Real-time 360 VR (Virtual Reality) stereo image acquisition technique based on game engine was proposed. However, GPU (Graphics Processing Unit) resource is not fully utilized due to bottlenecks. In this paper, we propose an improved GPU scheduling technique to solve the bottleneck of the existing technique and measure the performance of the proposed technique using the sample games of the commercial game engine. As a result, proposed technique showed an improvement of performance up to 70% and usage of GPU resources more evenly compared existing technique.

Commercialized game engines help develop content and support various platforms, but there are performance differences depending on the function. In this paper, a VR video conferencing platform corresponding to source multi-use was implemented, and the connection delay time according to the type of game server engine and the number of platform users was measured. As a result of the measurement, the latency was the lowest at 22.146 msec when using the Amazon GameLift engine and with 2 users, and the latency was the highest at 27.007 msec when using the ProudNet engine and with 10 users.

In this paper, we propose a multi-stage user authenticating system in which system at first stage, the system authenticate a user through his GPS information and IP address. At second stage, the system authenticate a user based on ID and Password as other systems does. Through the use of proposed system, aged person or children enjoy the game on a much safer environment.

Interior Mapping has been used to reduce graphics resources. In this paper, rendering speed(FPS), the number of polygons, shader complexity and each resource size of Interior Mapping were compared to those of actual modeling in order to examine the performance of 3D games when the technology is adapted by utilizing Unreal Engine 4. In addition, for the efficient application, the difference in performance according to the resolution and detail of cube map texture was verified.

This paper proposes a remote partitioned rendering method for displaying 3D applications on large tiled displays, which were developed using the Unity game engine. With the proposed method, one can represent them without additional development or any modifications to the applications. The paper verifies its feasibility by applying to a sample Unity-based application.

Recently, increasing numbers of games and simulators are being implemented by employing the physically-based modeling techniques for better realism. In this paper, we propose the implementation techniques for overhead crane simulator based on ODE, the well-known open source dynamic engine. By comparing the dynamic behavior of the proposed system with a commercial engine based simulator, the physical plausibility and the effectiveness of the ODE based OHC simulator are verified. We expect the proposed the OHC simulator can be successfully utilized for virtual training in various educational institutes.

CEP(Complex Event Processing) is a technique to find complex event pattern in a massive information system. Based on CEP technique, an abuse pattern monitoring method has been developed to provide an real-time detection. In the method, the events occurred by game-play are observed to be against the rules using CEP. User abuse patterns are pre-registered in CEP engine. And CEP engine monitors user abuse after aggregating the game data transferred by game logging server. This article provides the performance analysis results of the abuse pattern monitoring method using real game DB. We results that the method proposed in previous study is effective to monitor abusing users.

This paper studied various low power structures of texture caches for mobile 3D graphics accelerator to reduce the memory latency of texture data. Also the paper designed the texture cache with the variable threshold values of power mode transition according to the filtering algorithms. In the trace driven simulation, we compared the performance of those structures using Quake game engine as the benchmark. Also the algorithm was proposed and verified by the simulation, which has variable threshold values of power mode transitions according to the selected texture filtering method.

최근 가상현실을 활용한 게임콘텐츠들이 많이 제작되고 있다. 그러나 킬러콘텐츠가 부족한 상황이며 가상현실 게임을 즐기기 위해 사용하는 HMD(Head Mounted Display)는 멀미감 때문에 장시간 사용하기 힘들다. 본 연구에서는 멀미감을 최소화할 수 있는 퍼즐과 요즈음 오프라인에서 인기가 있는 방탕출 게임을 동시에 즐길 수 있는 콘텐츠를 제안한다. 특히, 개발한 콘텐츠는 Unreal Engine을 사용함으로서 게임에 현실성을 더욱 가미할 수 있었고 남녀노소 누구나 즐길 수 있는 범용적인 콘텐츠이다. Unreal Engine을 활용한 게임이 별로 많지 않아 본 콘텐츠는 향후 Unreal Engine를 활용한 게임을 제작하는데 도움이 될것이라 사료된다.

본 논문에서 제안하는 슈팅게임 제자작 방법은 게임엔진으로 언리얼 엔진 4(Unreal Engine 4)를 사용하고 있다. 기존의 언리얼 엔진 기반의 게임은 총알에 데미지 판정 기법을 사용하지만, 슈팅게임 제작에서 중요한 요소인 정확성을 높이기 위해서 Line Trace 기술을 활용하는 기법을 제안한다.
