영화 속 공간에 나타난 고대 그리스 건축의 특성 비교분석

This study set out to make a list of movies that used the architectural styles of ancient Greece and their related sets and locations and compare and analyze them. The ultimate purpose was to identify the characteristics of space in movies to make use of them in education about the history of Greek architecture. The methods adopted in the study were as follows: first, the study had a general examination into the architectural styles of ancient Greece, categorized movies set in the Greek period, and made a list of them. Second, the results were used to identify the spaces of ancient Greek architecture in each of the movies and the characteristics of their styles. Third, these were compared and analyzed to figure out the characteristics of their flows and select their representative movies. The findings were as follows: first, there was a trend of detailed expressions of backgrounds in movies based on the application of framing shooting for angles of depression in case of Greek architecture whose historical research had been enough in the history of architecture. Second, many movies set in Greece repeatedly reproduced certain buildings that tended to be more complete in proportion and form. Third, `Troy` is the most creative film in terms of visuality through effective combination of large-scale set-up era and CG technology. Finally, “300` and “300: Rise of an Empire`, which are representative of the middle Greek period, can be seen as a case of demonstrating that CG is a very advantageous technique for applying architectural historical characteristics to the set space in the film.

Discussion and Analysis on Television Packaging and Title Font Design in China

Integral Photography Using 2D Printer Output and Fly's Eye Lens Made with 3D Printer

A new integral photography (IP) technique is presented in which printing technology is used to make not only an IP image but also a fly's eye lens. IP is one of the best methods for 3D displays because both horizontal and vertical parallax can be obtained without having to wear special glasses. A fly's eye lens, which integrates a large number of small convex lenses in array form, is the key component of IP. However, such lenses had to be purchased from a limited number of commercially available options since using a metal mold to custom make them was extremely costly. This situation changed substantially with the emergence of a 3D printer that could produce highly precise and transparent lenses easily and inexpensively. We therefore used our original software to model a fly's eye lens that comprised many minute spherical lenses as a triangular mesh. The resulting STereoLithography (STL) file was then transferred to a 3D printer and a fly's eye lens was made. We also used our conventional CG technology to synthesize an IP image that integrates images observed from many viewpoints. When the image was printed with a full-color inkjet printer and the fly's eye lens was put on it, an excellent 3D image was obtained.

Hair image generating algorithm using fractional hair model

In the field of multimedia communication and very low bit-rate communication, it is necessary to generate natural and synthetic images by computer. CG technology plays an important part in realizing the communication. Using a realistic human model by CG technology, we can construct a new man-machine interface which is easy to use. Moreover, using a CG image can reduce the quantity of communication data compared with a video image data. The reduction of communication data enables very low bit-rate communication and real-time communication. Recently, many kinds of objects have become realistically generated using CG technology because CG technology has rapidly improved. However, human hair remains to be one of the most difficult objects to generate easily because the number of hair is enormous and the hair size has very thin figure. Furthermore, the style is very different individually and easily changeable by external force. In this paper, a new hair model named ‘fractional hair model’ is proposed to reduce the total quantity of the hair data and many human hair CG images generated by this model are also presented.
