ARCore tracks a device's position using feature points, creating a model of the space, and identifying surfaces (planes). It renders virtual content from the correct perspective, combining the real and virtual world. However, limitations such as featureless, dim, reflective, or dynamic surfaces can affect tracking accuracy and the model's quality.\n"]]
