Actions

Get Current Frame

Returns the last processed FAppleARKitFrame from the session.

When called from the game thread, we ensure a single frame is returned for the duration of the game thread update by watching for changes to GFrameNumber to trigger pulling a new frame from the session.

Target is Apple ARKit Blueprint Library

Hit Test at Screen Position Tracking Space

Searches the last processed frame for anchors corresponding to a point in the captured image.

A 2D point in the captured image's coordinate space can refer to any point along a line segment in the 3D coordinate space. Hit-testing is the process of finding anchors of a frame located along this line segment.

NOTE: The hit test locations are reported in ARKit space. For hit test results in game world coordinates, you're after UAppleARKitCameraComponent::HitTestAtScreenPosition
