SurfaceObserver 是 Unity 中适用于空间映射功能的主 API 门户。
用户应创建一个 SurfaceObserver，调用 Update 以生成 SurfaceChanged 事件，并针对所需的那些表面调用 GetMeshAsync，完成此对象后，调用 Dispose。
| SurfaceObserver | SurfaceObserver 的基本构造函数。 |
| Dispose | 不再需要 SurfaceObserver 时，调用 Dispose。这将确保对此对象进行相应的清除，但不影响 RequestMeshAsync 返回的任何网格、组件或对象。 |
| SurfaceChangedDelegate | SurfaceChangedDelegate 用于处理在 SurfaceObserver 上调用 Update 时生成的 SurfaceChanged 事件。应用程序可使用 bounds、changeType 和 updateTime 针对一组已知表面选择性地生成网格数据。 |
| SurfaceDataReadyDelegate | SurfaceDataReadyDelegate 用于处理引擎完全生成网格时生成的事件。系统通过 GetMeshAsync 请求网格生成事件，并可能需要许多帧才能完全生成网格。 |
