Struct Camera 

pub struct Camera {
    pub position: Vec3,
    pub yaw: f32,
    pub pitch: f32,
    pub aspect: f32,
    pub fov: f32,
    pub znear: f32,
    pub zfar: f32,
}

Fields

position: Vec3

yaw: f32

Radians, rotation around world +Y.

pitch: f32

Radians. Callers should keep this in roughly (-PI/2, PI/2) to avoid the view flipping through the poles — up is fixed to world +Y, so there’s no roll to fall back on there.

aspect: f32

fov: f32

Vertical field of view, in degrees.

znear: f32

zfar: f32

Implementations

impl Camera

pub fn forward(&self) -> Vec3

pub fn yaw_pitch_from_forward(forward: Vec3) -> (f32, f32)

Extracts yaw/pitch (no roll) from a normalized direction vector — the inverse of forward(). Shared by look_at and by CameraComponent::derive_camera, which both need to turn a direction into this camera’s angle representation.

pub fn look_at(&mut self, target: Vec3)

Points the camera at target from its current position, for call sites that think in terms of “look at this point” rather than angles.

pub fn build_view_projection_matrix(&self) -> Mat4

Trait Implementations

impl Clone for Camera

fn clone(&self) -> Camera

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Camera
