How does three.Camera work?

three.Camera is a base class for defining a camera view in a 3D scene by defining its position, orientation, and projection parameters. It provides properties and methods for setting up and manipulating the camera's position, orientation, and view matrix, as well as projection-related parameters such as the field of view, aspect ratio, and near/far clipping planes.

Define a new instance of THREE.CubemapToEquirectangular.
```js
// create renderer, scene, camera, etc.
var renderer = new THREE.WebGLRenderer();
var scene = new THREE.Scene();
var camera = new THREE.Camera( /* ... */ );

// Create a managed CubemapToEquirectangular
var equiManaged = new CubemapToEquirectangular( renderer, true );

import * as THREE from "three";

const camera = new THREE.PerspectiveCamera(
  45,
  window.innerWidth / window.innerHeight,
  1,
  1000
);
camera.position.set(0, 0, 10);

This creates a new PerspectiveCamera object with a field of view of 45 degrees, an aspect ratio equal to the window width divided by the window height, a near clipping plane of 1 unit, and a far clipping plane of 1000 units. The camera is positioned at (0, 0, 10) in 3D space.
