These possibilities are implemented in the virtual assembling environment of AR, where engineers and designers can see important visual information about an exact position and orientation of the single composite element that creates a part of the entire composite assembly. By means of this the application of the AR allows costumer to visualize and see the moving process of single composite layer according its trajectory and prevents the mistakes in the assembling processes. Key-Words: - Augmented Reality, logical loops, composite layers, Lay-up (manual) 1 Introduction This paper approaches basic problems and structural logical elements of the essential section of the Augmented Reality (AR), which is understood as visualization process where real environment is covered by virtual one and from the viewpoint of its user together they, present one working space. The main idea of the AR and basic process algorithms are explained by means of concrete examples in the particular points of this contribution. After general expressions it provides the information about advances of composite assembling cycle visualization that brings science view into area of these problems. Such information is necessary and needy for engineering tasks of the designer in the difficult processes of creation of the composite structure. The entire structure of this article is focused on the characterization of steps that follow each other while describing information flow between logical blocks which create general connection for the AR. The first part of the paper deals with data which concern application environment where the mentioned AR was created. This part comprises important information about special visual virtual tools which were applied during the creation of this application. By using these tools, the application allows for designer to manage an entire data flow between different logical cores of the application. The next parts provides the exact view on the single logical areas where the necessary data are harvested and compared with values from virtual arrays and then they are sent to the displaying section of the AR. After that, the article deals with solutions for the AR application of composite process visualization where the designer is able to see the process of the moving of the particular composite ply according the applying trajectory and the final position for all composite layers with their own boundary edges. Final part of the article is focused on the special programming packet and improving elements which increase entire quality of the visual area of the AR. As mention before, an augmented reality system generates a complex view for the user. It is a combination of the real scene viewed by the user and a virtual scene generated by the computer that augments the scene with additional information. Thanks to its possibilities if finds the utilization in many industrial areas [1]. 2 Augmented Reality Visualization During the process of the composite layers application designer stands before many problems and their results have a strong influence to the final conditions of composite structure. In the first phase of creation of the composite construction the single composite layers must be defined by using of special composite modules which are implemented Advances in Sensors, Signals, Visualization, Imaging and Simulation ISBN: 978-1-61804-119-7 142
