This study describes a construction procedure of 3D virtual space using the NGIS data and its application to simulation. 3D space topography is modeled by using DEM consisted with triangular regular network. The elevations of nodal points of DEM are calculated through the interpolation with contour line and elevation points from the NGIS. Also, data for 2D roads and their environments, such as trees, lamps, and traffic signals, were extracted from the NGIS and projected on the DEM surfaces to get 3D virtual space. To give a reality to 3D virtual space and accelerate its graphic speed, data were converted into the directX format. It is believed that the virtual space constructed in this work can be applicable to the ubiqutous because DEM data can be converted to the AutoCAD format and ASCII code.

With the increasing popularity of computer-generated virtual influencers, the trend is rising especially on social media. Famous virtual influencer characters Lil Miquela and Imma were all created by CGI graphics workflows. The process is typically a linear affair. Iteration is challenging and costly. Development efforts are frequently siloed off from one another. Moreover, it does not provide a real-time interactive experience. In the previous study, a real-time graphic workflow was proposed for the Digital Actor Hologram project while the output graphic quality is less than the results obtained from the CGI graphic workflow. Therefore, a real-time engine graphic workflow for Virtual Influencers is proposed in this paper to facilitate the creation of real-time interactive functions and realistic graphic quality. The real-time graphic workflow is obtained from four processes: Facial Modeling, Facial Texture, Material Shader, and Look-Development. The analysis of performance with real-time graphical workflow for Digital Actor Hologram demonstrates the usefulness of this research result. Our research will be efficient in producing virtual influencers.

Digital twin is a technology that creates a virtual space that replicates the real world and manages the real world efficiently by integrating the real and virtual spaces. The digital twin concept for water facilities is to effectively manage water pipes in the real world by implementing them in a virtual space and augmenting them to the interior space of the building. In the proposed method, the Unity 3D game engine is used to implement the application of digital twin technology in the interior of a building. The AR Foundation toolkit based on ARCore is used as the augmented reality technology for our Digital Twin implementation. In digital twin applications, it is essential to match the real and virtual worlds. In the proposed method, 2D image markers are used to match the real and virtual worlds. The Unity shader program is also applied to make the augmented objects visually realistic. The implementation results show that the proposed method is simple but accurate in placing water pipes in real space, and visually effective in representing water pipes on the wall.

When digital media and images are combined, their significant sociocultural impacts can be exercised. Therefore, this study analyzes digital images shown in such trends of digital media compared to the digital fashion from an aesthetic perspective. Research and empirical studies are focused upon to analyze the aesthetic characteristics of digital fashion. Digital Fashion comprehensively refers to fashion design using computers and software, and is considered as "Fashion Design utilizing Digital Technologies" including computer software and hardware perspectives, so that it may be renamed "Digital Fashion." The esthetic characteristics shown in the Digital Fashion defined above are analyzed according to how media philosophers conceptualize the digital image. First, from the perspective of creation, Digital Fashion Images are technical images produced by computers. Uncanny characteristics expressed through virtual images look more realistic than the actual ones used in experimental works of fashion designers. Such virtuality dynamically expresses various colors and fabric patterns through lights using digital technologies that do not yet exist in cloth form, rather in a non-material form of dynamic virtual imagery. Digital fashion images on monitors express digital fashion designs by shaping virtual images through 3D printing. Second, Digital Fashion Images from the perspective of acceptance are created through deconstruction, while fashion has only been previous viewed visually, Digital Fashion delivers immersions of visual touches as if directly experienced for accepters. Digital Fashion will continuously develop and become more influential as it converges with digital media.
