| dc.description.abstract | Presenting objects and virtual environment in 3D style is more realistic than in 2D style and users can adjust a suitable viewing position in real-time. To build a virtual environment need to load terrain, buildings, cars, plants, etc., and tune them with proper position, direction, and scale. If there are considerable models in the virtual environment, it will be extraordinary complex to display the environment and models. Thus we need complicated representation and specification to describe the whole virtual environment.
In this study, we purpose a virtual environment editing system based on synthetic environment data representation and interchange specification (SEDRIS). The proposed system provides a friendly user interface, environment editing, level-of-detail modeling, roadmap generation, function of collision detection, and model attribute query. The data specification of SEDRIS is a software engineering technique for unambiguously articulating information about the data as the real world. We utilize the technique to unambiguously represent 3D objects and their attributes to achieve a virtual environment construction; moreover, the data representation provides a possible solution to overcome the problem of converting models with different model formats. | en_US |
