Fields

position: [f64; 3]

Camera position in world space.

target: [f64; 3]

Look-at target point.

up: [f64; 3]

Up vector (usually [0, 1, 0]).

fov_deg: f64

Vertical field of view in degrees.

near: f64

Near clipping plane distance.

far: f64

Far clipping plane distance.

aspect: f64

Viewport aspect ratio (width / height).

Implementations

impl PyCamera

pub fn new(position: [f64; 3], target: [f64; 3]) -> Self

Create a default perspective camera.

pub fn default_perspective() -> Self

Default camera looking down the negative Z axis.

pub fn orbit(&mut self, delta_yaw: f64, delta_pitch: f64)

Orbit the camera around the target by delta_yaw and delta_pitch (radians).

pub fn pan(&mut self, offset: [f64; 3])

Pan the camera by a world-space offset.

pub fn zoom(&mut self, factor: f64)

Zoom by moving the camera closer to (factor < 1) or farther from (factor > 1) the target.

pub fn look_at(&mut self, target: [f64; 3])

Point the camera directly at a given world position.

pub fn view_direction(&self) -> [f64; 3]

Compute the view direction (normalized).

pub fn distance_to_target(&self) -> f64

Distance from camera to target.
