Struct Transform 

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

TRS transform: Translation, Rotation, Scale. Transformation order: Scale -> Rotate -> Translate.

Fields

translation: Vec3

rotation: Quat

scale: Vec3

Implementations

impl Transform

pub const IDENTITY: Self

The identity transform (no translation, rotation, or scale).

pub fn from_translation(translation: Vec3) -> Self

Creates a transform with only a translation.

pub fn from_rotation(rotation: Quat) -> Self

Creates a transform with only a rotation.

pub fn from_scale(scale: Vec3) -> Self

Creates a transform with only a scale.

pub fn to_matrix(self) -> Mat4

Convert to a 4x4 matrix (Scale -> Rotate -> Translate).

pub fn transform_point(self, point: Vec3) -> Vec3

Transform a point (applies scale, rotation, and translation).

pub fn transform_vector(self, vector: Vec3) -> Vec3

Transform a direction vector (scale + rotation only, no translation).

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

Compose two transforms.

pub fn inverse(self) -> Self

Compute inverse via matrix decomposition.

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<'de> Deserialize<'de> for Transform

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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 Serialize for Transform

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Transform
