  45. <h2>Constructor</h2>
  46. <h3>[name]( [param:LoadingManager manager] )</h3>
  47. <p>
  48. [page:LoadingManager manager] — The [page:LoadingManager loadingManager] for the loader to use. Default is [page:LoadingManager THREE.DefaultLoadingManager].
  49. </p>
  50. <p>
  51. Creates a new [name].
  52. </p>
  53. <h2>Properties</h2>
  54. <p>See the base [page:Loader] class for common properties.</p>
  55. <h2>Methods</h2>
  56. <p>See the base [page:Loader] class for common methods.</p>
  57. <h3>[method:DataTexture load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )</h3>
  58. <p>
  59. [page:String url] — A string containing the path/URL of the <em>.tga</em> file. <br />
  60. [page:Function onLoad] — (optional) A function to be called after loading is successfully completed. The function receives loaded [page:DataTexture] as an argument.<br />
  61. [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 />
  62. [page:Function onError] — (optional) A function to be called if an error occurs during loading. The function receives the error as an argument.<br />
  63. </p>
  64. <p>
  65. Begin loading from url and pass the loaded [page:DataTexture texture] to onLoad. The [page:DataTexture texture] is also directly returned for immediate use (but may not be fully loaded).
