Struct Transform3D 

pub struct Transform3D {
    pub position: Vec3,
    pub rotation: Quat,
    pub scale: Vec3,
}

A 3D transform (position, quaternion rotation, non-uniform scale).

Fields

position: Vec3

rotation: Quat

scale: Vec3

Implementations

impl Transform3D

pub const IDENTITY: Self

Identity transform.

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

Create a new 3D transform.

pub fn to_matrix(&self) -> Mat4

Convert to a 4x4 affine matrix (scale * rotate * translate).

pub fn apply_to_point(&self, point: Vec3) -> Vec3

Apply this transform to a 3D point.

pub fn inverse_matrix(&self) -> Mat4

Compute the inverse 4x4 matrix of this transform.

Use this to undo the transform: t.inverse_matrix() * point4 ≈ original. For non-uniform scale with rotation, the SRT decomposition doesn’t round-trip cleanly, so we provide the inverse as a matrix directly.

Trait Implementations

impl Clone for Transform3D

fn clone(&self) -> Transform3D

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Transform3D

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

Formats the value using the given formatter.

impl Default for Transform3D

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Transform3D

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Transform3D

fn eq(&self, other: &Transform3D) -> 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 Transform3D

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 Transform3D
