+<p><a href="/en-US/docs/Web/API/WebGL_API">WebGL API</a> 的 <strong><code>WebGLRenderingContext.cullFace()</code></strong> 指定正面和/或背面多边形是否可以剔除。</p>

+
+<dl>
+ <dt><code>mode</code></dt>
+ <dd>{{domxref("GLenum")}} 指定适合进行剔除的面是正面还是背面。默认值是 <code>gl.BACK</code>. 可能的值有:
+ <ul>
+  <li><code>gl.FRONT</code></li>
+  <li><code>gl.BACK</code></li>
+  <li><code>gl.FRONT_AND_BACK</code></li>

+
+<p>多边形剔除功能默认不开启。 想要开启这个功能, 使用{{domxref("WebGLRenderingContext.enable", "enable()")}} 和 {{domxref("WebGLRenderingContext.disable", "disable()")}} 方法，传入参数<code>gl.CULL_FACE</code>.</p>
+
+<pre class="brush: js notranslate">gl.enable(gl.CULL_FACE);
+gl.cullFace(gl.FRONT_AND_BACK);
+</pre>
+
+<p>需要 <code>CULL_FACE_MODE</code> 常量来检查当前多边形剔除模式。</p>
+
+<pre class="brush: js notranslate">gl.getParameter(gl.CULL_FACE_MODE) === gl.FRONT_AND_BACK;
+// true
