Struct cala::prelude::Rotation

pub struct Rotation {
    pub x: f32,
    pub y: f32,
    pub z: f32,
    pub s: f32,
}

Single-precision quaternion.

Fields

x: f32

y: f32

z: f32

s: f32

Implementations

impl Rotation

pub fn identity() -> Rotation

Identity constructor.

pub fn euler(angles: Vector) -> Rotation

Constructor for a rotation defined by a set of Euler angles

The rotation order is Z, then X, then Y. From the point of the object, this is equivalent to a yaw in angles.y, a pitch in angles.x, and a roll in angles.z.

pub fn new(axis: Vector, angle: f32) -> Rotation

Create a new Rotation from axis and angle.

pub fn rotate(&self, vector: Vector) -> Vector

Return the application of the rotation represented by this quaternion to the vector argument.

pub fn then(self, rhs: Rotation) -> Rotation

Add another Rotation after the current Rotation.

Trait Implementations

impl AsRef<[f32; 4]> for Rotation

fn as_ref(&self) -> &[f32; 4]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Rotation

fn clone(&self) -> Rotation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Rotation

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

Formats the value using the given formatter.

impl Default for Rotation

fn default() -> Rotation

Returns the “default value” for a type.

impl Display for Rotation

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

Formats the value using the given formatter.

impl From<[f32; 4]> for Rotation

fn from(q: [f32; 4]) -> Rotation

Converts to this type from the input type.

impl Into<[f32; 4]> for Rotation

fn into(self) -> [f32; 4]

Converts this type into the (usually inferred) input type.

impl Mul<Rotation> for Rotation

type Output = Rotation

The resulting type after applying the * operator.

fn mul(self, rhs: Rotation) -> Rotation

Performs the * operation.

impl Mul<f32> for Rotation

type Output = Rotation

The resulting type after applying the * operator.

fn mul(self, rhs: f32) -> Rotation

Performs the * operation.

impl MulAssign<Rotation> for Rotation

fn mul_assign(&mut self, rhs: Rotation)

Performs the *= operation.

impl PartialEq<Rotation> for Rotation

fn eq(&self, other: &Rotation) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
