[name]

A loader for loading an .mtl resource, used internaly by [page:OBJLoader].
The Material Template Library format (MTL) or .MTL File Format is a companion file format to .OBJ that describes surface shading (material) properties of objects within one or more .OBJ files.

Constructor

[name]( [param:LoadingManager loadingManager] )

[page:LoadingManager loadingManager] — LoadingManager to use. Defaults to [page:DefaultLoadingManager DefaultLoadingManager]

Creates a new [name].

Methods

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

[page:String url] — A string containing the path/URL of the .mtl file.
[page:Function onLoad] — (optional) A function to be called after the loading is successfully completed. The function receives the loaded [page:MTLLoaderMaterialCreator MTLLoader.MaterialCreator] instance.
[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.
[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 material.

[method:MTLLoader setPath]( [param:String path] )

[page:String path] — required

Set base path for MTL file.

[method:MTLLoader setResourcePath]( [param:String path] )

[page:String path] — required

Set base path for additional resources like textures. If set, this path will be used as the base path.

[method:MTLLoader setCrossOrigin]( [param:String value] )

[page:String value] — required

If set, assigns the [link:https://developer.mozilla.org/en-US/docs/Web/HTML/CORS_settings_attributes crossOrigin] attribute of the image to the value of *crossOrigin*, prior to starting the load. Default is *"anonymous"*.

[method:MTLLoader setMaterialOptions]( [param:Object options] )

[page:Object options] — required

• side: Which side to apply the material. THREE.FrontSide (default), THREE.BackSide, THREE.DoubleSide
• wrap: What type of wrapping to apply for textures. THREE.RepeatWrapping (default), THREE.ClampToEdgeWrapping, THREE.MirroredRepeatWrapping
• normalizeRGB: RGBs need to be normalized to 0-1 from 0-255. Default: false, assumed to be already normalized
• ignoreZeroRGBs: Ignore values of RGBs (Ka,Kd,Ks) that are all 0's. Default: false
• invertTrProperty: Use values 1 of Tr field for fully opaque. This option is useful for obj exported from 3ds MAX, vcglib or meshlab. Default: false

Set of options on how to construct the materials

[method:MTLLoaderMaterialCreator parse]( [param:String text, param:String path] )

[page:String text] — The textual mtl structure to parse. [page:String path] — The path to the MTL file.

Parse a mtl text structure and return a [page:MTLLoaderMaterialCreator MTLLoader.MaterialCreator] instance.
