## Properties

See the base [page:Loader] class for common properties.

## Methods

See the base [page:Loader] class for common methods.

### [method:undefined load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )

[page:String url] — A string containing the path/URL of the `.3dl` file.
[page:Function onLoad] — (optional) A function to be called after the loading is successfully completed. The function receives the result of the [page:Function parse] method.
[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. If the server does not set the Content-Length header; .[page:Integer total] will be 0.
[page:Function onError] — (optional) A function to be called if an error occurs during loading. The function receives the error as an argument.

Begin loading from url and return the loaded LUT.

### [method:Object parse]( [param:String input] )

[page:String input] — The 3dl data string.

Parse a 3dl data string and fire [page:Function onLoad] callback when complete. The argument to [page:Function onLoad] will be an [page:Object object] containing the following LUT data: [page:Number .size], [page:DataTexture .texture] and [page:Data3DTexture .texture3D].

### [method:this setType]( [param:Number type] )

[page:Number type] - The texture type. See the [page:Textures texture constants] page for details.

Sets the desired texture type. Only [page:Textures THREE.UnsignedByteType] and [page:Textures THREE.FloatType] are supported. The default is [page:Textures THREE.UnsignedByteType].
