Since the world's first 3D commercial film with red-blue glasses was introduced in 1922, remarkable progress has been made in the field of 3D video. 3D video content gained enormous popularity with the movie "Avatar," which greatly increased the sale of 3D TVs. This momentum has weakened owing to lack of 3D content. However, the recent trend of virtual reality (VR) and augmented reality (AR) made 360 VR video and 3D games using a head mounted display wide spread. All these experiences mentioned above require wearing glasses to enjoy 3D content. Super multi-view content technology, on the other hand, enables viewers to enjoy 3D content without glasses on a super multi-view display. In this article, we introduce the technologies used to make super multi-view content, interact with it, and author content, which are developed by ETRI.

In this paper, we describe reconstructed 3D-urban modeling techniques for laser scanner and CCD camera system, which are loading on the vehicle. We use two laser scanners, the one is horizon scanner and the other is vertical scanner. Horizon scanner acquires the horizon data of building for localization. Vertical scan data are main information for constructing a building. We compared extraction of edge aerial image with laser scan data. This method is able to correct the cumulative error of self-localization. Then we remove obstacles of 3D-reconstructed building. Real-texture information that is acquired with CCD camera is mapped by 3D-depth information. 3D building of urban is reconstructed to 3D-virtual world. These techniques apply to city plan. 3D-environment game. movie background. unmanned-patrol etc.

With the development of 3D technology, image expression has been widely used in the field of 3D animation these days for the purpose of illustrating a certain image, feeling or status. In this paper, we examine how it affects to audiences' feelings and senses when we applied the handheld camera technique to other kinetic characteristics. In addition, we analyze the scenes which the handheld camera technique is applied into each characteristic from movie contents, present the kinetic characteristics of the handheld camera technique, and study the scenes that can apply this technique with 3D animation and its influence.

본 연구는 서울시 25개 구, 354개의 스크린 수를 이용하여 영화상영관의 입지 패턴은 지역의 공간적인 연계성에 의해서 입지함을 GIS를 이용한 공간파급력 비교와 공간회귀모형을 이용한 공간결정요인을 이용하여 도출하였다. 스크린 수를 분석의 Z값으로 설정하여 영화상영관의 공간파급력을 분석한 결과, 서울의 영화상영관은 강북, 강남, 강서, 강동 4개 지역을 중심으로 영향력이 생성되는 것으로 분석되었으며, 4개 주요 중심축의 영향력 파급 결과, 상대적으로 영화상영관 스크린 수가 많은 지역의 파급력은 평면적으로 넓게 파급되기보다는 지역 내에서 높게 영향력이 생성되는 것을 보여 주변 인구가 영화상영관이 있는 지역으로 이동하여 영화매체를 관람하는 것으로 분석되었다. 영화상영관의 스크린 수에 직접적으로 영향을 미치는 공간적인 결정요인을 공간회귀모형을 이용하여 분석한 결과, 출판, 음반, 공연 관련 업체가 많을수록 영화상영관의 스크린수가 증가하는 것으로 나타났다.

The global movie industry is continuing rapid growth through application of the latest technology. 3D movies are being produced and shown for a more effective viewing experience. Special chairs for audiences are being experimentally manufactured and installed for the greatest viewing effect. This special chair has a structure that applies vibrating stimuli to specific parts of the body by attaching vibration transducers to theater chairs and synchronizing it with each scene of the movie. In a previous study, it has been confirmed that we can analyze the vibration transfer characteristics of sponge seats through the application of an experimental modal analysis method and obtain design variables easily. In this paper, we examine the major design parameters needed in the development of a foaming sponge seat in which auxiliary springs are inserted to improve the vibration transfer effect of a chair seat. Through analyzing several prototypes by applying experimentation as well as the experimental modal analysis method, it was confirmed that the effect of vibration transfer can be improved through the use of an auxiliary member.

