Loader

CompressedTextureLoader

Abstract base class for loading compressed texture formats S3TC, ASTC or ETC. Textures are internally loaded via FileLoader.

Derived classes have to implement the parse() method which holds the parsing for the respective format.

Constructor

new CompressedTextureLoader( manager : LoadingManager ) (abstract)

Constructs a new compressed texture loader.

manager

The loading manager.

Methods

.load( url : string, onLoad : function, onProgress : onProgressCallback, onError : onErrorCallback ) : CompressedTexture

Starts loading from the given URL and passes the loaded compressed texture to the onLoad() callback. The method also returns a new texture object which can directly be used for material creation. If you do it this way, the texture may pop up in your scene once the respective loading process is finished.

url

The path/URL of the file to be loaded. This can also be a data URI.

onLoad

Executed when the loading process has been finished.

onProgress

Executed while the loading is in progress.

onError

Executed when errors occur.

Overrides: Loader#load
Returns: The compressed texture.
