A point on a surface detected by ARKit, but not part of any detected planes.
- iOS 11.0+
During a world-tracking AR session, ARKit builds a coarse point cloud representing its rough understanding of the 3D world around the user (see
raw). Individual feature points represent parts of the camera image likely to be part of a real-world surface, but not necessarily a planar surface.
When you search using this hit-test option, ARKit finds the feature point nearest to the hit-test ray (the extension of the 2D hit-test point into 3D world space), then returns the point on the ray nearest to that feature point.
