Hi,
In the past I've used Metaio and Vuforia for some augmented reality apps and one of the things I used was an image as trigger to display my content, this is to place my 3d object or a video based in the position of that image. One example could be to pointing with the camera to a movie poster and adding a video next to it or a character of that film..
So I guess the question is, how could I do that with ARKit?, how am I able to decide the location of my augmentation based in something the user is pointing to?
