Struct FpsCameraController 

pub struct FpsCameraController {
    pub position: Point3<f32>,
    pub yaw: f32,
    pub pitch: f32,
    pub move_speed: f32,
    pub min_pitch: f32,
    pub max_pitch: f32,
}

First-person fly / walk camera controller.

Translates along view-aligned axes and rotates with yaw and pitch.

Fields

position: Point3<f32>

World-space position of the camera eye.

yaw: f32

Horizontal heading angle in radians.

pitch: f32

Vertical look angle in radians.

move_speed: f32

Movement speed units per second.

min_pitch: f32

Minimum pitch angle in radians (default: ~ -89°).

max_pitch: f32

Maximum pitch angle in radians (default: ~ +89°).

Implementations

impl FpsCameraController

pub fn new(position: Point3<f32>) -> Self

Create a new first-person camera controller at position.

pub fn rotate(&mut self, delta_yaw: f32, delta_pitch: f32)

Rotate view by delta yaw and pitch (in radians).

pub fn horizontal_forward(&self) -> Vector3<f32>

Forward direction vector on the horizontal plane (unit length).

pub fn horizontal_right(&self) -> Vector3<f32>

Right direction vector on the horizontal plane (unit length).

pub fn look_direction(&self) -> Vector3<f32>

True look direction vector including pitch.

pub fn move_relative( &mut self, forward: f32, strafe: f32, vertical: f32, dt: f32, )

Move the camera relative to its current heading.

forward: +1 = forward, -1 = backward strafe: +1 = right, -1 = left vertical: +1 = up, -1 = down

pub fn update_camera(&self, camera: &mut Camera)

Synchronize state to an engine Camera.
