Struct Camera 

pub struct Camera<T = f32> {
    pub position: [T; 3],
    pub up: [T; 3],
    pub right: [T; 3],
    pub forward: [T; 3],
}

Models a camera with position and directions.

Fields

position: [T; 3]

The camera position.

up: [T; 3]

The up direction.

right: [T; 3]

The right direction.

forward: [T; 3]

The forward direction.

Implementations

impl<T> Camera<T>

where T: Float + Copy,

pub fn new(position: [T; 3]) -> Camera<T>

Constructs a new camera.

Places the camera at [x, y, z], looking towards pozitive z.

pub fn orthogonal(&self) -> [[T; 4]; 4]

Computes an orthogonal matrix for the camera.

This matrix can be used to transform coordinates to the screen.

pub fn look_at(&mut self, point: [T; 3])

Orients the camera to look at a point.

pub fn set_yaw_pitch(&mut self, yaw: T, pitch: T)

Sets yaw and pitch angle of camera in radians.

pub fn set_rotation(&mut self, rotation: (T, [T; 3]))

Sets forward, up, and right vectors from a Quaternion rotation relative to the positive z-axis

Trait Implementations

impl<T> Clone for Camera<T>

where T: Clone,

fn clone(&self) -> Camera<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Camera<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> Hash for Camera<T>

where T: Hash,

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T> PartialEq for Camera<T>

where T: PartialEq,

fn eq(&self, other: &Camera<T>) -> 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<T> PartialOrd for Camera<T>

where T: PartialOrd,

fn partial_cmp(&self, other: &Camera<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
