UNITY | AR DEVELOPMENT | AR FOUNDATION PACKAGE | PLANE MANAGER
Setting up Plane Detection in Unity AR
Configure Application to Detect and Visualize Planes
STEPS NEEDED
- PLANE MANAGER Component | XR ORIGIN (AR) GameObject
- Create & Configure a Default Plane Prefab
STEP ONE — Plane Manager Component | XR Origin (AR) GameObject
XR ORIGIN (AR) > Add Component > AR Plane Manager
The Plane Manager is a type of Trackable Manager that creates, updates, and removes GameObjects in response to detected surfaces in the physical environment. It also creates GameObjects within our scene to visually represent each plane it creates based on a referenced Plane Prefab.
A plane is a flat surface represented by a pose, dimensions, and boundary points. This data is then used to form a shape without any inward dents (convex).
The Plane Manager also has a Detection Mode setting which can be specified to detect horizontal planes (Tabletops, Countertops, floors, etc.), vertical planes (Walls, Fences, etc.), or both.
STEP TWO — Create & Configure a Default Plane Prefab
Scene > Create > XR> AR Default Plane
The Default Plane Prefab is what will be used to display the planes within the scene.
The Default Plane works pretty much out-of-the-box, but for slight customization, the material choice is going to be reconfigured to a transparent green. Once the Default Plane is configured to be a prefab, it then needs to be referenced within the Plane Manager Component.
