World Reconstruction allows your Magic Leap 2 to query your real-world environment and detect surfaces, constructing a digital map of the space, improving how apps interact with the world around you.
World Reconstruction Best Practices
For better world reconstruction, we recommend the following:
- Moving the device: Move around and explore your space, even looking behind furniture or objects
- Keep motions slow, smooth, and steady: Fast, "jerky" motions are ignored when tracking your space and constructing meshes out it.
- Maintain a proper distance: Don’t get too close to or far from objects and surfaces you are scanning – try to always stay a minimum of 40cm away and a maximum of 5m from surfaces. The best range for good quality World Reconstruction is 1-3m.
- Avoid using the device in crowded or quickly changing environments: Places where many people are walking in front of your Magic Leap's cameras ,or objects are moving around fast or frequently will impact world reconstruction.
- If surfaces do not disappear from the volume when something moves, make sure the sensor can see another surface within 5m behind. If it cannot see another surface behind the area which changed, then it does not know that it can remove these surfaces.
- Some objects may not appear in the reconstruction as they absorb or reflect too much light from the sensors (black objects in particular are problematic) – try scanning from different angles (especially perpendicular to the surface) to reconstruct. Transparent objects (such as objects made of glass) will typically never appear in the reconstruction.
- Avoid viewing the reflection of the real world in mirrors, as this may cause a distorted world behind the plane of the mirror to be reconstructed. This could overwrite real room geometry if there are real objects and surfaces behind the mirror or cause holes or incorrect geometry to appear.
