Game industry will be one of the fastest developed industries in the 21st century. It is the outcome derived from the development of hardware such as the accumulated technology and computer in the 20th century. The development of computer graphics and hardware technique has let games have more realistic expression. The reality shown in games has influences over the movement of 3-dimensional game character as well as its background. The animation of character has been influenced by animator's level of skill, but it was problematic to have unnatural movement and long-term production time. In this regard, this study will compare the most widely used animation techniques such as Key-Frame method and Motion-Capture method each other and try to figure out which one is the most appropriate and effective method in 3 dimensional game character animation.

대중에게 하나의 취미 생활로 자리매김한 게임은 특징이나 작동 방법에 따라 다양한 장르로 발전되었다. 그 중 액션게임 장르는 사용자가 조작하는 캐릭터의 역동적인 움직임과 움직임이 큰 동작으로 인해 사용자로 하여금 게임 플레이에 몰입할 수 있는 특징을 가지고 있다. 과거 2D 환경의 게임에서 연속되는 그림으로 표현되던 캐릭터의 애니메이션 장면은 3D 환경으로 발전하면서 새로운 애니메이션 기법을 필요로 하였으며, 현재 다양한 애니메이션 기법이 연구되고 있다. 본 논문에서는 3D 뼈대 애니메이션 통하여 DirectX에서의 캐릭터 애니메이션 적용 대해 설명한다.

Distance learning systems that teacher and learner(s) are located at remote have been in progress in a way that directly transfer the video and audio. To get the interest of learners and effectiveness of education or to overcome the poor network environment, various methods utilizing computer graphics in the distance learning system have been attempted. This paper describes a design and implementation of a distance learning system using 3D animation control technology based on Kinect and network game technology. Distance learning system designed and implemented in this paper is a good example of combining education and game technology. And I expect to be used at various educational contents in the future.

Squash & Stretch principle is playing an essential principle for animation action. The application of this principle gives the illusion of weight and volume to an animation character, and makes it possible that an animation action be the smooth and soft by escaping from the stiffness and rigidity. If an action of human or object on animation is expressed like a real world, it seems to be unnatural. Any action without Squash & Stretch will look rigid, uninteresting and not alive. It can be applied to movement of all objects, characters' actions, dialogues and facial expressions with a basic rule of mass, volume and gravity. Any action will not be well expressed without this principle. To be a good animation action, it should be deeply applied in 3D animation, not only 2D animation. Thus, a systemic analysis of Squash & Stretch principle is required.

Recently 3D animation can produce animation dose to real picture owing to rapid technical development of hardware and software and is used as entertainment factors for movie, ads, game and digital pictures. The process of making 3D animation needs the various making techniques and expression factors unlike traditional animation. Production technique and expression factors in making 3D animation are not acted as individual factor, but they can achieve an animation with high perfection when they should be combined. Therefore this study analyzes the technical expression methods based on hardware and software for operation by computer process and the artistic expression factors based on aesthetic, figurative, design and pictorial factors and then seeks a method of making animation with technical perfection.

This study presents a method for capturing photographs of users as input and converting them into 2D character animation sprites using a generative adversarial network-based artificial intelligence network. Traditionally, 2D character animations have been created by manually creating an entire sequence of sprite images, which incurs high development costs. To address this issue, this study proposes a technique that combines motion videos and sample 2D images. In the 2D sprite generation process that uses the proposed technique, a sequence of images is extracted from real-life images captured by the user, and these are combined with character images from within the game. Our research aims to leverage cutting-edge deep learning-based image manipulation techniques, such as the GAN-based motion transfer network (impersonator) and background noise removal (U² -Net), to generate a sequence of animation sprites from a single image. The proposed technique enables the creation of diverse animations and motions just one image. By utilizing these advancements, we focus on enhancing productivity in the game and animation industry through improved efficiency and streamlined production processes. By employing state-of-the-art techniques, our research enables the generation of 2D sprite images with various motions, offering significant potential for boosting productivity and creativity in the industry.

Most designers use professional 3D animation tools such as 3DS MAX to manually create animation. This manual method requires a great deal of time and efforts, and does not allow animation characters to interact with one another. In this paper, we design an AI middleware of form as 3DS MAX plug-in to solve these issues. We present an AI expression structure and internal processing method for this middleware, and the method for creating AI character's structure. It creates AI character's structure by drawing figures and lines for representing AI elements. For experiment, we have produced same animations with the traditional method and our method, and measured the task volume in both methods. This result verifies that the task volume is similar or higher than the traditional method in small-scale tasks, but up to 43% of the task volume is reduced in large-scale tasks. Using the method proposed in this paper, we see that characters in an animation interact each other, and task volume in large-scale tasks are reduced.
