Base class for implementing loaders.
[page:LoadingManager manager] — The [page:LoadingManager loadingManager] for the loader to use. Default is [page:LoadingManager THREE.DefaultLoadingManager].
Creates a new [name].
The crossOrigin string to implement CORS for loading the url from a different domain that allows CORS. Default is `anonymous`.
Whether the XMLHttpRequest uses credentials. See [page:.setWithCredentials]. Default is `false`.
The [page:LoadingManager loadingManager] the loader is using. Default is [page:DefaultLoadingManager].
The base path from which the asset will be loaded. Default is the empty string.
The base path from which additional resources like textures will be loaded. Default is the empty string.
The [link:https://developer.mozilla.org/en-US/docs/Glossary/Request_header request header] used in HTTP request. See [page:.setRequestHeader]. Default is empty object.
This method needs to be implement by all concrete loaders. It holds the logic for loading the asset from the backend.
[page:String url] — A string containing the path/URL of the file to be
loaded.
[page:Function onProgress] (optional) — A function to be called while the
loading is in progress. 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.
This method is equivalent to [page:.load], but returns a [link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise Promise].
[page:Function onLoad] is handled by [link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/resolve Promise.resolve] and [page:Function onError] is handled by [link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/reject Promise.reject].
This method needs to be implement by all concrete loaders. It holds the logic for parsing the asset into three.js entities.
[page:String crossOrigin] — The crossOrigin string to implement CORS for loading the url from a different domain that allows CORS.
Whether the XMLHttpRequest uses credentials such as cookies, authorization
headers or TLS client certificates. See
[link:https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/withCredentials XMLHttpRequest.withCredentials].
Note that this has no effect if you are loading files locally or from the
same domain.
[page:String path] — Set the base path for the asset.
[page:String resourcePath] — Set the base path for dependent resources like textures.
[page:Object requestHeader] - key: The name of the header whose value is
to be set. value: The value to set as the body of the header.
Set the
[link:https://developer.mozilla.org/en-US/docs/Glossary/Request_header request header] used in HTTP request.
