Surface Observer. Get Observed Surfaces Method
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Gets metadata for the set of surfaces observed within the bounding volume at the moment.
public: virtual IMapView<Platform::Guid, SpatialSurfaceInfo ^> ^ GetObservedSurfaces() = GetObservedSurfaces;
IMapView<winrt::guid, SpatialSurfaceInfo const&> GetObservedSurfaces();
public IReadOnlyDictionary<Guid,SpatialSurfaceInfo> GetObservedSurfaces();
Public Function GetObservedSurfaces () As IReadOnlyDictionary(Of Guid, SpatialSurfaceInfo)
The observed surfaces within the bounding volume. If no bounding volume has been set, no surfaces will be returned.
Each SpatialSurfaceInfo snapshot is immutable, so you can compare their values later to see if a given surface has recently experienced a mesh update.
- If you see a SpatialSurfaceInfo with an Id you haven't seen before, treat it as new mesh.
- If you see a SpatialSurfaceInfo with a known Id, but with a new UpdateTime, treat it as updated mesh.
- If you no longer see a SpatialSurfaceInfo with a known Id, treat it as removed mesh.
