In the era of rapid technological transformation linked to Industry 4.0, research topics in the field of Computer Graphics have expanded and deepened to respond to the increasingly demanding needs of several applications, such as e-learning, maintenance, art, marketing and advertising, social networking, psychology and medicine. The diversification of needs has led research in this field to use technologies ranging from virtual reality, in which the user acts in a fully digital environment that guarantees a high level of immersion, to augmented reality, which allows the integration of virtual elements with the surrounding elements of the real world. Research in this area deals with the conceptualization and implementation of applications that make use of these technologies relying on different design needs. This includes the possibility of making different users interact in the same virtual scenario, which makes the experience conform to the paradigm in the metaverse.
