Plane detection
This page is a supplement to the AR Foundation Plane detection manual. The following sections only contain information about APIs where ARCore exhibits unique platform-specific behavior.
Tip
When developing an AR app, refer to both the AR Foundation documentation as well as the required packages for each platform you support.
Subsumption
ARCore supports plane subsumption. This means that you can include a plane inside another. Unity keeps the subsumed plane and doesn't update it.
Battery life
The ARCore plane subsystem requires a significant amount of energy. You can reduce the thermal impact of plane detection and improve battery life by following these best practices:
Use the Detection Mode property of the AR Plane Manager component to disable either horizontal or vertical plane detection if your app does not require it.
Disable plane detection when your app does not require it. For example, your app might direct the user to discover planes in their environment, then disable plane detection once discovery is complete.
