Inspector

选框为应用开启空间锚点能力。

然后你可以调用空间锚点相关接口在应用内实现空间锚点功能。

新建一个空物体名为SpatialAnchor添加SpatialAnchor组件指定地方放置物体、SeethroughManager代码开启透视

编写代码SpatialAnchor

查询所有空间锚点//SetLogInfo(LoadSpatialAnchorAsync:

记录日志if

如果锚点列表中不存在该锚点{i;PXR_MixedReality.LocateAnchor(key,

获取锚点组件anchor.SetAnchorHandle(key);

设置锚点句柄//
