protected void OnBeginSurfaceEviction (bool shouldBeActiveWhileRemoved, XR.WSA.SpatialMappingBase.Surface surface);

説明

This method is called when the system notifies the spatial mapping component that a surface has been removed.

The system will notify the spatial mapping component when a surface has been removed from the physical environment. The component must determine what to do with the corresponding surface GameObject. Classes that derived from SpatialMappingBase must implement this method.
