디지털 기술의 발전에 따라 메타버스가 콘텐츠 시장의 주요 트렌드로 자리하면서 고품질의 3D(dimension) 모델을 생성하는 기술에 대한 수요가 급증하고 있다. 이에 따라 디지털 휴먼으로 대표되는 고품질 3D 가상 인간의 제작과 관련된 다양한 기술적 시도가 이루어지고 있다. 3D 볼류메트릭 캡처는 기존의 3D 모델 생성 방식보다 빠르고 정밀한 3D 인체모형을 생성할 수 있는 기술로 각광 받고 있다. 본 연구에서는 볼류메트릭 3D 및 4D 모델 생성 분야에서 적용되는 기술들과 콘텐츠 제작의 애로사항에 대해 실제 사례를 바탕으로 3D 고정밀 페이셜 제작 기술의 분석을 시도한다. 그리고 실제 볼류메트릭 캡처를 통한 모델의 구현 사례를 바탕으로 3D 가상인간의 얼굴 제작에 대한 기술들을 고찰하고 효율적인 휴먼 페이셜 생성을 위한 그래픽스 파이프라인을 활용하여 새로운 메타휴먼을 제작하였다.

Recently, case presentations using AI functions such as ChatGPT are increasing in many industrial fields. As AI-based results emerge even in the areas of images and videos, traditional animation production tools are in need of significant changes. Unreal Engine is the tool that adapts most quickly to these changes, proposing a new animation production workflow by integrating tools such as Metahuman and Marvelous Designer. Working with realistic metahumans allows for the production of realistic and natural movements, such as those captured through motion capture data. Implementing this approach presents many challenges for production tools that adhere to traditional methods. In this study, we investigated the differences between the cell animation workflow and the computer graphics animation production workflow. We compared and analyzed whether these differences could be reduced by creating sample movements using character rigs in Maya and Cascadeur tools. Our results showed that a similar cell animation workflow could be constructed using the Cascadeur tool. To improve the accuracy of our conclusions, we created large, action-packed short animations to demonstrate and validate our findings.

With the development of digital content software production technology and the technological progress of related hardware, the social status quo in the post-epidemic era, the popularization and application of 5G networks, the market and consumers' increasing demand for digital content products, artificial intelligence, virtual digital human, virtual Idols, virtual live, self-media content and metaverse-related content industries are all developing rapidly. Virtual idols, virtual digital human, etc. are not only accelerating innovation in production technology. The economic cost, technical difficulty and time requirements of production are also greatly reduced. With the arrival and development of the Metaverse, the author believes that the content industry with virtual digital humans as the core will continue to develop in the direction of refinement, specialization, facilitation and customization. In this article, we will analyze and study the production of virtual digital human based on Photoscan technology and Unreal Engine 5 Metahuman software, and discuss the application status and future development of related content.

This thesis is a study of content development utilizing media outlets to date through digital humans. The trend of global content is that the video content industry, including the character business, is growing. Lil Michela, who was selected as one of the 25 most influential people on the Internet by Time magazine in 2018, Nasua, who appeared in a SK Telecom commercial, and Rosie, who appeared in a Shinhan Bank commercial, are representative. Digital humans, which are driving new content, are computer-generated human characters with various characteristics and are referred to as virtual humans, metahumans, and cyber humans. With the rise of the metaverse after COVID-19, digital humans are being utilized in various forms such as media and marketing as an element of visual content. In the form of media, we can see that the boundaries between the offline and digital worlds are converging, and in the form of marketing, we can see that digital humans connect consumers and products more naturally. In the form of interaction, it is possible to achieve two-way communication through various methods of operation, and through these factors, it is possible to go beyond behavioral communication in the form of memorialization to emotional communication through AI technology. What can be seen through these processes is that through the currently developing digital human production methods and AI functions, not only experts but also non-experts can create quality contents, and new directions of contents will appear, and contents that can provide immediate feedback by bringing consumers and creators closer together have been studied.
