Struct Transform 

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

A transformation represented as separate components.

This is useful for UI display and incremental manipulation.

Fields

translation: Vec3

Translation component.

rotation: Quat

Rotation component as a quaternion.

scale: Vec3

Scale component.

Implementations

impl Transform

pub fn identity() -> Self

Creates a new identity transform.

pub fn from_translation(translation: Vec3) -> Self

Creates a transform from a translation.

pub fn from_rotation(rotation: Quat) -> Self

Creates a transform from a rotation.

pub fn from_scale(scale: Vec3) -> Self

Creates a transform from a scale.

pub fn from_matrix(matrix: Mat4) -> Self

Creates a transform from a Mat4.

This decomposition may not be exact for matrices with shear.

pub fn to_matrix(&self) -> Mat4

Converts this transform to a Mat4.

pub fn euler_angles(&self) -> Vec3

Returns the rotation as Euler angles (in radians).

pub fn set_euler_angles(&mut self, angles: Vec3)

Sets the rotation from Euler angles (in radians).

pub fn euler_angles_degrees(&self) -> Vec3

Returns the rotation as Euler angles (in degrees).

pub fn set_euler_angles_degrees(&mut self, degrees: Vec3)

Sets the rotation from Euler angles (in degrees).

pub fn translate(&mut self, delta: Vec3)

Translates the transform.

pub fn rotate(&mut self, delta: Quat)

Rotates the transform.

pub fn scale_by(&mut self, factor: Vec3)

Scales the transform.

pub fn snap_translation(&mut self, snap: f32)

Applies snap to translation.

pub fn snap_rotation(&mut self, snap_degrees: f32)

Applies snap to rotation (in degrees).

pub fn snap_scale(&mut self, snap: f32)

Applies snap to scale.
