  • Recently, as the public interests about the 3D printing technology are increased, various kinds of 3D printers are being released. But, they are limited to use because they cannot fabricate an object which is larger than the printer's printing volume. To relieve this problem, we propose an interactive 3D mesh editing system for 3D printing the object that is larger than the printing volume. The proposed 3D editing system divides the input 3D mesh using the user's line drawings defining cutting planes and it attaches various connectors. The output meshes are guaranteed to fabricate without post-processing. The printed parts can be assembled using the connectors. Our proposed system has an advantage that it can be used easily by non-professional 3D printer users.

  • 3D 입체영상은 영화관에서 시작되어 최근에는 방송, 게임, 테마파크에 이르기 까지 널리 확산되고 있다. 하지만 3D 입체영상에 대한 응용기술의 발전은 입체영상에 쉽게 접근하게 하였음에도 불구하고 3D 입체영상을 시청하는 사용자에 대한 근본적인 연구가 미흡한 실정이다. 이러한 문제로 인하여 3D 입체영상을 접한 대부분의 시청자들이 안구통증, 어지러움 증을 호소하지만 이에 대한 근본적인 대책을 제시하지 못하는 것이 현실이다. 따라서 이러한 입체피로를 해결하기 위한 3D Sweetenig을 다양한 연구방법으로 진행되고 있고, 그 중 4D 체감형 콘텐츠에 대한 감성연구실험 절차를 소개하고자 한다.

  • A big success of the 3D film 'Avatar' in 2009 opened a full-fledged 3D movie era. A new industrial possibility of 3D contents was predicted in Korea and then the support for 3D contents production took placed via various media platforms. Korean government also announced the new development policies with a focus on 3D content. However, the 3D content industry has not been activated. Therefore, in this study by applying AHP(Analytic Hierarchy Process) method we tried to grasp the reason of the deactivation of 3D content industry through analyzing the relative importance rate of three research factors(content aspects, technical aspects, and policy aspects) that were mainly considered to activate the industry. The results of this study showed that the relative importance rate of content aspects was higher than that of technical aspects and policy aspects. It means the lack of 3D contents is one of main reason causing the delay of 3D industrial activation. And it also showed that the relief of human factors such as visual fatigue evaluated as a sub-factors of technical aspects are challenges to be solved soon..

  • This research entailed the production of stereoscopic 3D (S3D) contents using 2D-to-S3D conversion for exhibition at a museum and subjective evaluation. Hybrid production combining S3D images of existing live-action videos using the 2D-to-S3D conversion technology and computer graphic ones created via stereo rendering was conducted. Design and control of the chronological analysis of the parallactic angle was conducted on the produced contents, using binocular information as well as subjective evaluations, with the intent of conducting an investigation on the characteristics of such contents from the perspectives of the producers and viewers. An investigation was also conducted on the effects of the viewing position on the impressions of the S3D images.

  • In this paper we proposed web-based educational multimedia contents development method using Web 3D technology and implemented web 3D contents for use at the education field. A implementation of contents is composed of modeling to specific entity in 3D shape, convert modeling data to enable data at web and include in webpage. A practical use of contents on this research can provide more advanced user experience and immersion.

  • There is little study related to the 3D convergence contents authoring tool for teacher. In this study, we purposed the design of the interactive 3D convergence contents authoring tool for a teacher. To draw the design, firstly, we investigated the authoring environment of teachers and interviewed teachers. Based on this investigations, we proposed the functional requirement and UI/UX(User Interface/User Experience) design of it. And we investigated the level of focusing group satisfication with the UI/UX design. Based on these results, we will implement the authoring tool.

  • Recently, the interest of 3D contents are increased and viewers demand a variety of 3D contents. In such circumstances, underwater 3D contents are an alternative to meet the demands of viewers. Cause that underwater mass density is 1.33 times that in air the objects in underwater is bigger and closer in real. Therefore it needs to modify the distance between cameras, the distance to objects and the convergence value. In this paper, we present the method to set optimal depth values with the particularities of underwater space. In addition, through the case of underwater 3D production we present the method of underwater 3D contents development. We expect that a lot of material with colorful, variety marine organism in underwater will be made of 3D contents.

  • The 3D contents are getting more attentions in various areas, such as in movies, advertising, games and exhibition contents. There are many authoring tools for making 3D Models and contents. However, those authoring tools take considerable amount of time to learn and to make 3D contents. In this paper, we propose the 3D model conversion algorithm to make 3D models from 2D pictures drawn on the touch screens or papers. The vertex animation method also proposed for the interactive 3D aquarium. The proposed vertex animation algorithm was tested for virtual 3D water creatures and compared with human-made animation. An Interactive 3D aquarium was implemented by using those proposed algorithms. Thus the simplicity and effectiveness of the algorithms can be applied to diverse industries.
