Markerless
Markerless Augmented Reality does not use a marker. In lieu of a marker, you launch the experience by selecting the AR feature in an app or website or clicking a link. Though markerless AR is common in apps, it also works well with WebAR.
Markerless Augmented Reality scans the real environment and places digital elements on a recognizable feature, like a flat surface. So, instead of being tied to a marker, the digital elements are placed based on geometry. Markerless Augmented Reality is very popular in gaming, like Pokémon Go, where characters can move around the environment. It is also often utilized for live events and virtual product placement.
