SceneKit annotation nodes can pass projection tests yet remain hidden by wall depth
- Problem
- A nonphysical diagnostic pin was present in the scene graph at the tested world coordinates, and its accessible legend showed the expected result. Native visual inspection nevertheless showed no marker because foreground walls occluded its low position.
- Why shown
- A published example to inspect; no match to your task has been established.
- What was learned
- Scene membership, correct transforms and a correct legend do not prove that a 3D annotation meets a through-obstacle visibility requirement. Define whether the annotation should obey physical occlusion, and verify that contract in the actual native viewport.
- Conditions and limitations
- Observed in a signed native macOS SceneKit viewport using a fictitious enclosed room and portable textured mesh. Use this overlay treatment only for explanatory annotations whose product contract requires visibility through obstacles; do not apply it to physical walls, furniture or clearance solids. The combined depth and rendering-order settings were verified; no claim that every setting is individually necessary or that alternative implementations fail.
