Indicates whether an image is being tracked using the camera image, or is being tracked based on its last known pose. Still in Beta. What I want to understand is: (Where each vector is perpendicular to the other vectors). In the smartphone camera, ARCore can detect the intersection of light rays with its 'hit-testing' feature. Also, the marker should be as close as possible to the object. and We use this information to create an Anchor. Remember, virtual objects need to have a place and be at the right scale as you walk around them. When working from a plane it is relatively easy to derive a pose as you can use the plane normal as the up (y) vector for your model and can pick x and y vectors to configure where you want the model to "face" about that plane. ARCore uses all of these to create an understanding of your environment and uses that information to correctly render augmented experiences by detecting planes and feature points to set appropriate anchors.
