Scanning Best Practices

When scanning we recommend the following for best results.

• Imagine your iPhone/iPad is a spray can and the captured points are paint
  • Try to get a smooth, even coat of paint over the entire area you would like to scan, and make sure you get in all the nooks and crannies!
  • Avoid jerky movements while scanning and limit large left<->right rotations

• When possible, keep your device between 3 - 12 feet (1 - 4 meters) away from the things that you’re scanning

• 1Avoid scanning outdoors or in direct sunlight
• • If you need to scan outdoors, wait for an overcast day, and plan to scan during the ~3 hours after dawn or before dusk.

• Make sure your iPhone/iPad does not get too hot
  • If the ambient temperature is over 75°F (24°C) or if you are making multiple scans in a row, try to let the back of your device cool as much as possible before starting a new scan. If the device gets too hot it will throttle the CPU, drastically reducing scan performance.

• Make sure your iPhone/iPad has at least 50% battery

• Try to always keep feature-rich objects (ie. things with clear details or sharp edges) in the frame while scanning.
• • Looking only at homogeneous objects, like blank walls or noisy objects like carpet or grass, for more than a couple of seconds can cause the iPad’s tracking to drift which will miss-align points.
