<code>
|
|
// 初始化一个加载器
|
|
const loader = new THREE.BufferGeometryLoader();
|
|
|
|
// 加载资源
|
|
loader.load(
|
|
// 资源URL
|
|
'models/json/pressure.json',

|
// onLoad回调
|

|
<p>
|
|
[page:LoadingManager manager] — 加载器所使用的[page:LoadingManager loadingManager]。默认为[page:LoadingManager THREE.DefaultLoadingManager].
|
|
</p>
|
|
<p>
|
|
创建一个新的[name].

|
|
|
<h3>[method:undefined load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )</h3>
|
|
<p>
|
|
[page:String url] — 文件的URL或者路径，也可以为
|
|
[link:https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs Data URI].d<br />
|
|
[page:Function onLoad] — 加载完成时将调用。回调参数为将要加载的[page:BufferGeometry].<br />
|
|
[page:Function onProgress] — 将在加载过程中进行调用。参数为XMLHttpRequest实例，实例包含[page:Integer total]和[page:Integer loaded]字节。<br />
|
|
[page:Function onError] —在加载错误时被调用。<br />
|
|
</p>
|
|
<p>
|
|
从URL中进行加载，并将已经以解析的响应内容传递给onLoad。
|
|
</p>
|
|
|
|
<h3>[method:BufferGeometry parse]( [param:Object json] )</h3>
|
|
<p>
|
|
[page:Object json] — 所需要解析的<em>JSON</em>结构。<br /><br />
|
|
解析一个<em>JSON</em>结构，并返回[page:BufferGeometry].
|
|
