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

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. However, this embodiment cannot be used to limit the present invention. Any similar structure or similar changes adopted in the present invention shall fall within the protection scope of the present invention.

[0029] A dynamic drag-and-build module system with 3D virtual elements for online expositions such as figure 1 Shown. It is composed of a network server 1, a client computer and the Internet 3. The network server 1 is provided with a firewall 2, and is connected to the organizer client 4, exhibitor client 5 and audience client 6 via the Internet to form an online expo The virtual system is characterized in that: the web server stores the 3D virtual elements that can be dynamically dragged and built in the Expo. The 3D virtual elements that can be dynamically dragged and built are a set of 3D virtual models made by WEB3D based on the X3D standard, which are aimed at virtual objects. The type decomposes the model into different X3D subroutine bodies to form a modular icon library. Use the icon to drag the 3D model to quickly build the scene, and automatically generate a personalized 3D virtual space.

[0030] The user interface of the organizer client is as figure 2 As shown, it includes a management module 210, a module icon library 220, an audio-visual module 230, and a drag building area 240;

[0031] a) The management module includes three parts: information management 211, authority setting 212, and qualification review 213;

[0032] b) Module icon library 1 is composed of different modules, including scene selection 221, road construction 222, venue construction 223, hall layout 224, green planting 225, and advertisement posting 226;

[0033] c) The audio-visual module includes voice input 231, voice explanation playback 232, and external shooting scene input 233;

[0034] d) Towing area 240 is the towing area of ​​the entire expo venue.

[0035] The user interface of the exhibitor client is as image 3 As shown, it includes the second module icon library 310, the audio-visual module 320, and the second drag building area 330;

[0036] The second module icon library consists of different images, including exhibition hall selection 311, booth construction 312, exhibit display 313, advertising 314, virtual staff 315, and business card request and release 316;

[0037] The audio-visual module is consistent with the user interface of the organizer's client;

[0038] Towing area 2 is the space area that can be used for expo towing.

[0039] The 3D virtual elements of the online expo and the dynamic drag building program are stored in the web server 1. The organizer client 4, the exhibitor client 5 and the audience client 6 can access the data in the web server 1 through the Internet 3 and use the online expo 3D Virtual elements and dynamic drag-and-build procedures. The data in server 1 is protected by firewall 2.

[0040] The organizer client 4 sends an information transmission request to the web server 1 via the Internet 3. After the web server 1 transmits the virtual elements of the online expo to the organizer's client computer, the 3D virtual elements installed on the client computer can be used for dynamic dragging of the online expo The program started, the organizer starts to register the organizer’s information on the web server 1 and then enters figure 2 The interface shown. Set login and modify permissions. After the setting is completed, the virtual exhibition site can be towed and constructed, and billboards can be placed. In the management dial 210, the organizer can view the registration information of exhibitors and visitors in the information management 211, classify and manage different types of exhibitors, and macro-allocate the location of the virtual exhibition hall. In the permission setting 212, the organizer can set permissions according to different identities. For example, the organizer can log in as an administrator to view and manage any information, and can drag and build virtual elements of the entire scene of the virtual expo. modify. Exhibitors cannot change the scene and facilities, but can only manage their own booth construction, and can view part of the information of registered visitors. Visitors can only browse in the virtual exhibition hall, and can view and exchange related exhibits, but they have no right to change the facilities. Visitors need to register unit information and exhibit information when logging in to the server for the first time, and submit an application to the organizer. The organizer will review all aspects of the exhibitor's information in the qualification review 213 and decide whether the unit can participate in the exhibition or what rectifications need to be made.

[0041] In drag construction area one 240, the organizer can select corresponding virtual images from the six tags 221 to 226 in module icon library one 220 and drag it to drag construction area one 240 to build a complete virtual scene. Including the scene environment, road planning, venue distribution and construction, green planting, etc., exhibition information, exhibition layout plans and advertisements can also be posted at appropriate locations.

[0042] Exhibitor client 5 can enter such as image 3 As shown in the interface, in this interface, the user can drag the virtual elements corresponding to the six tags 311 to 316 in the second module icon library 310 to the second 330 drag building area to build a personalized booth, display exhibits, and place virtual workers Exhibit explanation and company introduction, and can ask the audience for business cards.
