실시간 3D 렌더링 게임의 제작 환경에서 캐릭터의 움직임은 모션 캡처(motion capture)를 통해 만들거나 애니메이터에 의해 제작된다. 걷기나 달리기 등 일정한 속도로 캐릭터가 움직이는 모션은 캐릭터가 제자리(in place)에서 움직이도록 한 뒤에 게임에서 프로그램에 의해 일정한 속도로 움직임으로써 구현할 수 있다. 하지만 일정하지 않은 속도로 움직이는 모션을 같은 방식으로 적용하면 캐릭터의 이동이 어색해진다. 이런 어색함을 보완하기 위해 언리얼이나 유니티 3D 등의 엔진에서는 루트 모션(root motion) 기능을 사용하고 있다. 그런데 루트 모션을 위한 계층 구조는 애니메이터의 작업 효율을 위한 계층 구조와 다른 측면이 있다. 본 논문에서는 3ds Max를 사용하여 애니메이터 친화적이고 루트 모션에도 적합한 캐릭터 리깅을 제시한다.

Due to the spread of COVID-19, many local governments are burdened with the influx of large-scale tourists. As a climate that values Work-Life-Balance has emerged, interest in individual life and satisfaction is rapidly increasing. In addition, due to the popularity of the metaverse field, many people are increasingly interested in related content. In particular, "Animal Crossing: New Horizons" sold more than 15 million copies in 2020, and is enjoying exchanges of interior design, fishing, and collecting insects here. In line with this trend, this study introduces the development of online fishing games based on Jeju infrastructure. This paper focuses on implementation and development, and in particular, it introduces differentiated games through character animation optimized for developing a topographic model that maximizes the beauty of Jeju Island's topography based on the Unity 3D engine.

This paper describes a 3D modeling system in Augmented Reality environment, named 3DARModeler. It can be considered a simple version of 3D Studio Max with necessary functions for a modeling system such as creating objects, applying texture, adding animation, estimating real light sources and casting shadows. The 3DARModeler introduces convenient, and effective human-computer interaction to build 3D models. The 3DARModeler targets nontechnical users. As such, they do not need much knowledge of computer graphics and modeling techniques. All they have to do is select basic objects, customize their attributes, and put them together to build a 3D model in a simple and intuitive way as if they were doing in the real world.

This paper presents an efficient system for power system education using 3-D computer graphics animation in the PC environment. Several power system phenomena are simulated using Real-Time Digital Simulator. Results are transmitted through on-line communication line to PC for graphic animation, and simulated in the 3-D graphics animation. It can immediately reflect user control input and re-simulated this result. The proposed method was tested on both the sub-synchronous resonance phenomena and multi-bus system. It is expected that the proposed method would be helpful for the operator training as well as power system education.

This thesis represents the integrated 3D DEM using both the process of satellite image and the real value of topographic maps. This DEM is draped on satellite image processed to improve representations of the real world. The 3D visualization and 3D animation with satellite imagery data enables to depict more vivid and realistic world. The paper also describes and implements the natural environmental/ecological information system that consists of 7 modules to manage environmental data systematically through an enhanced user interface. We make use of topographic map, satellite imagery data and several thematic maps. Each module has a user interface enabling to assist particular needs of decision-making for ecological/environmental assessments associated with spatial analysis of ecosystem and classification of the environmental status quo and other purposes.

Nowadays, 3-D(Three-dimensions) is used in various field such as Games, Movies, Animations etc. Especially the Role of 3-D computer graphic is being generalized by turnover of Screen from '2-dimensional' to '3-dimensional'. There are not enough data about 'Motion Capture' even though it plays main function in 3-dimensional movement. 'Motion Capture' could be also unfamiliar for people. And as a matter of fact, the use of this equipment is limited due to its high cost. Therefore, I studied the outline of Digital Motion Capture system and its application to 3-D game Character Animation. And I checked the movement of 3-D Character after transplanting the Motion Data to the 3-D Character. I acquired Motion Data by Optical Motion Capture Equipment which we possess and transplanted it into the 3-D Character then Implemented it as walking, running and hitting which are the basic motions of Expression.

This study analyzed with the case analysis of a series of processes from job analysis survey. And results analysis, and academic achievement in order to transform the curriculum of existing courses into the curriculum of NCS-based courses. Also this study analysed of the existing curriculum. Also analyzed the trend of workforce trends and needs of the broadcasting content industry. Through a needs analysis for the industry and alumni and students, video graphics, video editing and video directing were selected. In this paper, it dealt mainly with respect to the video graphics in a dual job. Modeling capability into the unit through a job analysis, animation, effects and lighting were chosen accordingly based introduction of 3D Graphics. Application of 3D Graphics were derived two courses and selected profiles and performance criteria. This training according to the NCS curriculum for students was evaluated based on the student's job was to investigate the learning ability. Academic achievement were the result satisfaction.

Computer game has become the core part of multimedia area in our knowledge and information based society Recently, computer game has been evolving into on-line 3D games which give players more realism from the existing on-line 2D games. We are competitive in developing on-line 2D games. However, we have difficulties in maintaining the competitive edge in the area of 3D game technologies owing to the limited technologies. In this paper, we design and develop Aria Online, an on-line 3D prototype game using Dream3D. The on-line game supports simultaneous connections of multi -users on each game server and full flexibility on user's view.

얼굴은 성별, 나이, 인종에 따라 다양한 특징을 가지고 있어서 개개인을 구별하기가 쉽고 내적인 상태를 쉽게 볼 수 있는 중요한 도구로 여겨지고 있다. 본 논문은 얼굴표정 애니메이션을 위한 효과적인 방법으로 실제얼굴의 피부조직 얼굴 근육 등 해부학적 구조에 기반한 근육기반모델링을 이용하는 방법을 소개하고자 한다. 제안하는 시스템의 구성은 얼굴 와이어프레임 구성과 폴리곤 메쉬분할 단계, 얼굴에 필요한 근육을 적용시키는 단계, 근육의 움직임에 따른 얼굴 표정생성단계로 이루어진다. 와이어프레임 구성과 폴리곤 메쉬 분할 단계에서는 얼굴모델을 Water[1]가 제안한 얼굴을 기반으로 하였고, 하나의 폴리곤 메쉬를 4등분으로 분할하여 부드러운 3D 얼굴모델을 보여준다. 다음 단계는 얼굴 표정생성에 필요한 근육을 30 개로 만들어 실제로 표정을 지을 때 많이 쓰는 부위에 적용시킨다. 그 다음으로 표정생성단계는 FACS 에서 제안한 Action Unit 을 조합하고 얼굴표정에 따라 필요한 근육의 강도를 조절하여 더 자연스럽고 실제감 있는 얼굴표정 애니메이션을 보여준다.

본 논문에서는 Unity 3D 엔진을 심층 분석하여 게임개발 교육현장에서의 유용성을 검토하였다. Unity 엔진을 이용하면 필드의 제작, 캐릭터 애니메이션 세팅, 스크립트 작성, Asset 관리, 레벨 디자인 등 많은 작업을 하나의 통합 환경에서 수행할 수 있다. 또한 컴파일 과정을 거치지 않아도 게임을 제작하는 도중 언제라도 실행해 볼 수 있기 때문에 개발에 걸리는 시간을 단축 할 수 있다. 본 연구의 초점은 게임 앱 설계 관련 프로젝트의 수행이나 교육용 게임 개발의 학습 모형을 제시하기 위한 과정이다.
