The rapid development in computer technology has led to remarkable development in the field of VFX that used in making real picture film. In the past, it was very hard work to make the VFX scenes by means of analogue ways. But these days, CG Animation technology has them make rapid progress and dazzle with brilliance. Recently we can judge the most advanced technology and IT technology based on CG technology introduced in VFX. VFX on CG technology becomes the concentration and the symbol of the most advanced technology. I study manufacturing movement of VFX on CG technology. It shows manufacturing tools are subdivided and the interface is convenient to use, so that artists have applied analogue manufacturing technology easily. The improvement of the computer has made it possible to develop CG technology and tools for hyper-realism. Industries and laboratories in the country get excellent result but we have to concentrate on people in this field more. First of all, we get out of technology copy of Hollywood and we have to develop creative and leading tools reflecting the artists' idea. industry.

Before the appearance of luc-media image, art is performed by the hands of man. That was the best of the reality and the absolute standard of reality. However the appearance of luc-media image brings together the scientific thoughts on realism, which gave birth to 'impressionism' where 'light' becomes the most important part in art as well as in luc-media image and analyzed scientifically. In this paper, I'd like to analyze 5 paintings of Monet, a representative of the impressionism, chronically and present the various aspects of luc-media image as follows; 'picture the present moment', 'picture the light', 'picture the sound and movement', 'picture in the several frames', 'picture continuous frames'. These image phenomenon presented in this paper are mainly concerned with the photograph image, because the time when impressionists entered the stage was the age of photograph image, accordingly there are a little difference from digital image.

A virtual science experience space(VSES) using virtual reality technology including haptic device is proposed to overcome limits which the existing science education has and to improve the effect of it. Four example scientific worlds such as Micro World, Friction World, Electromechanical World and Macro World are demonstrated by the developed VSES. Van der Waals forces in Micro World and Stick-Slip friction in Friction World, the principle of induction motor and power generator in Electromechanical World and Coriolis acceleration that is brought about by relative motion on the rotating coordinate are modeled mathematically based on physical principles. Emulation methods for haptic interface are suggested. The proposed VSES consists of haptic device, HMD or Crystal Eyes and a digital computer with stereoscopic graphics and GUI. The proposed system is believed to increase the realism and immersion for user.

Business utilization of holograms is widely used as a similar hologram. The use of holograms has been proposed in many cases. In this paper, we present an outline of similar holograms using up to 3 or 4 facets, and express the similar holograms using the results produced by 3D modeling for a building from dealing with the representation of buildings from hololens to pseudo-hologram by using 3D modeling results. In addition, to reflect the real image of the disadvantage of modeling, we propose a method to enhance the 3D expression of the object by reflecting the actual building surface on the 3D model through photographing. Virtual building seen by the human eye can be virtually shown in space through a hologram among various methods shown in a virtual space such as AR / VR / MR. Through this study, it will be possible to express holograms of various materials such as buildings or cultural properties with enhanced realism.

As Head-Mounted Displays(HMDs), which are mainly used to maximize realism in games and videos, have experienced increased demand and expanded scope of use in education and training, there is growing interest in methods to enhance the performance of conventional HMDs. In this study, a methodology to utilize Carbon NanoTubes(CNTs) to improve the performance of gate drivers that send control signals to each pixel circuit of the HMD is discussed. This paper proposes a new circuit design method that replaces the transistors constituting the buffer part of the conventional gate driver with transistors incorporating CNTs and compare the performance of the suggested gate drive with that of a gate driver comprising only conventional transistors via simulations. According to the simulation results, by including CNTs in the gate driver, the output voltage can be increased by approximately 0.3V compared to the conventional gate driver high voltage(1.1V) at a speed of 12.5 GHz and the gate width also can be reduced by up to 20 times.

Augmented Reality (AR) is a mix of the real world that is enhanced by virtual objects from computer-generated information. AR is currently used in a variety of information systems and library services. AR technologies are also being developed for today's children, who are digital natives and are exposed to various technologies even earlier. To assist librarians who need to accurately understand users' information needs and perceptions of the technology being used in their libraries, we conducted a study of AR perceptions among children. We conducted two online co-design sessions using "Would you rather?", a co-design technique that facilitates research into children's opinions. Through the co-design sessions, we found that children were psychologically wary about AR technology due to a lack of trust in the technology, and realism had a significant impact on these judgments. We also identified that children considered AR technology environments as an extension of the real world. Their real-world values directly influenced their perceptions of AR. This research provides insights into the wariness that libraries need to be aware of when developing AR content for children in the future, and how libraries can use AR as an educational tool.

Recently, the historical displeasure of celebrities caused a problem that the people were scolded by the people. On the other hand, people's historical consciousness is rising for a series of broadcasts organized by a famous entertainment program. We are now in the idea of our country people like this in history when history will not be left unsaid thing about realism. Inmates because there is a powerful force that is, that media is the 'immersion' players are interested more in the game, it is important to do it. Therefore, the history of games are made based on players to attract attention and interest or historical fact and to make a feature of the game and character.Does not occur to production. So correct history can have a sense of history the players are in fact this study, based on the development called an 'the mythology of the millennium' in 'hq team', manufactured. Choose the game. Scenario is based on thorough historical facts of the game 'the mythology of the millennium' authority order to conduct verification of the historians made it. These production process to appear in the game 'King Gwanggaeto,', 'Geunchogo of Baekje' and 'muyeorwang' design and comparative analysis to the historical facts.

Recently, there is more and more demand on broadcasting display environment that provides a sense of realism basically with high quality and high definition as in UHDTV, so various kinds of 4K cameras have been released. Super 35mm sensor 4K/UHD cameras being generally used can be usefully applied to the single camera-based system such as advertisements, dramas, nature documentaries, and culture programs. However, in the multicamera-based system such as entertaining programs, sports, and concerts, relay broadcasting may face limitations as there are restrictions of close-up or tight shots according to the distance. Besides, 4K lenses are not enough compared with the previous HD lenses' group, so there are limitations in camera photographing shots that have been realized in HD filming. Therefore, to complement this, the use of 2/3 inch sensor 4K/UHD cameras is being demanded, and it is also needed to use various lenses' groups to produce UHD image contents. Accordingly, this study used Grass Valley's LDX 4K/UHD camera to analyze its applicability based on the picture quality test at the use of HD lenses in 2/3 sensors and also the possibility of its efficient application.

This study confirmed the perceptions of performing arts field workers and related experts under the theme of non-face-to-face performing arts. As a result of the analysis, first, respondents agreed with the practical need for non-face-to-face performing arts, but respondents in the field viewed the lack of "fieldability" and "communication with the audience" of non-face-to-face performances as a problem. Second, respondents who participated in non-face-to-face performance production had negative perceptions of realism, immersion, interaction with the audience, lack of enjoyment outside the performance, and difficulties in securing budgets, filming and editing, and actors' acting commitment. Third, regarding the government's non-face-to-face performing arts-related support policy, they complained that support was only given to specific organizations and a small number of people, and administrative difficulties in support. Through this study, it can be suggested that face-to-face and non-face-to-face performance arts should be treated in a complementary and balanced relationship in terms of government policy.
