Dynamic dragging and constructing module system with 3D virtual element for on-line exhibition

Abstract

The invention relates to a dynamic dragging and constructing module system with a 3D virtual element for an on-line exhibition, which comprises a network server, a client side computer and an Internet, wherein the network server is provided with a fire wall and is respectively connected with an organizer client side, an exhibiter client side and an audience client side by the Internet, and a virtual system of the on-line exhibition is constructed. The dynamic dragging and constructing module system is characterized in that the 3D virtual element which can be dynamically dragged and constructedfor the exhibition is stored in the network server and is a set of 3D virtual models which are manufactured based on the WEB3D of an X3D standard, the models are decomposed into different X3D subprogram bodies by aiming at the type of a virtual object to form a module icon library, icons are utilized to drag the 3D models so as to quickly construct a tableaux, and an individuation 3D virtual space is automatically generated. The invention solves the problems of singleness, independency, lower efficiency and the like of the prior method for constructing the on-line exhibition, reproduces the advantages of fullness, visualization and spatial impression of an entity exhibition vividly and forms man-machine interaction, man-network interaction and virtual-real interaction effectively.

Description

technical field

[0001] The invention relates to a dynamic drag-and-build module system with 3D virtual elements for online expos, in particular to a system that provides convenient, efficient and vivid dynamic drag-and-build 3D virtual elements for organizers and exhibitors of online expositions. Background technique

[0002] In today's information society, the expo industry is developing rapidly, which provides a stage for people all over the world to display and exchange information. However, traditional museums / exhibition halls / science and technology museums mainly adopt the physical display method, which has limitations in time, space, display objects, users and other aspects. With the development of computer technology and network technology, virtual expo technology is gradually solving this problem, digitizing display objects, and extending physical exhibits in terms of time, space, and content. At present, the vast majority of museums in the United States have joined...
