Intermediate cloud reveals where the camera encounters visual details, but is not a stable mesh. See how to use it in QA without creating dependency.
Direct answer
ARKit's `rawFeaturePoints` exposes an intermediate point cloud created by scene analysis during world tracking. The points represent notable details in the image and help you investigate why a pose becomes unstable or a virtual object appears to slide. Apple does not guarantee that quantity and distribution will remain the same between frames or system versions; Therefore, this data is suitable for diagnosis and technical visualization, not for a permanent mesh or rigid business rule.
Little visual detail weakens the pose
Smooth walls, reflections, blur, and insufficient light reduce useful signals. The cloud helps make this limitation visible during testing.
Raw point is not confirmed surface
It indicates an observed characteristic, without offering a plan, object or semantics in itself. Don't use the cloud as stable operational geometry.
Comparison must be by behavior
As the points change between frames and releases, evaluate boot time, drift, recovery, and content stability, not cloud equality.
QA needs to reproduce the actual location
Test distances, lighting, movement, materials, and end-use camera routes, recording device and system version.
Nexus Reading
Use feature points as a diagnostic tool to improve the environment, onboarding and positioning; acceptance must continue to be based on observable experience.
FAQ
Are feature points a 3D mesh?
No. They are intermediate results of notable points used by tracking.
Is the quantity stable?
No. Apple does not guarantee stability between frames or system versions.
What are they best for?
To debug tracking conditions, positioning and visual quality in world tracking sessions.
