  4. TRACKING ▸ ARWorldTrackingConfiguration ▸ ARAnchors fix position in real world

    ⚓ ▸ Don’t use feature points to place content ▸ ARAnchors adjust for drift
  5. CAPTURING THE ARWORLDMAP ▸ Dense feature points ▸ Multiple points

    of view ▸ No motion - static environment ▸ Use WorldMappingStatus ▸ Don’t display UI until ready
  6. TESTING IN THE REAL WORLD ▸ Low lighting ▸ Smooth

    surfaces ▸ Moving device fast while mapping ▸ Motion in environment
  7. PERFORMANCE CONSIDERATIONS ▸ Initialization takes some time ▸ Battery drain

    ▸ Limit the number of anchors ⚓ ▸ Delegate callbacks on background threads ▸ Mapping from a distance doesn’t work ▸ Occlusion - no depth sensing
