In general, it is best to move slowly and smoothly, while keeping your device parallel to the surface you are scanning. Quick and jagged movements will affect the quality of the scan. It can take a few tries to figure the best technique for the object or scene you are trying to capture.
To start a scan, press the red button once and again to stop. While there is no set limit on scan time, very large scans may not process well so it’s best to take smaller scans and work up to larger ones to see the optimal size. You can also click on the pause button to temporarily stop scanning to reposition yourself.
Here are some other considerations when scanning:
- Note that, if the camera can’t see it, there will be a hole in your model. You may need to pause to reposition yourself to get all angles.
- Avoid shiny objects and windows (reflective surfaces), as well as water and moving objects. If possible, let moving objects/people pass before scanning.
- Set the scanning depth to match just the area you need to scan.
- Try to ensure that your lighting conditions are stable. Avoid high contrast light, shadow and changing light conditions during your scan.
- Plan your scan:
o Scan each surface once (don’t do multiple passes).
o Texture is more important than mesh.
o Use the pause button to go back and catch a missed area.
o Walk the model; Scan parallel to surface as much as possible.
o Do not include your feet or your shadow in the scan.
