<h2>使用示例</h2>
<h3>1.开启环境贴图</h3>
<pre><code class="language-javascript">var mIBLManagerConfig = new BCore.Extension.IBLManagerConfig(viewer3D);
var mIBLManager = new BCore.Extension.IBLManager(mIBLManagerConfig);
mIBLManager.openIBL();</code></pre>
<h3>2.关闭环境贴图</h3>
<pre><code class="language-javascript">var mIBLManagerConfig = new BCore.Extension.IBLManagerConfig(viewer3D);
var mIBLManager = new BCore.Extension.IBLManager(mIBLManagerConfig);
mIBLManager.openIBL();
mIBLManager.closeIBL();</code></pre>
<h3>3.设置环境贴图图片</h3>
<pre><code class="language-javascript">var mIBLManagerConfig = new BCore.Extension.IBLManagerConfig(viewer3D);
var mIBLManager = new BCore.Extension.IBLManager(mIBLManagerConfig);
mIBLManager.openIBL();
//使用时替换成您所访问的域名地址
const domain = &#039;https://ib.bimernet.com&#039;
mIBLManager.setIBLImages([
`${domain}/static/assets/bimengine/3d/textures/cube/pisa/nx.png`,
`${domain}/static/assets/bimengine/3d/textures/cube/pisa/ny.png`,
`${domain}/static/assets/bimengine/3d/textures/cube/pisa/nz.png`,
`${domain}/static/assets/bimengine/3d/textures/cube/pisa/px.png`,
`${domain}/static/assets/bimengine/3d/textures/cube/pisa/py.png`,
`${domain}/static/assets/bimengine/3d/textures/cube/pisa/pz.png`,
]).then(() =&gt; {
mIBLManager.updateIBL();
});</code></pre>
<h3>4.获取环境贴图强度</h3>
<pre><code class="language-javascript">var mIBLManagerConfig = new BCore.Extension.IBLManagerConfig(viewer3D);
var mIBLManager = new BCore.Extension.IBLManager(mIBLManagerConfig);
mIBLManager.openIBL();
let envMapIntensity = mIBLManager.getEnvMapIntensity();</code></pre>
<h3>设置环境贴图强度</h3>
<pre><code class="language-javascript">var mIBLManagerConfig = new BCore.Extension.IBLManagerConfig(viewer3D);
var mIBLManager = new BCore.Extension.IBLManager(mIBLManagerConfig);
mIBLManager.openIBL();
mIBLManager.setEnvMapIntensity(4);</code></pre>
