In this paper, we developed a Widows 98 version off-line programming system which can simulate a track vehicle model in 3D graphics space. The track vehicle was adopted as an objective model. The interface between users and the off-line program system in the Widows 98's graphic user interface environment was also studied. The developing language is Microsoft Visual C++. Graphic libraries, OpenGL, by Silicon Graphics, Inc. were utilized for 3D Graphics.

This study is aimed at developing the structural design interface module for the brace connections in order to improve the efficiency of the interoperability between structural design and BIM modeling at the construction design phase of steel structures. For this purpose, structural design module is first established according to the algorithm built by structural design standards of domestic and foreign. Then, it is developed interface module which can export the data of 3D model obtained from the BIM design tools to structural design module and feed structural design results back to 3D BIM model. Finally, the efficiency and practicality of the developed interface module is verified by applying to a sample model.

The facial modeling and animation technology had been studied in computer graphics field. The facial modeling technology is utilized much in virtual reality research purpose of MPEG-4 and so on and movie, advertisement, industry field of game and so on. Therefore, the development of 3D facial model that can do interaction with human is essential to little more realistic interface. We developed realistic and convenient 3D facial modeling system that using a optional facial image only. This system allows easily fitting to optional facial image by using the Korean standard facial model (generic model). So it generates intuitively 3D facial model as controling control points elastically after fitting control points on the generic model wire to the optional facial image. We can confirm and modify the 3D facial model by movement, magnify, reduce and turning. We experimented with 30 facial images of $630{\times}630$ sizes to verify usefulness of system that developed.

The design methodology of injection molding die has been changed from two-dimensional drafting to three-dimensional solid modeling, which is due to many advantages over the conventional methodology in terms of design modification and data associativity. In addition to the solid modeling capability, it is required for a mold designer to utilize a database management system that facilitates efficient mold design. In the paper presented is the implementation of a software program which automatically generates three-dimensional mold-bases including standard parts and slider parts, conforming to given geometric constraints. It is based on a commercial CAD system (Unigraphics NX) along with related API (application program interface) libraries. The research is expected to reduce design efforts and simplify construction of a complex three-dimensional mold-base model that is comprised of standard parts and slider parts, by use of the three-dimensional database and automatized geometric dimensioning.

As IT-based technologies develop, 3D GIS applications that digitally model real environment are being increased. Although the terms related with 3D CIS are used increasingly, research efforts and applications are mostly limited to only 2D GIS or 3D modeling respectively. The reasons are viewed that there have been less research findings or software tools about integration of 2D GIS and 3B models. Thus, this study presents a method to integrate 2D GIS and 3D models by using database as the means for linkage. To illustrate the process, we developed a prototype application using C# language. Within an interface we showed how to integrate different libraries - EON Studio and MapObjects. We expect that the integration techniques we suggest here can be applied to such areas as disaster prevention, transportation and natural resources management.
