In this segment of the video, dynamic occlusion in virtual reality is discussed. The speaker demonstrates how virtual content can hide real-world objects, such as hands or bodies, when interacting with VR content. The importance of dynamic occlusion in creating realistic visual interactions between virtual and physical content is emphasized. The speaker introduces the depth API from Meta, which provides real-time depth estimates for rendering more believable VR experiences. To utilize this feature, developers must enable experimental features on the headset by running an ADB command and may need to utilize projects shared on GitHub.

In this segment of the video, the speaker discusses implementing changes for mixed reality settings. Developers must decide between using planes or depth scanning for reconstruction, and where to place the video layer in relation to virtual content. The speaker demonstrates how the system updates the environment mesh dynamically, even capturing movements like hand gestures, with options for soft or hard occlusion affecting the visual accuracy. Soft occlusion is more visually appealing but demands more processing power, while hard occlusion is cheaper but may have jagged edges. The video showcases these features by illustrating how hands interact with virtual objects in the environment, highlighting the differences between the occlusion options.

In this segment of the video, the speaker highlights the groundbreaking feature of dynamic occlusion on the Quest 3, showcasing how virtual content can interact realistically with physical objects. They demonstrate examples like placing a torch behind a physical object, showing improved accuracy with straight lines using hand tracking, and how virtual content can now exist both behind and in front of physical objects. The speaker notes that while this feature is revolutionary for mixed reality, it is not widely used by developers yet due to its intensive computing power requirements and experimental status. They express excitement for the potential improvement of this feature with better hardware and algorithms, emphasizing its significance for mixed reality experiences.
