The process of creating a 3D model for visualization in the game engine from two-dimensional source data
Source publication
The aim of the study presented in this article is to identify and analyse the problems which arise when creating a 3D model based on two-dimensional data and its import into a game engine and then developing algorithms to automate this process. The authors decided that they would use the Unity game engine to create an application presenting the res...

... adopted in the study process of creating the model, from source data to the final effect was divided into the stages presented in figure 1. Such a division made it possible to define independent data processing activities with well--defined initial and final conditions and to control the process of creating the model at individual stages. ...

A set of classic molecular dynamics simulations at a cooling rate of 0.1 K/ps have been performed to investigate the effect of pressure ranging from 0 to 4 GPa on the solidification of liquid Mg70Zn30 alloy, by means of the average atomic energy, the largest standard cluster analysis and 3D visualization. It is found that pressure plays an importan...
Three-dimensional (3D) representations of the environment are often critical for selecting actions that achieve desired goals. The success of these goal-directed actions relies on 3D sensorimotor transformations that are experience-dependent. Here we investigated the relationships between the robustness of 3D visual representations, choice-related...

The three-dimensional model of this building was created as a result of transformations carried out on source spatial data collected by the Department of Cartography of the Warsaw University of Technology during various scientific and implementation--type projects, including work related to the creation of the Property Information System of the Warsaw University of Technology (Gotlib & Gnat, 2018). The transformations were performed as part of a paper (Janicki, 2020) in which the author used the Unity game engine. The source data were provided in FBX 2 format, which resulted from the preparation of the database according to the Indoor Data Model (IDM) developed by the Department of Cartography of the Warsaw University of Technology. ...

Solutions designed for indoor navigation are extremely rare compared to outdoor navigation; however, the potential for development is, therefore, very high. Several pilot projects exist in airports, universities, hospitals, and shopping centres. The difficulties in development are currently mainly due to the continuing low quality of indoor positioning and lack of widespread access to high-quality building models. A strong methodological basis for how the interior and exterior of buildings can be cartographically represented in navigation applications has also not yet been developed. Therefore, an attempt was made to design a virtual environment dedicated to supporting the design of indoor navigation applications. Authors present the results of a study aimed at creating a concept of a simulation environment accompanied by the assessment and preliminary validation of its technological feasibility in terms of the method and technology used – although it does not yet constitute a target study. The result was a fully functional prototype of a virtual test environment, which was successfully used in a pilot study on the effectiveness of different types of navigation guidance. The participants’ behaviour within the desktop virtual environment was investigated and their opinions were collected through a questionnaire. This research proved the technological feasibility of the proposed concept and demonstrated the usefulness of the Unreal Engine game engine in building new tools to support the work of cartographers. The created environment will be further developed and used in indoor mapping research.
