Struct Quaternion 

pub struct Quaternion { /* private fields */ }

Rotation quaternion.

Represents a 3D rotation using quaternion representation (i, j, k, w). Quaternions provide smooth interpolation and avoid gimbal lock.

Fields

• i, j, k: Imaginary components
• w: Real (scalar) component

Quaternion Format

Standard quaternion format: q = w + xi + yj + zk

Example

use rpfm_lib::files::bmd::common::Quaternion;

let mut quat = Quaternion::default();
quat.set_w(1.0);  // Identity rotation

Implementations

impl Quaternion

pub fn i(&self) -> &f32

Imaginary i component.

pub fn j(&self) -> &f32

Imaginary j component.

pub fn k(&self) -> &f32

pub fn w(&self) -> &f32

Real (scalar) w component.

impl Quaternion

pub fn i_mut(&mut self) -> &mut f32

pub fn j_mut(&mut self) -> &mut f32

Imaginary j component.

pub fn k_mut(&mut self) -> &mut f32

Imaginary k component.

pub fn w_mut(&mut self) -> &mut f32

Trait Implementations

impl Clone for Quaternion

fn clone(&self) -> Quaternion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Quaternion

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

Formats the value using the given formatter.

impl Decodeable for Quaternion

fn decode<R: ReadBytes>( data: &mut R, _extra_data: &Option<DecodeableExtraData<'_>>, ) -> Result<Self>

Decodes binary data into the implementing type.

impl Default for Quaternion

fn default() -> Quaternion

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Quaternion

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encodeable for Quaternion

fn encode<W: WriteBytes>( &mut self, buffer: &mut W, _extra_data: &Option<EncodeableExtraData<'_>>, ) -> Result<()>

Encodes the implementing type into binary data.

impl PartialEq for Quaternion

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
