<h1>[name]</h1>
<p class="desc">A loader for loading a <em>.svg</em> resource.<br >
<a href="https://en.wikipedia.org/wiki/Scalable_Vector_Graphics">Scalable Vector Graphics</a> is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation.

<h2>代码示例</h2>
<code>
// instantiate a loader
const loader = new SVGLoader();
// load a SVG resource
loader.load(
// resource URL
'data/svgSample.svg',
// called when the resource is loaded
function ( data ) {
const paths = data.paths;
const group = new THREE.Group();
for ( let i = 0; i < paths.length; i ++ ) {
const path = paths[ i ];
const material = new THREE.MeshBasicMaterial( {
color: path.color,
side: THREE.DoubleSide,
depthWrite: false
} );
const shapes = SVGLoader.createShapes( path );
for ( let j = 0; j < shapes.length; j ++ ) {
const shape = shapes[ j ];
const geometry = new THREE.ShapeGeometry( shape );
const mesh = new THREE.Mesh( geometry, material );
group.add( mesh );
}
}
scene.add( group );
},
// called when loading is in progresses
function ( xhr ) {
console.log( ( xhr.loaded / xhr.total * 100 ) + '% loaded' );

// called when loading has errors
function ( error ) {

<h2>Constructor</h2>
<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>
Creates a new [name].
</p>
<h2>Properties</h2>
<p>See the base [page:Loader] class for common properties.</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] — A string containing the path/URL of the <em>.svg</em> file.<br />
[page:Function onLoad] — (optional) A function to be called after loading is successfully completed. The function receives an array of [page:ShapePath] as an argument.<br />
[page:Function onProgress] — (optional) A function to be called while the loading is in progress. The argument will be the XMLHttpRequest instance, which contains [page:Integer total] and [page:Integer loaded] bytes.<br />
[page:Function onError] — (optional) A function to be called if an error occurs during loading. The function receives the error as an argument.<br />
</p>
<p>
Begin loading from url and call onLoad with the response content.
</p>
<h2>Static Methods</h2>
<h3>[method:Array createShapes]( [param:ShapePath shape] )</h3>
<p>
[page:ShapePath shape] — A ShapePath from the array of [page:ShapePath], given as argument in the onLoad function for the load function of [page:SVGLoader].<br />
</p>
<p>
Returns one or more [page:Shape] objects created from the [param:ShapePath shape] provided as an argument in this function.
