Abstract:

Introduction:
The Mixed Reality (MR) combines virtual and real objects. With Mixed Reality, we can present, in attractive and exciting way, virtual content (e.g. architectural visualizations, virtual prototypes, marketing and sales of products and entertainment systems that are not created yet) in the real context of various application areas. These types of scenarios require a realistic version where the people should to believe in the appearance of the virtual objects that will provide a perfect illusion of human visual perception. Unfortunately, in general mixed-reality systems, this requirement is not met and the images appear disturbingly artificial.

Presentation:
The aim of one Mixed Reality Application is to integrate virtual objects into real environments in a way that in ideally case the both objects (real and virtual) are indistinguishable. Therefore, this can be a technology for visualizations of architectural objects, visualizations of product and cultural heritage sites, where the virtual objects should be seamlessly integrated with real ones. Thanks to the improved performance of the modern graphics software, we can apply global algorithms, used in real environment, in mixed reality applications, and thus more and more researchers consider realistic representation in a system with mixed reality.

Results:
In this report, we will present how to create realistic objects in a mixed reality system. We will illustrate the usage of different lighting models, and assessment methods, and which of them to choose. We will demonstrate our examples in the Unreal engine, which is game engine. In addition, we will present the possibility to use ready plugins in combination with 3D objects, created by photogrammetry. Another result that we will present in our article is the ability to export ready scenes and their application in the creation of videos. Therefore, in this article, we will present our analysis of the application of mixed reality in learning. The students showed great enthusiasm when we conducted several lectures from distance for COVID-19. In the report, we will describe the difficulties we had to deal with.
