Occlusion
ARCore provides support for occlusion based on environment depth images it generates every frame. These depth images provide a distance (in meters) from the device to any part of the environment in the camera field of view.
The XROcclusionSubsystem provides access to two types of environment depth: raw and smoothed.
- Raw: The raw, unsmoothed depth data. This is useful for custom processing where raw data is necessary and corresponds to ARCore's ArFrame_acquireRawDepthImage function.
- Smoothed: Depth data with smoothing applied. This is useful when performing occlusion and corresponds to ARCore's ArFrame_acquireDepthImage function.
Requirements
Environment depth requires a device with depth support. See ARCore supported devices for a list of devices that support depth ("Supports Depth API" in the Comments column).
