A loader for loading a [page:BufferGeometry].
|

|
|
This uses the [page:FileLoader] internally for loading files.

<h2>Code Example</h2>
|
||
|
|
|
||
|
|
<code>
|
||
|
|
// instantiate a loader
|
||
|
|
const loader = new THREE.BufferGeometryLoader();
|
||
|
|
|
||
|
|
// load a resource
|
||
|
|
loader.load(
|
||
|
|
// resource URL
|
||
|
|
'models/json/pressure.json',
|
||
|
|
|
||
|
|
// onLoad callback
|
||
|
|
function ( geometry ) {
|
||
|
|
const material = new THREE.MeshLambertMaterial( { color: 0xF5F5F5 } );
|
||
|
|
const object = new THREE.Mesh( geometry, material );
|
||
|
|
scene.add( object );
|
||
|
|
},
|
||
|
|
|
||
|
|
// onProgress callback
|
||
|
|
function ( xhr ) {
|
||
|
|
console.log( (xhr.loaded / xhr.total * 100) + '% loaded' );
|
||
|
|
},
|
||
|
|
|
||
|
|
// onError callback
|
||
|
|
function ( err ) {
|
||
|
|
console.log( 'An error happened' );

|
|
||
|
|
<h3>[name]( [param:LoadingManager manager] )</h3>
|
||
|
|
<p>
|
||
|
|
[page:LoadingManager manager] — The [page:LoadingManager loadingManager] for the loader to use. Default is [page:LoadingManager THREE.DefaultLoadingManager].
|
||
|
|
</p>
|
||
|
|
<p>
|

<h2>Methods</h2>
|
||
|
|
<p>See the base [page:Loader] class for common methods.</p>
|
||
|
|
|
||
|
|
<h3>[method:undefined load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )</h3>
|
||
|
|
<p>
|
||
|
|
[page:String url] — the path or URL to the file. This can also be a
|
||
|
|
[link:https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs Data URI].d<br />
|
||
|
|
[page:Function onLoad] — Will be called when load completes. The argument will be the loaded [page:BufferGeometry].<br />
|
||
|
|
[page:Function onProgress] (optional) — Will be called while load progresses. The argument will be the ProgressEvent instance, which contains .[page:Boolean lengthComputable], .[page:Integer total] and .[page:Integer loaded]. If the server does not set the Content-Length header; .[page:Integer total] will be 0.<br />
|
||
|
|
[page:Function onError] (optional) — Will be called when load errors.<br />
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
Begin loading from url and call onLoad with the parsed response content.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[method:BufferGeometry parse]( [param:Object json] )</h3>
|
||
|
|
<p>
|
||
|
|
[page:Object json] — The `JSON` structure to parse.<br /><br />
|
||
|
|
Parse a `JSON` structure and return a [page:BufferGeometry].
