Spatial Mapping

Definition

Spatial mapping is the process of creating a digital representation of a physical environment, allowing virtual objects to interact realistically within that space. This technique is crucial for achieving accurate anchoring of digital content in the real world, ensuring that virtual elements remain stable and responsive to changes in user perspective or environment. Effective spatial mapping enhances user experiences by integrating augmented and virtual elements seamlessly into real-world settings.
