| confidenceOut | A list of floats containing all confidence values for the point cloud. |
Retrieves the confidence values for each point in the point cloud.
The point cloud represents positions in the physical environment used by the device for inside-out-tracking. Each point in the point cloud (also known as a "feature point") may have a "confidence" associated with it, indicating how accurate the point is. The value is normalized between 0 and 1.
The list of confidence values is a parallel array to that provided by XRDepthSubsystem.GetPoints.
Existing data is replaced with a list of the current confidence values. To avoid excessive heap allocations, developers may reuse the same list each call. A reallocation only happens when the list's capacity is insufficient.
If confidenceOut is null, this method throws ArgumentNullException.
