    説明してない事が1つあり、 WebGLRenderer に physicallyCorrectLights を設定します。 -ライトとの距離は、ライトの落ち方に影響を与えます。 -これは PointLight と SpotLight にのみ影響します。 -RectAreaLight は自動的にこれを行います。

    -

    ライトの場合の基本的な考え方は、フェードアウトする距離を設定しない、intensity を設定しない事です。 -代わりにライトのpowerをルーメン単位で設定すると、three.jsは実際のライトのように物理計算を行います。 -この場合の単位はメートルで、60Wの電球であれば800ルーメン程度の明るさになります。 -またdecayプロパティもあります。 -現実的な減衰のためには 2 に設定します。

    -

    試してみましょう。

    -

    まずは物理的に正しいライトを作ります。

    -
    const renderer = new THREE.WebGLRenderer({antialias: true, canvas});
-+renderer.physicallyCorrectLights = true;
-
    -

    次に power を800ルーメンにし、decay を2にします。 -distance は Infinity にします。

    -
    const color = 0xFFFFFF;
-const intensity = 1;
-const light = new THREE.PointLight(color, intensity);
-light.power = 800;
-light.decay = 2;
-light.distance = Infinity;
-
    -

    GUIを追加して power と decay を変更できるようにします。

    -
    const gui = new GUI();
-gui.addColor(new ColorGUIHelper(light, 'color'), 'value').name('color');
-gui.add(light, 'decay', 0, 4, 0.01);
-gui.add(light, 'power', 0, 2000);
-
    -

    シーンにライトを追加するたびに、Three.jsのレンダリング速度が遅くなる事に注意して下さい。

    次はカメラの扱い方についてです。

    В предыдущей статье рассказывалось, как использовать Geometry. Эта статья о BufferGeometry. BufferGeometry обычно быстрее запускается и использует меньше памяти, но может быть сложнее в настройке. 
    
-
    В статье о Geometry мы рассказали, что для использования Geometry вы предоставляете массив вершин Vector3 (позиций). 
-Затем вы создаете объекты Face3, определяя по индексу 3 вершины, которые составляют каждый треугольник фигуры, которую вы делаете.
-Для каждого Face3 вы можете указать либо нормаль грани, либо нормали для каждой отдельной вершины грани. 
-Вы также можете указать цвет грани или отдельные цвета вершин. Наконец, вы можете создать параллельный массив массивов текстурных координат (UV), 
-один массив для каждой грани, содержащий массив UV, один для каждой вершины грани. 
    
-
    
 
 
    BufferGeometry с другой стороны использует названный BufferAttributes. 
 Каждый атрибут BufferAttribute представляет собой массив данных одного типа: позиции, нормали, цвета и ультрафиолетовые лучи.

    Одна вещь, которую мы не охватили, это то, что есть настройка для WebGLRenderer

-от расстояния до предмета. Это влияет только на PointLight и SpotLight. 
-RectAreaLight делает это автоматически.

    Для источников света, хотя основная идея заключается в том, что вы не устанавливаете 
-расстояние для их затухания и не устанавливаете intensity. Вместо этого вы устанавливаете силу
-power света в люменах, а затем three.js будет использовать физические 
-вычисления, как у настоящих источников света. Единицами three.js в этом случае являются метры, 
-а лампочка мощностью 60 Вт будет иметь около 800 люмен. 
-Там также есть распад decay, он должен быть установлен в 2 для реализма.
    
-
    Давайте проверим это.

    Сначала мы включим физически правильное освещение
    
-
    const renderer = new THREE.WebGLRenderer({antialias: true, canvas});
-+renderer.physicallyCorrectLights = true;

-
    const gui = new GUI();
-gui.addColor(new ColorGUIHelper(light, 'color'), 'value').name('color');

    Важно отметить, что каждый источник света, который вы добавляете в сцену, 
 замедляет скорость рендеринга сцены в three.js, поэтому вы всегда должны 
 стараться использовать как можно меньше для достижения своих целей.

-
    在设置光照时，基本思路是不要设置 distance 来表现光照的衰减，也不要设置 intensity。而是设置光照的 power 属性，以流明为单位，three.js 会进行物理计算，从而表现出接近真实的光照效果。在这种情况下 three.js 参与计算的长度单位是米，一个 60瓦 的灯泡大概是 800 流明强度。并且光源有一个 decay 属性，为了模拟真实效果，应该被设置为 2。
    
-
    下面让我们测试看看。
    
-
    首先开启 physicallyCorrectLights 模式
    
-
    const renderer = new THREE.WebGLRenderer({antialias: true, canvas});
-+renderer.physicallyCorrectLights = true;
-
    
-
    然后我们设置光照的参数，power 设置为 800 流明，decay 设置为 2，distance 设置为 Infinity。
    
-
    const color = 0xFFFFFF;
-const intensity = 1;
-const light = new THREE.PointLight(color, intensity);
-light.power = 800;
-light.decay = 2;

    并且添加 gui 控制 power 和 decay

    需要注意，每添加一个光源到场景中，都会降低 three.js 渲染场景的速度，所以应该尽量使用最少的资源来实现想要的效果。
