class in UnityEngine.Experimental.XR
/
继承自：Experimental.IntegratedSubsystem
切换到手册允许外部系统为 Unity 提供动态网格。
XRMeshSubsystem 使外部系统能够为 Unity 提供动态网格。为了在执行期间不阻塞主线程，网格在后台线程上处理（包括物理烘焙）。这对于在运行时期间提供动态网格非常有用，例如空间感知 AR 设备。
| GenerateMeshAsync | 请求生成具有 TrackableId meshId 的网格。生成完成时调用 /onMeshGenerationComplete/。 |
| TryGetMeshInfos | 获取系统跟踪的每个网格的相关信息。 |
