Struct EyePose 

pub struct EyePose {
    pub doorways: Arc<[usize]>,
    pub position: Vec3,
    pub forward: Vec3,
    pub down: Vec3,
}

Where an eye stands and which way it looks.

Fields

doorways: Arc<[usize]>

The scene nodes of the doorways the eye walked through from the window’s scene, outermost first: it stands in the space of the last, or in the window scene’s own when there is none.

position: Vec3

Where it stands, in the space it stands in.

forward: Vec3

The direction it looks, of length one.

down: Vec3

The direction that shows as down, square to forward, of length one.

Implementations

impl EyePose

pub fn standing(position: Vec3, yaw: f32, pitch: f32) -> EyePose

An eye in the window scene’s own space at position, turned yaw radians to the right of the space’s z and pitch up from level.

pub fn camera(&self, focal_length: f32) -> Camera

The camera the eye sees through, with focal_length, in the space it stands in.

pub fn pitch(&self) -> f32

How far the eye looks up from level, in radians.

pub fn turn(&mut self, yaw: f32, pitch: f32)

Turns the eye yaw radians to the right about its space’s down, then pitch up, no further than PITCH_LIMIT from level.

pub fn walking_axes(&self) -> (Vec3, Vec3)

The level directions the eye walks along: ahead, as it looks but level with its space’s floor, and to its right.
