We can choose arbitrary location and direction of cameras to visualize the 3D virtual environment. Constructing a 3D virtual environment needs many models such as, terrain, buildings, vehicles, vegetation, etc. and fluid data such as, atmospheric pressure, temperature, speed, humidity, magnetic field, etc. When a lot of models and complex data are included in a virtual environment, the management of the environmental models and data will be very difficult and very important, so we need a complicated representation and specification to describe the virtual environment. In this study, we provide a synthetic environment system (SEsystem) which is based on the synthetic environment data representation and interchange specification (SEDRIS). The SEDRIS is a software engineering technique for describing a lot of models and complicated data in virtual environments. We use the technique to clearly represent 3D models and their properties to build a virtual environment. We emphasize the structure of property in SEDRIS; we describe methods to set properties into models, and offer an importer for file transformation between SEDRIS and the other file formats.
