+ *\r
+ * Scene is a class for containing scene elements loaded from scene format file(e.g., glTF). Scene elements mean scene graph, cameras, and animations.\r
+ *\r
+ * Basic idea:-\r
+ *\r
+ * 1) The Scene is initialized with diffuse and specular cube map for the Image Based Lighting.\n\r
+ * If the Scene initialized without cube map, the objects of the Scene cannot be rendered with IBL.\n\r
+ * 2) The Scene is loaded from each scene format file(e.g., glTF).\n\r
+ * 3) The Scene can have a point light or a directional light.(optional)\n\r
+ * 4) The Scene playes each actor's animation.\n\r
+ *\r
+ *\r
+ * Usage example: -\r
+ *\r
+ * @code\r
+ *\r
+ * void SceneExample::Create( Application& application )\r
+ * {\r
+ * // Use 'Scene::New( URL_SCENE_FILE )', if you don't want to render with IBL.\r
+ * Scene scene = Scene::New( URL_SCENE_FILE, URL_DIFFUSE_TEXTURE, URL_SPECULAR_TEXTURE );\r
+ *\r
+ * Stage::GetCurrent().Add( scene );\r
+ * scene.PlayAnimations();\r
+ *\r
+ * scene.SetLight( Scene::LightType::DIRECTIONAL_LIGHT, Vector3( 1.0, 1.0, -1.0 ), Vector3( 0.3, 0.3, 0.3 ) );\r
+ * }\r
+ *\r
+ * @endcode\r
+ *\r
+ * @remarks This control makes 3D Layer internally. Therefore, if any 2D UI\r
+ * control is added as a child of this Scene, the functionality of the 2D UI\r
+ * may not work well.\r
