formats the value using the given formatter.

impl Default for Transform

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Transform

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

impl Copy for Transform
