In this study, we investigated optimization methods applicable to Unity 3D and evaluated the efficienc y of optimized content through experiments. And by applying this, we created virtual reality content with the th eme of survival set in space. In this experiment, virtual reality space survival content was built on the Android OS platform, and CPU processing speed, total memory usage, draw call, and FPS were measured using Unity P rofiler, and the performance before and after applying the optimization technology was compared and presented i n a table. . As a result, it was found that the 3D content optimization methods proposed in this study, includin g 'Lighting Baking', 'Occlusion Culling', 'Object Pooling', and 'Asynchronous Scene Loading Using JSON', wer e very efficient in VR devices. This study proposes a way to easily solve the optimization problem, which is a chronic problem in the development of 3D content to be used in VR devices, in the Unity engine, providing a useful guideline for indie game developers or people unfamiliar with the Unity engine when developing VR con tent. I hope it will be used.

This research is the study of raindrop rendering. In case of rendering for raindrop in existing games, it is used on sprites images or roughly raindrops images using texture rendering. These methods are similar to the shape and size of all rendered raindrop. That's why players are limitations to provide a sense of reality. To overcome this limitation, this paper proposes a method for generating raindrop considering surface tension and contac angle, the amount of water, implements the raindrop using Unity3D engine. To demonstrate the usefulness of this paper, this paper shows the generated raindrop in accordance with the change in the area and pulling force in surface tension formula. This paper can help to provide the actuality in game in case of rendering the raindrop.

본 논문에서는 레이싱 게임에서 도시 맵을 빠르게 생성 및 합성할 수 있는 알고리즘을 제안한다. 레이싱 분류의 게임은 고정된 영역이 아닌 넓은 영역을 이동하는 특징이 있지만 이를 위한 맵을 디자인하고 개발하는 것은 많은 시간을 요구한다. 이 문제는 큰 지형 맵을 전처리 과정에서 생성함으로써 완화 시킬 수 있지만 고정적인 맵은 게임을 지루하게 만들며 그렇다고 다양한 맵을 모두 전처리 과정에서 처리하는 것은 비효율적이다. 이 같은 문제를 해결하기 위해 우리는 전처리 과정에서 지형 패턴을 만들어 실시간에 맵을 생성하고 다양한 맵을 랜덤하게 합성 할 수 있는 기법을 제안한다. 또한, View-dependent기법을 제안하는 프레임워크를 통합시켜 불필요한 렌더링 계산을 줄임으로써 효율성을 증대시킨다. 본 연구는 Unity 게임 엔진에서 개발했으며 레이싱 게임뿐만 아니라 다양한 콘텐츠에서 활용할 수 있다.

Recently, metaverse has attracted great attention worldwide with the development of related technologies and the demand for on-tact systems. The ideal metaverse should constitute a virtual world more similar to the realistic society with physical interactions. However, there are many constraints when we construct a virtual world using the existing commercialized metaverse platform. In this paper, we design and implement a university campus-based metaverse which minimizes the constraints, and create a virtual environment maps very similar to the real-world using Unity engine, Photon cloud and Playfab SDK for multi-user accessible to virtual world as a personal avatar. Also, this work includes attractive interaction based on exchange between users. Lastly, we illustrate our implemented metaverse works on Android phone, and it works without difficulty in terms of performance.

In the recent gaming industry, the paradigm has been changed with upcoming core-platform as time goes by. Arcade, console, PC online and smart device platforms are representative ones. In recently, the platform is changed to multi-platform which connecting to smart device and other platforms. Besides, the multi-platform without PC is up-coming. This paper suggests that a kind of multi-platform which connecting from smart devices to arcade devices be aware of lack of continuous. It provides a new arcade gaming condition connecting to smart devices, then supplies online network conditions to the arcade gaming machine. The original arcade game was lack of continuous and the game platform was so simple, but now, it could be focused from players by connecting to smart devices to increase the gaming machines' continuity. Furthermore, Bluetooth communication module and wireless Wi-Fi communication module are used to adapt various communication environments. The Unity3D engine would make contents' expandability.

As the number of augmented reality games using augmented reality technology increases, the demands of users are also increasing. Game technologies used in augmented reality games are mainly games using MARKER, MARKERLESS, GPS, etc. Games using this technology can augment the background and other objects. To solve this problem, we want to help develop augmented reality games by analyzing objects in the background, which is an important element of augmented reality. To analyze the background in the augmented reality game, the background object was analyzed by applying a deep learning model using TensorFlow Lite in the UNITY engine. Using this result, we obtained the result that augmented objects can be placed in the game according to the types of objects analyzed in the background. By utilizing this research, it will be possible to develop advanced augmented reality games by augmenting objects that fit the background.

The 3D game graphic technology has become an important factor in the contents field with the game contents development. In particular, game character technology provides a realistic technique and visual pleasure, as well as an intermediate step in the immersion of the game in which the game might create an optical illusion that enables the player to enjoy heroic adventure in the game. The high expression level of characters in 3D games is a key factor in the development process, with details and carefulness of the character setting work [3]. In this paper, we propose a character representative technique applied to mobile games using mathematical model of radiosity energy, spectral radiance model, and ray tracing model method using 3D unity game engine with sensible AI algorithm for game implementation. As a practical application to the game contents, it was found that the projection of the surface in the rendering process and the game simulation might change according to the lighting condition of the game content environment, so that the high quality of game characters was simulated.

NPC in game is an important factor to increase the fun of the game by cooperating with player or confrontation with player. NPC's behavior patterns in the previous games are limited. Also, there is not much difference in NPC's ability among the existing games because it's designed to FSM. Therefore, players who have matched with NPCs which have the characteristics may have difficulty to play. This paper is for improving the problem and production and evaluation of the game NPC behavior model based on wolves hunting model in real life. To achieve it, first, the research surveys and studies behavior states for wolves to capture prey in the real world. Secondly, it is implemented using the Unity3D engine. Third, this paper compares the implemented state transition probability to state transition probability in real world, state transition probability in general game. The comparison shows that the number of state transitions of NPCs increases, proportions of implemented NPC behavior patterns converges to probabilities of state transition in real-world. This means that the aggressive behavior pattern of NPC implemented is similar to the wolf hunting behavior pattern of the real world, and it can thereby provide more player experience.
