Since 3D gamers can control points of view and field of view freely, 3D games generate high realities and immersions. On most of 3D games, a point of view and a field of view are determined by positions and FOV(field of view) of camera. Although FOV is a simple technical factor, it leads to graphics distortion and affects immersion of the game and causes some gamers to get physical sickness. Therefore, we will suggest the instruction to operate FOVs in many 3D games by examining and analysing various rendering results with control of FOV and real cases of FOV in published games with same 3D modeling environments.

The development of image technologies in such area as broadcasting and movies has recently increased our attention to 3D stereoscopic images. In addition, the development of stereoscopic image representation technologies in 3D contents becomes more active over time due to the representational limitations of 2D images. Without limitation to the above-mentioned area, stereoscopic image technologies have been developed and studied so that they can be widely accessed in diverse areas including medical services and education. Due to the refined production, however, required to represent a three dimensional effects and the fatigue caused by the perception of a three dimensional effects, the stereoscopic image technologies are not combined into real time systems such as games where environments change unforeseeably. In this study we design a technique to adjust the depth scaling that will enable efficient management of a three dimensional effects and to relieve fatigue through automatic view point interval adjustment in accordance with situations based on the geometrical structure of the DirectX SDK graphic pipeline. Through this, we would like to suggest a new alternative idea to activate the production of games combined with stereoscopic image technologies.

본 논문에서는 온라인 비대면 교육환경에서 메타버스 플랫폼을 활용한 게임제작프로젝트의 PBL(Project-Based Learning) 교수법 운영방법을 예시를 통해 제시한다. 본 연구에서는 C 대학교 게임전공의 2, 3학년 학생들이 수강한 게임제작프로젝트 관련 수업에 게더타운 메타버스 픝랫폼을 활용한 비대면 PBL 교수법을 적용하였다. 이 수업을 위해 게더타운 플랫폼에 실제 실습실 및 작업공간과 유사한 환경을 2D 디지털 가상세계를 구축하였고, 이 플랫폼에서 오리엔테이션, 팀빌딩, 프로젝트 진행 및 피드백 등 PBL 교수법을 적용하였다. 게더타운 플랫폼을 활용한 PBL 교수법 적용 결과 최종 산출물의 퀄러티는 기존 대면으로 진행했을 때와 크게 다르지 않았음을 확인하였다.

The recent Neural Network technique has shown good performance in content generation such as image generation in addition to the conventional classification problem and clustering problem solving. In this study, we propose an image generation method using artificial neural network as a next generation content creation technique. The proposed artificial neural network model receives two images and combines them into a new image by taking color from one image and shape from the other image. This model is made up of Convolutional Neural Network, which has two encoders for extracting color and shape from images, and a decoder for taking all the values of each encoder and generating a combination image. The result of this work can be applied to various 2D image generation and modification works in game development process at low cost.

With the recent introduction of HMD devices, there is a growing interest in simulator games that are difficult to experience directly like a FPS, racing game. However, because these gaming require a large volume consol and a additive user manipulating devices for the more reality experience, most of these games are very expensive. Therefore, we propose the Arduino Air Mouse for a sniper simulator game, which maximizes realism and can be enjoyed with small volume and low cost devices. The implemented Arduino Air Mouse uses an acceleration sensor and gyro sensor. Specially, after this device was tested in the a sniper simulator game that is applied the ballistics in the Unity3D environment, the implemented game showed more reality.

This study is a VR system design designed to evaluate the impact of interaction on user experience analyzed by developer's perspective for the interactive VR fashion show. In the VR fashion show design, we produced an interactive system through the four interactive elements of camera viewpoint, cloth, effects, and sound. The interactive design system is proposed based on three application facto rs in VR space design: speed, range, and mapping. The study focused on the user experience based on format conversion to apply the Unity3D engine using 3D model, animation, 2D UI design, and simulation.

Most game players obtain more satisfactions by interacting with human players that have fluxed behavior patterns, than with NPC(Non-Player Character)s that have fixed behavior patterns. Since it is impossible that game players always interact with human players, adaptive NPCs that can variously behave are required. In this paper, we present a method to create adaptive NPCs using a dynamic FSM(Finite State Machine). This method configures a dynamic FSM by using behavior information at behavior database, and repeatedly updates the dynamic FSM so that the dynamic FSM's total efficiency approaches to a given target efficiency. NPC adapts to game players through this process. For an experiment, we have implemented a 2D game with this strategy, and experimented with various target efficiencies. We show that a dynamic FSM's total efficiency approaches to target efficiency by updating a dynamic FSM several times over. It means that the adaptive NPC to be generated, adapts to game players.

컴퓨터 기술의 발전에 따라서 게임분야 역시 다양한 첨단 기술이 적용되고 있다. 예를 들면 강력한 3D가속 기능을 가진 비디오카드, 5.1 채널 사운드, 포스피드백 지원 입력 장치, 운전대, 적외선 센서, 음성 감지기 등이 게임의 입출력 인터페이스로서 이용되고 있다. 전형적인 방법 이외에도 광학방식이나 휴대용 게임기에 대한 플레이 방식에 대한 연구도 활발하다. 최근에는 비디오 게임기에도 사람의 동작을 인식하여 게임의 입력으로 받아들이는 기술이 상용화되기도 하였다. 본 논문에서는 이런 발전 방향을 고려하여 차세대 게임 인터페이스의 방식으로서 사용될 수 있는 사람의 표정 인식을 통한 인터페이스 구현을 위한 접근 방법들에 대하여 고찰을 하고자 한다. 사람의 표정을 입력으로 사용하는 게임은 심리적인 변화를 게임에 적용시킬 수 있으며, 유아나 장애자들이 게임을 플레이하기 위한 수단으로도 유용하게 사용될 수 있다. 영상을 통한 자동 얼굴 인식 및 분석 기술은 다양한 응용분야에 적용될 수 있는 관계로 많은 연구가 진행되어 왔다. 얼굴 인식은 동영상이나 정지영상과 같은 영상의 형태, 해상도, 조명의 정도 등에 따른 요소에 의하여 인식률이나 인식의 목적이 달라진다. 게임플레이어의 표정인식을 위해서는 얼굴의 정확한 인식 방법을 필요로 하며, 이를 위한 비교적 최근의 연구 동향을 살펴보고자 한다.

The procedural generation algorithm is an algorithm that automatically generates a content to be used in a game by repeatedly executing a series of rules. As the size of the game increases, the amount of content used in the game increases. Accordingly, artificial intelligence research is actively conducted to automatically generate game contents using game artificial intelligence such as procedural generation. In this paper, we propose an algorithm to create 3D game world using procedural generation. The proposed algorithm generates a two-dimensional contour in which the path is naturally connected using Perlin-Noise whose noise is gradually changed. A three-dimensional Height-Map is created based on the generated two-dimensional contour lines. The generated Height-Map show that the shape of the map is normal and that the player is able to move around all the sections as in the game world created by hand. In the future, we will improve the performance of algorithms and apply them to game.

We present a reinforcement learning-based framework for generating 2D Lego puzzle from input pixel art images. We devise heuristics for a proper Lego puzzle as stability and efficiency. We also design a DQN structure and train it to maximize the heuristics of 2D Lego puzzle. In legorization stage, we complete the layout of Lego puzzle by adding a Lego brick to the input image using the trained DQN. During this process, we devise a region of interest to reduce the computational loads of the legorization. Using this approach, our framework can present a very high resolutional Lego puzzle.
