How AR objects can truly belong in their environment

In this article, we are going to show what occlusion is and how it works in Wintor.

Occlusion helps your AR tours look more realistic and connected to the environment — making digital objects appear as if they truly exist within the physical space.

What Is Occlusion?

Occlusion allows virtual elements to disappear or hide behind real-world surfaces.

When you walk around an AR scene and a digital object moves behind a real wall or statue, it doesn’t just overlap the camera image anymore; it reacts to the environment.

This effect creates a natural sense of depth and realism, helping AR objects visually “belong” to their surroundings.

How It Works in Wintor

In Wintor, occlusion works by placing a 3D model or scanned surface directly over the real-world object you want to use as a depth layer. Then, by enabling the Occlusion option in the settings, that model becomes invisible to the viewer but still blocks virtual items behind it.

This means:

People see the real-world object through their camera,
The app sees the occluding 3D surface,
And any AR content placed behind that surface will correctly appear hidden.

This method provides precise and consistent occlusion without depending on LiDAR sensors or device-specific depth data. In our tests, this approach proved more stable and more accessible to all users, even on devices without LiDAR, and produced cleaner edges compared to hardware-based occlusion, which often introduces soft or blurry transitions.
