Struct FirstPerson 

pub struct FirstPerson {
    pub pos: Point3<World>,
    pub heading: SphericalVec<World>,
}

First-person camera transform.

This is the familiar “FPS” movement mode, based on camera position and heading (look-at vector).

Fields

pos: Point3<World>

Current position of the camera in world space.

heading: SphericalVec<World>

Current heading of the camera in world space.

Implementations

impl FirstPerson

pub fn new() -> Self

Creates a first-person transform with position in the origin and heading in the direction of the positive x-axis.

pub fn look_at(&mut self, pt: Point3<World>)

Rotates the camera to center the view on a world-space point.

pub fn rotate(&mut self, delta_az: Angle, delta_alt: Angle)

Rotates the camera by relative azimuth and altitude.

pub fn rotate_to(&mut self, az: Angle, alt: Angle)

Rotates the camera to an absolute orientation in world space.

pub fn translate(&mut self, delta: Vec3<View>)

Translates the camera by a relative offset in view space.
