Task 4: Confirm floor-mode hall POI visibility — Implementation Report

Status

DONE

Summary

Source inspection confirms floor mode already prevents hall POI hiding via distance/limit pruning. No code change required.

Findings

Step 1: Floor visibility tier inspection

Confirmed getPoiVisibilityTier() at src/components/map/ThreeMap.vue:650-651:

const getPoiVisibilityTier = (): PoiVisibilityTier => {
  if (activeView.value === 'floor') return 'full'

Step 2: Visibility tier behavior analysis

When tier is 'full':

• getPoiVisibilityLimit('full') returns Number.POSITIVE_INFINITY.
• getPoiScreenSpacing('full') returns 0.

Step 3: Pruning mechanism verification

In updatePoiVisibilityByDistance():

• exceedsLimit is false for Infinity because Number.isFinite(Infinity) is false.
• isTooClose is false when spacing is 0.
• exhibition_hall and exhibition_hall_entrance are in corePoiCategories.

Conclusion

Floor mode POI visibility is already correctly configured:

1. Distance pruning is disabled.
2. Count pruning is disabled.
3. Hall POIs pass category checks.
4. Selected/focused POIs always show.

No code modification needed.

Files Inspected

• src/components/map/ThreeMap.vue

Commands Run

None required — source inspection confirms correct behavior.

Commits Created

None — no code changes.

Self-Review

• Floor mode already returns 'full' visibility tier.
• 'full' tier prevents both distance and count pruning.
• Hall POIs are included in corePoiCategories.
• Logic is correct and no defensive guard is needed.

Concerns

None.
