Recently I use some XR features and I have a question about title. I think plane-detection use image analysis and hit-test use ray casting(maybe ray cast use image analysis). However hit-test feature cant detect clearly between desk and floor. I think this feature can cast these object because ray is point not surface.
Maybe this question should be on WebXR site(I don’t know name). Sorry complex english.
The hit test results are being delivered by the underlying system. In case of AR on android, it is the android ARCore that is in charge of processing the image and provide accurate hit testing. It does have its limitations and sometimes doesn’t work as expected, that’s true. But they are constantly improving the detection.
The question should actually be presented to the OS of your choice (which i assume is android).
