Later, we integrated a geolocation library so we could place game objects on real-world map points.
That’s when the fun (and math) really started.
When the AR scene launches, Unity creates a local coordinate system – and it’s not aligned with the real world. For example, the in-game X-axis might point south or northeast, depending on how you hold your phone.
To place objects correctly, we had to sync:
- Unity’s local coordinate system
- Real-world GPS (latitude/longitude)
- Compass heading
- And align it all so X points to true north
Tough? Yes. But we cracked it.
