Recently, the use of Unreal Engine for animation production is increasing. In this situation, Unreal Engine's 'MetaHuman Creator' helps make it easier to apply realistic characters to animation. In this regard, we tried to produce animations using 'MetaHuman' and verify the effectiveness and differences from the animation production process using only Maya software. To increase the efficiency of the production process, the animation process was made with Maya software. We tried to import animation data from Unreal Engine and go through the process of making animations, and try to find out if there are any problems. And we tried to compare animations made with realistic 'MetaHuman' characters and animation works using cartoon-type characters. The use of the same camera lens in realistic character animations and cartoon character animations produced based on the same scenario was judged to be the cause of the lack of realistic animation screen composition. The analysis revealed that a different approach from the existing animation camera lens selection is required for the selection of the camera lens in the production of realistic animation.

With the rapid development of 3D animation, MetaHuman is widely used in film production, game development and VR production as a virtual human creation platform.In the animation production of virtual humans, motion capture is usually used.Since different motion capture solutions use different skeletons for motion recording, when the skeleton level of recorded animation data is different from that of MetaHuman, the animation data recorded by motion capture cannot be directly used on MetaHuman. This requires Reorient the skeletons of both.This study explores an efficient skeleton reorientation method that can maintain the accuracy of animation data by reducing the number of bone chains.In the experiment, three skeleton structures, Rokoko, Mixamo and Xsens were used for efficient redirection experiments, to compare and analyze the adaptability of different skeleton structures to the MetaHuman skeleton, and to explore which skeleton structure has the highest compatibility with the MetaHuman skeleton.This research provides an efficient skeleton reorientation idea for the production team of 3D animated video content, which can significantly reduce time costs and improve work efficiency.

현재 극장이나 TV에서 상영되고 있는 애니메이션은 대부분 3D 애니메이션이다. 국내의 애니메이션 또한 많은 수가 3D로 제작되고 있으며, 이러한 3D 애니메이션 제작 업체 수는 매년 증가하고 있다. 또한 많은 애니메이션 관련 인력들이 국내 제작업체에서 다양한 국내외 애니메이션을 제작하고 있다. 이러한 애니메이션 산업에서 제작 인력의 중요성은 날로 높아지고 있다. 그 결과 국내 많은 대학에서는 3D 애니메이션 제작 전문 인력 양성에 노력하고 있다. 본 논문은 국내 3D 애니메이션 교육과정에 대하여 다룬다. 특히 현재 국내 3D 애니메이션 제작자들이 참여한 설문지를 바탕으로 이를 분석한 뒤, 대학에서 창의적인 3D 애니메이션 제작 인력양성에 대하여 논의하고자 한다. 이는 대학에서의 3D 애니메이션 교육이 올바른 3D 애니메이션 제작 인력을 양성하고 이러한 인력이 향후 국내의 3D 애니메이션 산업 발전에 기여하는 방향을 제시하는데 그 목적을 둔다.

A hierarchical motion control system for animation of 3D human character is implemented using the motion database in realtime. The proposed motion control system consists of coordination controller for gait timing and balancing of walking motion, joint servo controller for realistic limb movement, and motion database for goal-directed character animation which makes time-consuming animation relatively easy task. As one example among the various applications of the proposed motion control system. We present a simple virtual reality system in which the motion control system plays a central role in generating realistic motion of virtual human character.

3D 캐릭터 애니메이션은 영화, 광고, 게임, 사이버아이돌 등 다양한 엔터테인먼트 요소로 하여 영상산업에서 중요한 위치를 차지하고 있다. 기술적인 발달로 3D 캐릭터 애니메이션은 다양한 연출과 사실적인 표현이 가능하였지만 인체 해부학적 이해가 없이 캐릭터를 제작한다면 비례와 구조에 맞지 않은 캐릭터가 제작되어 진다. 인체 해부학은 신체구조를 해부학으로 분석하여 캐릭터 모델링 제작에 많은 도움을 주고, 캐릭터 애니메이션을 제작할 때도 신체 움직임이나 얼굴표정을 정밀하게 제작할 수 있는 기본 지식이라 할 수 있다. 이에 본고에서는 인체의 구조와 인체의 비례를 살펴보고 인체 해부학적 이해를 바탕으로 3D 캐릭터 모델링과 애니메이션 제작방법에 중점을 두었다.

Real human digital models appear more and more frequently in VR/AR application scenarios, in which real-time markerless face capture animation of personalized virtual human faces is an important research topic. The traditional way to achieve personalized real human facial animation requires multiple mature animation staff, and in practice, the complex process and difficult technology may bring obstacles to inexperienced users. This paper proposes a new process to solve this kind of work, which has the advantages of low cost and less time than the traditional production method. For the personalized real human face model obtained by 3D reconstruction technology, first, use R3ds Wrap to topology the model, then use Avatary to make 52 Blend-Shape model files suitable for AR-Kit, and finally realize real-time markerless face capture 3D real human on the UE4 platform facial motion capture, this study makes rational use of the advantages of software and proposes a more efficient workflow for real-time markerless facial motion capture of personalized 3D real human models, The process ideas proposed in this paper can be helpful for other scholars who study this kind of work.

In this paper, we propose a method for implementing a system for decoding the parameter data based on Facial Animation Parameter (FAP) developed by MPEG-4 Synthetic/Natural Hybrid Coding (SNHC) subcommittee. The data is displayed according to FAP with human mucle model animation engine. Proposed model has the basic properties of the human skin specified by be energy funtional for realistic facial animation.

In recent years, as computer-generated imagery has been applied to more industries, realistic facial animation is one of the important research topics. The current solution for realistic facial animation is to create realistic rendered 3D characters, but the 3D characters created by traditional methods are always different from the actual characters and require high cost in terms of staff and time. Deepfake technology can achieve the effect of realistic faces and replicate facial animation. The facial details and animations are automatically done by the computer after the AI model is trained, and the AI model can be reused, thus reducing the human and time costs of realistic face animation. In addition, this study summarizes the way human face information is captured and proposes a new workflow for video to image conversion and demonstrates that the new work scheme can obtain higher quality images and exchange effects by evaluating the quality of No Reference Image Quality Assessment.

In this paper, we propose a 3-D animation system to track and analyze motion of the human object. The proposed system consists of two separate layers: motion analysis layer and 3-D model registration layer. Following the MPEG-4 SNHC standard, we generate object motion using body definition and animation parameters. In the implemented system, we acquire human motion data from a single camera and extract body definition parameters from arbitrary VRML human models.
