Searches for real-world objects or AR anchors in the captured camera image.
- iOS 11.0+
A point in normalized image coordinate space. (The point
(0,0)represents the top left corner of the image, and the point
(1,1)represents the bottom right corner.)
The types of hit-test result to search for.
A list of results, sorted from nearest to farthest (in distance from the camera).
Hit testing searches for real-world objects or surfaces detected through the AR session's processing of the camera image. A 2D point in the image coordinates can refer to any point along a 3D line that starts at the device camera and extends in a direction determined by the device orientation and camera projection. This method searches along that line, returning all objects that intersect it in order of distance from the camera.
