Struct CameraExtrinsics 

pub struct CameraExtrinsics {
    pub position: Vec3,
    pub look_dir: Vec3,
    pub up_dir: Vec3,
}

Camera extrinsics parameters (position and orientation).

Fields

position: Vec3

Camera position in world space.

look_dir: Vec3

Look direction (normalized).

up_dir: Vec3

Up direction (normalized).

Implementations

impl CameraExtrinsics

pub fn new(position: Vec3, look_dir: Vec3, up_dir: Vec3) -> Self

Creates new camera extrinsics from position and directions.

pub fn default_extrinsics() -> Self

Creates extrinsics with camera at origin looking down -Z.

pub fn look_at(position: Vec3, target: Vec3, up: Vec3) -> Self

Creates extrinsics for a camera looking at a target point.

pub fn right_dir(&self) -> Vec3

Gets the right direction (look cross up).

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

Gets the camera frame as (look, up, right).

pub fn view_matrix(&self) -> Mat4

Returns the view matrix (world to camera space).
