Unity game engine as a method of presentation of data collected from UAV

Representatives of the scientific community collect and store huge amounts of spatial data resulting from years of their studies. However, there is a common problem of visualization methods of data which would be interesting to understand for a recipient from outside of the area as well as according to the current trends. In the modern day, many spheres of our life have been moved to the virtual reality and that is why representatives of areas such as industry, science, culture and art need to deal with the representation of the real world in a 3D reality.

 

This work is concerned with the current issue of visualization of spatial data collected by surveyors as well as representatives of many other areas. The proposed method of presentation of collected research data is not only low-cost at preparation but is also distinguished by its simplicity of implementation. Its functionality will be presented by using an example of the Agora area located in the Archaeological Park of Kato Paphos in Cyprus. The mentioned area was created in order to protect and promote the archaeological sites as well as the artefacts from the former epoch which have been found in the area. Such historic places are very often not fully available to see by visitors and that is why the documentation and visualization of them in 3D reality might be incredibly helpful. This kind of activity not only contributes to the popularization of archaeological research but also meets the expectations of a modern recipient who uses virtual reality more and more often in order to learn about new places. It is worth mentioning that the presented visualization of measurement data is a versatile method that is intended to be used in many different scientific and research areas.

 

From a technical point of view, the presented work guides a recipient through the complete process of development of an advanced animation in the environment used in the creation of 3D computer games – the game engine Unity. In the first part of the article the suitability of the data results obtained in digital photogrammetry as well as laser scanning was estimated for purposes of applying the presented method. The work also brings up the issues of limitation of free software and raises a question of methods allowing to meet the requirements with minimized loss of quality and accuracy of the data. The next step was to present the method of importing data (a mesh model and a high-resolution texture). Operating mechanism in Unity as well as a transfer of interactive visualization into the online browser Unity Connect were discussed in the further part of the article. It is worth mentioning that thanks to the FPP (First Person Perspective) technique the developed visualization allows a user to be transferred right into the centre of the archaeological sites where the admission for the third party is usually significantly restricted.
