  • Various 3D contents are being developed using Unity 3D game engine. In this paper, the 3D content of horseback riding game, the first VR game in the country, is designed and developed. The existing riding simulator is investigated and compared to the VR riding game developed. We consider various games developed using Unity 3D game engine and serve previously developed tangible games. It is expected that development of VR riding games will prepare a new chapter in VR experience-type games. We propose the content development environment and scenario of VR riding game and present the main algorithms and main modules for real-time synchronization. The developed riding game contents are deployed to the riding system and are operated for commercial use in conjunction with the riding device. Through monitoring VR riding system, problems are derived and improvement measures are proposed. We offer a variety of additional development options to make the game more realistic in the future.

  • The SLAM market is growing rapidly with advances in Machine Learning, Drones, Augmented Reality technologies. However, due to the absence of an open source-based SLAM library for developing AR content, most SLAM researchers are required to conduct their own research and development to customize SLAM. In this paper, we propose an opensource-based Mobile Markerless AR System by building our own pipeline based on Visual SLAM. To implement the Mobile AR System of this paper, it uses ORB-SLAM3 and Unity Engine and We experimented with running our system in a real environment and confirming it in the Unity Engine's Mobile Viewer. Through this experimentation, we can verify that the Unity Engine and the SLAM System are tightly integrated and communicate smoothly. Also, we expect to accelerate the growth of SLAM technology through this research.

  • The construction industry, known for its inherent risks and multiple hazards, necessitates effective solutions for hazard identification and mitigation [1]. To address this need, the implementation of machine learning models specializing in object detection has become increasingly important because this technological approach plays a crucial role in augmenting worker safety by proactively recognizing potential dangers on construction sites [2], [3]. However, the challenge in training these models lies in obtaining accurately labeled datasets, as conventional methods require labor-intensive labeling or costly measurements [4]. To circumvent these challenges, synthetic data generation (SDG) has emerged as a key method for creating realistic and diverse training scenarios [5], [6]. The paper reviews the evolution of synthetic data generation tools, highlighting the shift from earlier solutions like Synthpop and Data Synthesizer to advanced game engines[7]. Among the various gaming platforms, Unity 3D and Unreal Engine stand out due to their advanced capabilities in replicating realistic construction hazard environments [8], [9]. Comparing Unity 3D and Unreal Engine is crucial for evaluating their effectiveness in SDG, aiding developers in selecting the appropriate platform for their needs. For this purpose, this paper conducts a comparative analysis of both engines assessing their ability to create high-fidelity interactive environments. To thoroughly evaluate the suitability of these engines for generating synthetic data in construction site simulations, the focus relies on graphical realism, developer-friendliness, and user interaction capabilities. This evaluation considers these key aspects as they are essential for replicating realistic construction sites, ensuring both high visual fidelity and ease of use for developers. Firstly, graphical realism is crucial for training ML models to recognize the nuanced nature of construction environments. In this aspect, Unreal Engine stands out with its superior graphics quality compared to Unity 3D which typically considered to have less graphical prowess [10]. Secondly, developer-friendliness is vital for those generating synthetic data. Research indicates that Unity 3D is praised for its user-friendly interface and the use of C# scripting, which is widely used in educational settings, making it a popular choice for those new to game development or synthetic data generation. Whereas Unreal Engine, while offering powerful capabilities in terms of realistic graphics, is often viewed as more complex due to its use of C++ scripting and the blueprint system. While the blueprint system is a visual scripting tool that does not require traditional coding, it can be intricate and may present a steeper learning curve, especially for those without prior experience in game development [11]. Lastly, regarding user interaction capabilities, Unity 3D is known for its intuitive interface and versatility, particularly in VR/AR development for various skill levels. In contrast, Unreal Engine, with its advanced graphics and blueprint scripting, is better suited for creating high-end, immersive experiences [12]. Based on current insights, this comparative analysis underscores the user-friendly interface and adaptability of Unity 3D, featuring a built-in perception package that facilitates automatic labeling for SDG [13]. This functionality enhances accessibility and simplifies the SDG process for users. Conversely, Unreal Engine is distinguished by its advanced graphics and realistic rendering capabilities. It offers plugins like EasySynth (which does not provide automatic labeling) and NDDS for SDG [14], [15]. The development complexity associated with Unreal Engine presents challenges for novice users, whereas the more approachable platform of Unity 3D is advantageous for beginners. This research provides an in-depth review of the latest advancements in SDG, shedding light on potential future research and development directions. The study concludes that the integration of such game engines in ML model training markedly enhances hazard recognition and decision-making skills among construction professionals, thereby significantly advancing data acquisition for machine learning in construction safety monitoring.

  • 유니티는 2D, 3D 게임 개발 도구로 다양한 물리적인 기능과 쉬운 UI와 에셋을 제공하여 개발자가 쉽게 게임을 제작할 수 있도록 지원한다. 유니티가 제공하는 주요 기능 중 하나인 에셋은 게임 개발과정에서 생성되는 스크립트, 리소스, 프리팹 등의 컴포넌트를 통칭한 것으로 개발자가 만들거나 에셋 스토어를 통해 수집하여 게임 제작에 활용할 수 있다. 즉, 에셋 스토어의 에셋들을 활용할 경우 좀 더 효율적으로 게임을 제작할 수 있다. 그러나 에셋 스토어의 구조상 개발하려고 하는 게임 장르 및 타입에 따라 어떠한 에셋을 적용할 것인지를 구분하기 쉽지 않고 적용 에셋을 찾더라도 이를 응용하여 개발 시스템에 적용하기에 상당한 시간 및 노력이 요구되는 경우도 많다. 본 논문에서는 이러한 에셋 적용문제를 해결하고 개발자의 적은 제어를 통해 효율적인 에셋을 제공할 수 있는 ACE(Adventure Create Engine)에셋 생성 엔진에 대하여 제안한다. ACE는 Unity의 상위 레벨에 존재하는 개발 도구로 최종 결과물로 생성된 패키지를 Unity에 적용할 수 있는 구조로 되어 있다. ACE를 활용할 경우 개발자의 요구에 적절한 에셋을 구축할 수 있으며 게임 개발 시간을 단축할 수 있다.

  • In the game industry, traditional game development way was to develop a game engine in advance before developing game content. This has the disadvantage is the high cost of developing the game engine. Further, there is a problem that the game content are not developed unless the game engine is prepared in advance. In order to solve these problems, the game industry has recently selected a method of purchasing a license for a commercial engine, which is a method for improving the game content development productivity, rather than concentrating on game engine development. In this paper, we describe a game object and the structure in Unity and Unreal Engine 4. We compared the editor interface and the supported development languages in the two game engines. We also implemented a First-Person Shooter game to compare how the player's configuration and event handling differ from the two game engines.

  • This research proposes a prototype for visualizing radar rainfall data using the unity 3D engine. The mashup of radar data with topographic information is necessary for the 3D visualization of the radar data with high quality. However, the mashup of a huge amount of radar data and topographic data causes the overload of data processing and low quality of the visualization results. This research utilized the Unitiy 3D engine, a widely used engine in the game industry, for visualizing the 3D topographic data such as the satellite imagery/the DEM(Digital Elevation Model) and radar rainfall data. The satellite image segmentation technique and the image texture layer mashup technique are employed to construct the 3D visualization system prototype based on the topographic information. The developed protype will be applied to the disaster-prevention works by providing the radar rainfall data with the 3D visualization based on the topographic information.
