The following tutorial helps you experience environment occlusions on LiDAR enabled iOS devices
Create environment occlusions based on LiDAR data
From ARki 7.1 you can visualise accurate object occlusions in the real-world so that placement of 3d models can be occluded behind physical objects as shown in the video.
Surface -> Mesh
This visualises the Lidar Mesh that is being captured in real-time
Surface -> Occlusion
This toggles on object occlusion based on the mesh that LiDAR captures.
*Please note if you are using a large model in the scene, switching on Occlusion may lower the frame-rate of the AR experience.
