Occlusion

This page is a stub, please expand it if you have more information.

Occlusion happens when one object in a 3D space is blocking another object from view. In AR, computer-generated objects are placed in a real scene to provide additional information or change the nature of real objects. Thus, the virtual objects and the real scene has to be perfectly aligned in order to maintain high levels of realism and enable objects to behave how they would under normal conditions.

Occlusion also present significant challenges in positional tracking. The problem is especially prominent in optical-based tracking systems when objects are hidden from the tracking camera because they are behind other objects.
