Hello Greg, Yes, I’m referring to ARFrame's raycastQuery. Essentially, I’d like to measure human facial features using the rear camera with LiDAR, and take advantage of any temporal refinement available in either ARKit or AVFoundation. Is depth data refined over time during an ARKit session? I’d really appreciate any recommendations—especially from a DTS engineer.

Does it make sense to raycast face landmarks in the first place? Assuming face is stationary long enough?
