Interactive real-time 3D enables users to explore virtual three dimensional environments and also experience contents in an absorbing fashion. Unlike other media, Interactive real-time 3D users take an active role in the process of "real-time fashion" where action and reaction occur instantly in a digital 3D structure. Once the components and origins of interactive real-time 3D is made, it is possible making principles of the beauty that help decide success or failure of real-time 3D in two way system. Substantial real-time 3D has not yet passed 10 years so it was unable to make sufficient precedents of fundamental artistic value based upon the credibility of the media. The goal is to explain the new form of design in relation to general principles of arts at the same time to understand the technical definition better. Concepts of historical documentation are explained with an example of categorization of recent video game and recent technology. This thesis concludes with rough forecast on the future interactive real time 3D. Since the medium began relatively recently and is developing in the rapid pace, recent analyses, though clear forecast is difficult, tend to investigate potential directions to some level the field allows.

The 2D based-web contents are limited to implement interactive elements for the users even though the contents are offered in various styles. Using the mouse and keyboards users chose any web contents for themselves beyond the limitation of time and space. They want more interactive style as they become familiar with convenience of web contents. The 3 dimensional web contents integrated with interactive technologies are one of the ways for them There are many researches and commercialization of the interactive web 30 for the past years because it has a lot of user benefits in terms of immersion, realistic expression, and interactivity. It has two types of implementation; one is for 3D polygon based objects, the other is for virtual worlds. This research is focus of on the concept of web interactive 3D, the technical aspects, design elements, and the proposal of navigation methods for the purpose of creating new type of web interactive contents.

This study is a VR system design designed to evaluate the impact of interaction on user experience analyzed by developer's perspective for the interactive VR fashion show. In the VR fashion show design, we produced an interactive system through the four interactive elements of camera viewpoint, cloth, effects, and sound. The interactive design system is proposed based on three application facto rs in VR space design: speed, range, and mapping. The study focused on the user experience based on format conversion to apply the Unity3D engine using 3D model, animation, 2D UI design, and simulation.

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.

A prototype computer program was developed which visualizes various kinds of geotechnical information using 3D object graphics techniques. The program integrates various kinds of geotechnical data such as surface geology map, boreholes data, geophysical data as well as man made subsurface structures. It also reads NGIS DXF map and generates digital elevation model from iso-elevation line layer of the DXF map. All the data are put into a 3D model as 3D objects. The created 3D model can be viewed and analysed in a interactive 3D way.

디지털방송의 애플리케이션(Xlet)은 시청자와 방송프로그램간의 상호작용에 중요한 역할을 담당한다. 현재 이러한 애플리케이션 UI는 평면이미지로 구성하는 것이 대부분이며 화면상 영역은 2차원으로 제한된다. 본 논문은 이러한 2차원의 평면적인 느낌을 극복하고 3차원이 가진 다양한 이점을 살리기 위한 3차원 UI구현방법을 제시한다. 이를 위해, 본 논문은 가상의 3D System, Virtual Timeline, Animation Model 등을 구성하였다. 3D System이란 UI가 3차원 좌표계를 가지기 위한 환경을 말하며, Timeline과 Animation Model은 제한적인 성능의STB에서 보다 진보된 애니메이션을 UI에 적용하기 위한 기법이다. 이들은 다양한 애플리케이션 제작, 서비스 개발 등에 응용이 가능하다. 디지털방송은 매우 빠른 속도로 발전하고 있으며 새로운 형태의 서비스가 속속 등장하고 있다. 이러한 흐름에 발맞춰 3D UI는 기존의 TV 화면에서 보다 진보된 형태의 사용자 인터페이스의 모습을 보여줄 것이다.

In this paper, we present an interactive 3D character modeling and animation including a data management tool for editing the animation. It includes an animation editor for changing animation sequences according to the modified structure of 3D object in the object structure editor. The animation tool has the feature that it can produce motion data independently of any modeling tool including our modeling tool. Differently from conventional 3D graphics tools that model objects based on geometrically calculated data, our tool models 3D geometric and animation data by approximating to the real object using 2D image interactively. There are some applications that do not need precise representation, but an easier way to obtain an approximated model looking similar to the real object. Our tool is appropriate for such applications. This paper has focused on the data management for enhancing the automatin and convenience when editing a motion or when mapping a motion to the other character.

디지털 방송은 비디오, 오디오와 더불어 데이터를 전송할 수 있다. 데이터 영역에는 셋톱박스(STB)에서 수행되는 애플리케이션(Xlet)이 포함된다. 디지털 방송은 애플리케이션을 이용해 보다 진보된 인터랙티브 프로그램을 제공할 수 있다. 그러나 이러한 인터렉티브 TV에서 3차원 객체의 활용은 아직 여러 제한사항으로 인해 어려움이 있다. 현재 제정된 DVB-MHP, SCTE-OCAP, ATSC-ACAP 등의 데이터 방송 표준은 3D 객체를 표현하기 위한 구체적인 방법을 기술하지 않고 있다. 또한, 상용셋톱박스에 탑재된 자바 가상 머신(Java Virtual Machine)은 3D 객체를 렌더링(Rendering)하기 위한 API를 제공하지 않고 있다. 그리고 이를 위한 별도의 플러그인(Plug-in)도 제공하지 않는다. 본 논문에서는 Interactive TV에서 3차원 객체를 표현하기 위해 필요한 기본개념과 기술 및 데이터 방송 표준을 분석하고, 이들을 통합하여 polygon 기반의 3D Graphic Engine을 제안한다. 특히, 본 논문에서 제안하는 3D Graphic Engine API는 각각의 표준에서 가용한 공통 API를 기반으로 설계 되었으며, Java Virtual Machine 1.1 환경에서 구동될 수 있도록 구현되었다.

This study suggests a model of experimental visual artworks with interactive art forms in which 2-D paintings are transformed to interactive 3-D animation works. Multimedia programming was employed to evolve objective still paintings to the animation of computer 3-D images with respect to visual ideas derived from visual components in the still painting and to response to the reactions users. The format and technique of the art works are based upon the contents developed by the author and the research materials are selected from the surrealistic paintings of tile world-famous Belgian painter, Rene Magritte. In the present paper, following topics are discussed in detail: a study of various visual cases occurring in transforming still paintings to animation works containing interactive components; a study of 3-D imaging and image processing techniques to transform 2-D paintings to 3-D images; animation techniques for interaction and overall structuring techniques; multimedia programming and user interface.
