Use JAVA 3D To Realize The Study Of The Technology Of The Building 3D Scene By Mutual Way

With the development of the net technology and the 3D technology of computer, virtual reality has been used at large. Author choose graphics tool JAVA 3D to study and discuss the building 3D scene by mutual way after comparing several graphics tools, and designed a 3D constructing software by facing object way aim at provided operation of fire protection sectional. This software can make user build 3D high layer architecture and big architecture frequently and add fireproofmg sign and scattered doors sign and save it by convenient operation. User can open scene that has been saved by scene file and modify it. This software can reappear structure inside of high layer architecture and big architecture. It can do some fire protection inspection at peacetime and command in locale when fire is occurring, So this problem has great actual meaning.Working in this thesis apply fire protection file. The speed of building 3D scene is a very important factor except full information in relation to fire protection and full function.In mutual operation way, author advanced a way from 2D plan to 3D scene picture by comparing several mutual interface in common use and combining material application in fire protection. User can operate it and build needed scene and add fireproofing sign and scattered doors sign in the scene expediently and frequently by this way.Modification is very important to graphics software. The emphasis of the software is building high layer architecture, so we can build it neatly no other than integrate function of modification. By this data structure designed user can modify every layer, delete architecture unit protracted, transform coordinate of architecture unit and transfer , rotate , zoom one or several architecture unit at the same time.Author used perdure data technology in saving scene, concretely, saved all objects in relate to scene into object file defined by user by object serial file technology provided by JAVAlanguage. To resume scene, getting all object saved in file orderly and evaluate it to correlative object in program when open scene file next time.This problem has some extensive academic value and actual value, its applied foreground has been recognized by Police Ministry Shenyang Fire Protection Science Graduate School. This problem is on further development.
