A Unity package is either "Preview" or "Verified". The latest version of ARFoundation is usually marked as preview and may include experimental or unstable features. A "verified" package is developed targeting a specific version of Unity (though it may work with earlier version as well). All packages verified for the same version of Unity are known to work well together.
## AllPointCloudPoints
This sample shows all feature points over time, not just the current frame's feature points as the "AR Default Point Cloud" prefab does. It does this by using a slightly modified version of the `ARPointCloudParticleVisualzier` component that stores all the feature points in a Dictionary. Since each feature point has a unique identifier, it can look up the stored point and update its position in the dictionary if it already exists. This can be a useful starting point for custom solutions that require the entire map of point cloud points, e.g., for custom mesh reconstruction techniques.

## CameraGrain
This sample demonstrates the camera grain effect. Once a plane is deteced, you can place a cube on it with a material that simulates the camera grain noise in the camera feed. See the `CameraGrain.cs` script.
This sample requires iOS 13 and is not supported on Android. It also is only supported on Unity 2020.2 and above.
