Mesh classification
Understand the mesh classification feature.
In AR Foundation 6.4 and newer, you can enable mesh classification on supported platforms to apply semantic labels of detected meshes. Enable mesh classification to improve understanding of the real-world environment.
Uses for mesh classification
Mesh classification enables you to use semantic labels of meshes to improve your app's understanding of the physical environment. You can use these semantic labels to improve features of your application that rely on understanding of the physical environment, for example:
- Accurate physics
- Object placement
- Navigation
Enable mesh classification
There are two ways to enable mesh classification:
- Open the ARMeshManager in the Inspector window, and enable Classification.
- Use the submeshClassificationEnabled API.
Note
Some platforms might require a restart of the XRMeshSubsystem to enable mesh classification via scripting.
Once you have enabled mesh classification, you can use TryGetSubmeshClassifications to obtain classifications using Mesh ID.
