Sample text

In movies such as Walt Disney's TRON (1982 version), the real and virtual elements are seamlessly blended. However, AR differs from those effects as it is based on all of the following aspects (proposed by Ronald T. Azuma in 1997): It's in 3D: In the olden days, some of the movies were edited manually to merge virtual visual effects with real content. A well-known example is Star Wars, where all the lightsaber effects have been painted by hand by hundreds of artists and, thus, frame by frame. Nowadays, more complex techniques support merging digital 3D content (such as characters or cars) with the video image (and is called match moving).

Recent generations of smartphones are more adapted to handle this type of problem, being that they are optimized for energy consumption. AR architecture concepts So let's explore how we can support the development of the previously described concepts and the two general AR systems. As in the development of any other application, some well-known concepts of software engineering can be applied in developing an AR application. We will look at the structural aspect of an AR application (software components) followed by the behavioral aspect (control flow).
