+        <p>我们不绘制 3D 对象，而是使用图片绘制 2D 平面化的 3D 对象，这通常比绘制 3D 对象要快。</p>
 
+        <p>例如，我们用树木网络制作一个场景，我们让每一棵树的底部是圆柱体，顶部是圆锥体。</p>
 
+        <p>第一步，我们创建圆锥体和圆柱体的Geometry和Material，所有的树都会复用这些。</p>

+          48个多边形组成的树干组成，所以每棵树包含60个多边形。121*60的结果是7260，这并不是很多，当然更精细的3D树可能有1000-3000个多边形构成。如果3000个多边形构成的树，那么121棵树将包含363000个多边形。

+        <p>我们可以在一些绘图应用中手动创建一个Facade，现在让我们编写一些代码来手动生成一个。</p>
 
+        <p>现在写一些代码把对象绘制到纹理中，使用一个 <code class="notranslate" translate="no">RenderTarget</code>，我们提到过使用

+        <p>关于上面代码的一些注意事项：</p>
 
+        <p>我们使用之前代码定义好的视图的 (<code class="notranslate" translate="no">fov</code>) 属性，
 
+        </p>
 
+        <p>我们计算一个包含树的盒模型，这和 <a href="load-obj.html">加载.obj的文件</a> 中提到的方式一致，有一点微小的改变。</p>
 
+        <p>我们再次调用 <code class="notranslate" translate="no">frameArea</code>，稍微改写了一下<a
 
+            href="load-obj.html">加载.obj的文件</a>。
 
+          在这种情况下，我们计算相机需要离物体多远，从而让它的视野以包含对象。然后我们将相机的-z值设置为从对象盒模型的中心到此的距离。</p>
 
+        <p>我们将想要适应的大小乘以1.1倍(<code class="notranslate" translate="no">fudge</code>)
 
+          来确保树完全在渲染目标中。这是因为我们用来计算对象是否适合相机的视口的尺寸，没有考虑到对象的边缘可能会超出我们的可视区域之外。我们可以计算出如何让盒子100%合适，但这会浪费很多空间，所以我们就是蒙混
 
+          <em>(fudge)</em> 一下。
 
+        </p>
 
+        <p>然后我们渲染到RenderTarget中，然后从场景中移除此对象。 </p>
 
+        <p>重点是需要场景中的灯光，但我们需要确保场景中没有其他东西。</p>
 
+        <p>我们也不能给场景设置背景色。</p>
 
+        <pre class="prettyprint showlinemods notranslate lang-js" translate="no">
 
+const scene = new THREE.Scene();
 
+-scene.background = new THREE.Color('lightblue');</pre>
 
+        <p>最后我们返回了纹理，位置和缩放比例，我们需要创建Facade，让它看起来在同一个地方。</p>
 
+        <p>然后我们制作一棵树，调用此代码：</p>
 
+        <pre class="prettyprint showlinemods notranslate lang-js" translate="no">
 
+// 创建Billboard纹理
 
+const tree = makeTree(0, 0);
 
+const facadeSize = 64;
 
+const treeSpriteInfo = makeSpriteTexture(facadeSize, tree);</pre>
 
+        <p>然后我们可以制作一个Facade网络，而不是树网络。</p>
 
+        <pre class="prettyprint showlinemods notranslate lang-js" translate="no">
 
++function makeSprite(spriteInfo, x, z) {
 
++  const {texture, offset, scale} = spriteInfo;
 
++  const mat = new THREE.SpriteMaterial({
 
++    map: texture,
 
++    transparent: true,
 
++  });
 
++  const sprite = new THREE.Sprite(mat);
 
++  scene.add(sprite);
 
++  sprite.position.set(
 
++      offset.x + x,
 
++      offset.y,
 
++      offset.z + z);
 
++  sprite.scale.set(scale, scale, scale);
 
++}
 
+
 
+for (let z = -50; z &lt;= 50; z += 10) {
 
+  for (let x = -50; x &lt;= 50; x += 10) {
 
+-    makeTree(x, z);
 
++    makeSprite(treeSpriteInfo, x, z);
 
+  }
 
+}</pre>
 
+        <p>在上面的代码中，我们应用了定位Facade所需的偏移量和缩放比例，因此他会出现在和原树同一个地方。</p>
 
+        <p>现在我们已经完成了Facade纹理的制作，我们可以再次设置背景。</p>
 
+        <pre class="prettyprint showlinemods notranslate lang-js"
 
+          translate="no">scene.background = new THREE.Color('lightblue');</pre>
 
+        <p>现在我们得到了一个全是树Facades的场景。</p>

+        <p>
 
+          与上面的树模型相比，它们看起来非常相似。我们使用了低分辨率纹理，只有64x64像素，所以Facade是块状的，你当然可以提高分辨率。通常Facade只会用在非常远处的物体，因为当它们非常小的时候，低分辨率纹理就足够了。它节省了绘制远处只有几个像素的精致树模型时间。

+        <p>另一个问题是我们只能从一侧查看树。这往往是通过渲染更多的Facade来解决，比如绘制对象周围的8个方向，然后根据实际相机的方向来设置要展示的Facade。</p>
 
+        <p>是否使用Facade由你决定，如果你决定去使用它们，希望这篇文章给了你一些想法和解决方案。</p>
