Struct OrbitalCamera 

pub struct OrbitalCamera {
    pub target: Vec3,
    pub azimuth: f32,
    pub elevation: f32,
    pub distance: f32,
    pub dist_min: f32,
    pub dist_max: f32,
    pub elev_min: f32,
    pub elev_max: f32,
    /* private fields */
}

Orbital camera — rotates around a target point at a configurable distance.

Controls:

• azimuth : horizontal rotation angle (radians)
• elevation : vertical angle (radians, clamped to avoid gimbal flip)
• distance : how far from the target

Fields

target: Vec3

azimuth: f32

elevation: f32

distance: f32

dist_min: f32

Min/max distance clamp.

dist_max: f32

elev_min: f32

Min/max elevation clamp.

elev_max: f32

Implementations

impl OrbitalCamera

pub fn new(target: Vec3, distance: f32) -> Self

pub fn set_target(&mut self, pos: Vec3)

Set a new target (spring-animated follow).

pub fn rotate(&mut self, delta_azimuth: f32, delta_elevation: f32)

Rotate by delta angles (e.g. from mouse drag).

pub fn zoom(&mut self, delta: f32)

Zoom by changing the target distance.

pub fn tick(&mut self, dt: f32) -> (Vec3, Vec3)

Tick by dt. Returns the camera eye position (for look_at).

pub fn view_matrix(&mut self, dt: f32) -> Mat4

Compute view matrix from orbital parameters.

Trait Implementations

impl Clone for OrbitalCamera

fn clone(&self) -> OrbitalCamera