영화 아바타가 세계적으로 큰 성공을 거두면서, 대중들의 3D입체영상에 대한 관심은 증폭되었다. 그러나 일반적으로 3D라 일컬어지는 stereoscopic에 대한 대중들의 폭발적인 관심이 얼마나 지속될 수 있을지는 미지수다. 소비자들은 사회문화 환경 변인에서 오는 그들의 누적된 경험과 지배적인 의식이 있다는 점을 고려해야 할 것이다. 따라서 같은 내용의 영상물을 2D와 3D 입체영상으로 제시했을 때, 몰입도나 흥미의 지속성 등의 차원에서 어떤 차이를 보이는가에 대해 알아보는 일은 중요하다. 이 같은 관점에서, Jennett (2008) 은 게임의 몰입에 관한 측정도구를 개발하였는데, 본 논문에서는 이 도구를 이용하여, PC 게임 사용자들이 느끼는 3D 입체영상과 2D에서 몰입과 흥미 등의 정도 차이를 알아보고자 하였다.

The 3-D shape use to effect of movie, animation, industrial design, medical treatment service, education, engineering etc... But it is not easy to make 3-D shape from the information of 2-D image. There are two methods in restoring 3-D video image through 2-D image; First the method of using a laser; Second, the method of acquiring 3-D image through stereo vision. Instead of doing two methods with many difficulties, I study the method of simple 3-D image in this research paper. We present here a simple and efficient method, called direct calibration, which does not require any equations at all. The direct calibration procedure builds a lookup table(LUT) linking image and 3-D coordinates by a real 3-D triangulation system. The LUT is built by measuring the image coordinates of a grid of known 3-D points, and recording both image and world coordinates for each point; the depth values of all other visible points are obtained by interpolation.

This paper proposes a reconstruction method for the shape and color information of 3-dimensional buildings. The proposed method is range scanning by laser range finder and image coordinates' color information mapping to laser coordinate by a fixed CCD camera on laser range finder. And we make a 'Far-View' using high-resolution satellite image. The 'Far-View' is created that the height of building using DEM after contours of building extraction. The user select a region of 'Far View' and then, appear detailed 3D-reconstruction of building The outcomes apply to city plan, 3D-environment game and movie background etc.

The production and authoring of digital multimedia contents are most important fields in multimedia technology. Nowadays web-based technology and related multimedia software technology are growing in the IT industry and these technologies are evolving most rapidly in our life. The technology of digital audio and video processing is utilizing rapidly to improve quality of our life, Also we are more interested in high sense and artistic feeling in the music and entertainment areas by use of three dimensional (3D) digital sound technology continuously as well as 3D digital video technology. The service field of digital audio contents is increasing rapidly through the Internet. And the society of Internet users wants the audio contents service with better quality. Recently Internet users are not satisfying the sound quality with 2 channels stereo but seeking the high quality of sound with 5,] channels such as 3D audio of the movie films. But it might be needed proper hardware equipments for the service of 3D sound to satisfy this demand. In this paper, we expand the simple 3D audio generator developed and propose a web-based music bank by the software development of 3D audio generation player in 3D sound environment with two speakers minimizing hardware equipments, Also we believe that this study would contribute greatly to digital 3D sound service of high quality for music and entertainment mania.

최근 3D 애니메이션은 급속한 하드웨어와 소프트웨어의 기술적 발전에 힘입어 실사에 가까운 애니메이션 연출이 가능하게 되어 영화, 광고, 게임, 디지털 영상물 등의 엔터테인먼트적인 요소로 많이 사용되고 있다. 3D 애니메이션 제작과정은 전통적인 애니메이션과는 달리 다양한 제작기술과 표현요소를 요하게 된다. 3D 애니메이션 제작에서 제작기술과 표현요소는 각각의 요소로 작용하는 것이 아니라, 서로 결합하여 제작하여야만 완성도가 높은 애니메이션을 얻을 수가 있다. 이에 본 고는 3D 애니메이션 Computer Process에 의한 작업 과정을 하드웨어와 소프트웨어를 바탕으로 한 기술적인 표현방식과 미학적, 조형적, 디자인적, 회화적 요소를 바탕으로 한 예술적 표현요소를 분석하고 기술적인 완성도와 표현력이 있는 애니메이션을 제작하는 방법을 모색해 본다.
