You can check which platforms support AR Foundation Anchors features by checking the Anchors platform support page.

Anchors scene

The anchors sample scene shows how to create anchors as the result of a ray cast hit. The Remove all anchors button removes all created anchors.

The ARAnchorManager can create two kinds of anchors based on a ray cast hit:

• If the ray hits a feature point, it creates a normal anchor at the hit pose using the TryAddAnchorAsync method.
• If the ray hits a plane, it creates an anchor attached to the plane using the AttachAnchor method.

Anchor visualizer

The AR Foundation Samples GitHub repository contains a prefab to visualize anchors in your scene. You can use this prefab to get that you can use to get started with visualizing anchors:

Prefab	Description
