| Former high building's fire control file adopted mostly the mode of ichnography, text and chart. However it is more integrated and intuitional than 2D ichnography does if we use the mode of 3D to represent the high building's structure, fire protection establishment's distributing and evacuated channels. The target of the system is researching and impoldering how to make high building's 3D computer model quickly. The system can cross the operation plat and create 3D scene quickly and mutually and provide the 3D instrument for fire control.The system uses JAVA language as programming tool, it makes use of JAVA 3D graphics exploitation tool to research how to make 3D scene mutually. Author inherits the thought of the antetype system and designs the system again. The following four points are the main contents of the study. The system keeps on taking the manner of using 2D ichnography to build 3D scene that is adopted by the antetype system. Users can edit the structure of a building, add fire control things and indoor objects and confirm observational position in the plan. The system creates 3D scene automatically according to the original observational position provided by users. The system emphasizes the concept of the browser's design based on Java3D and makes use of the conception of view platform in Java3D to rich the function of the 3D browser. The browser not only takes on the function of cruise scene but also makes user inquire about the basic information of an object in the 3D scene directly. Author accomplished the elementary design and realization to make the 2D ichnography of high building's environment so that user can find out the circumambient situation of one building. Because the scene is comparatively complex, author used LOD technique to improve system's capability and mend romance velocity.This studying has been chosen to become a longitudinal problem by Shenyang Science and Technology Institute recently.
