<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].

<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.
