Web three dimensional (3D) synchronous conference system based on rendering cloud and method of achieving synchronization

Abstract

The invention relates to a Web three dimensional (3D) synchronous conference system based on rendering cloud and a method of achieving synchronization. The Web three dimensional (3D) synchronous conference system based on the rendering cloud and the method of achieving synchronization comprise a file transmission module, a server rendering module, a display module, an interaction module, a synchronization module, a conference management module and a multi-media communication module. Rendering technology is adopted by the system. Various kinds of large-scale or ultra-large type three-dimensional models can be browsed synchronously controlled, directly and fluently through a browser, thus any plug-in module is not needed to be installed. Due to the fact that a manipulation model can be synchronously browsed by multiple users of different places movable cross platform (such as a mobile phone terminal and a personal computer terminal) is supported, thus synergic operation is achieved. Due to the fact that only rendered pictures can be obtained by the client terminal, model data can not be obtained, thus data safety of a user is guaranteed. The problem that communication difficulties of a traditional multi-user network conference caused by the fact that data size of transmitting graphic images is large is solved.

Description

technical field [0001] The invention relates to a communication conference system, in particular to a Web3D synchronous conference system based on cloud rendering and a method for realizing synchronization. Background technique [0002] There are many ways to realize the existing web3D system. For example, the Chinese patent application with the application number CN2010188278.8 discloses an editable webpage three-dimensional geometric modeling rendering method, which belongs to the technical field of computer graphics processing. The present invention uses a rendering engine based on a scene tree and analyzes the data exchange protocol to realize web3D. By analyzing the geometric modeling in the graphic nodes, the geometric modeling workshop of the rendering engine is used to generate geometric modeling objects. Edited 3D geometry rendering. The application uses a local rendering method, which requires the use of plug-ins. At the same time, it does not explain the cloud re...

Problems solved by technology

[0009] The Chinese patent application with the application number CN200510086338.4 realizes the method of synchronizing the model and operation in the collaborative design communication. The operation is based on the same model, and the operations of all clients are finally reflected on the same model. This kind of data integration and transmission times are many, and the data The amount is huge, and it is impossible to realize the browser-based viewing operation model, and it is also impossible to realize synchronization on various mobile smart terminals (smart phones, Pads, etc.)

[0010] The Chinese patent application with the application number CN200410037325.3 is based on the coordination of the command / parameter mechanism, which realizes the method of centralized assembly and communication of parts designed by different designers, but the silkworm chrysalis adopts the newly standardized virtual reality modeling language as the model. Although the expression language partially reduces the transmission volume of the network and realizes the communication between the communication subjects, it also shares all the information in a shared assembly space, and the content of the information needs to be transmitted unchanged, and the model also needs to be downloaded to the local , must use the local rendering, and then interact with the server, it is difficult to realize Web3D, and it is also difficult to realize synchronous browsing and manipulation of large and super large 3D models on mobile smart terminals

[0011] None of the existing teleconferencing systems mentioned above involve cross-platform teleconferencing, especially when mobile phone participants communicate through the existing teleconferencing system, it is basically impossible to complete the synchronous communication of large and super-large models. The transfer volume is too large to be used normally

At present, with the rapid popularization of various mobile terminals, there is an imminent need for cross-platform professional technical communication, especially communication based on graphics and images. At the same time, participants are required to communicate anytime, anywhere, and perform various operations such as annotation and editing. The traditional conference mode has a large amount of graphic and image data, and it is necessary to download the model to the local, and rely on local rendering for display, which makes communication difficult and impossible
