Variants

Matrix

4x4 transformation matrix in column-major order.

Fields

matrix: [[f32; 4]; 4]

4x4 matrix.

Decomposed

Decomposed TRS properties.

Fields

translation: [f32; 3]

[x, y, z] vector.

rotation: [f32; 4]

[x, y, z, w] quaternion, where w is the scalar.

scale: [f32; 3]

[x, y, z] vector.

Implementations

impl Transform

pub fn matrix(self) -> [[f32; 4]; 4]

Returns the matrix representation of this transform.

If the transform is Decomposed, then the matrix is generated with the equation matrix = translation * rotation * scale.

pub fn decomposed(self) -> ([f32; 3], [f32; 4], [f32; 3])

Returns a decomposed representation of this transform.

If the transform is Matrix, then the decomposition is extracted from the matrix.

Trait Implementations

impl Clone for Transform

fn clone(&self) -> Transform

Returns a copy 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.
