Data transmission device applied to Web3D (Three-dimensional) and method

Abstract

The invention relates to a data transmission device applied to Web3D (Three-dimensional), in particular to a device for transmitting data with the Internet. The data transmission device comprises a request judging device, a scene data reading device, a data conversion device and an interface mapping device, wherein the request judging device is used for judging the position of data requested by a client, and resolving position information such as a server where the data are positioned, a scope and the like; the scene data reading device is used for reading various types of three-dimensional objects in different scenes and converting object data into an XML (Extensive Makeup Language) encapsulating structure; the data converting device is used for converting the object data among the XML encapsulating structure, an SOAP (Simple Object Access Protocol) encapsulating structure and a JSON (JavaScript Serialized Object Notation) encapsulating structure; and the interface mapping device is used for establishing a corresponding mapping relation between data interfaces in a JavaScript module and an OpenGL module, and transmitting response data of a server end to a local OpenGL graphics library. According to the method and the device, integrated utilization of Web3D application and other application systems is realized, and data sharing, information management and maintenance and the like are achieved. The invention further provides a data control method applying the data transmission device.

Description

technical field [0001] The present invention relates to a device and a method for transmitting 3D data, in particular to a device and a method for transmitting 3D data using the Internet. Background technique [0002] As the public knows, with the development of the Internet, 3D graphics technology represented by VRML (Virtual Reality Markup Language) is merging with network technology to form a 3D graphics technology based on the Internet. The interactive 3D graphics technology (Web3D) on the Internet is breaking away from the 3D graphics of the local host and forming its own independent framework. , virtual communities and other fields are widely used. [0003] Although Web3D has a good development prospect, if the application is only for 3D graphics presentation without real-time interaction with users or data sharing and other functions, then this application is an information island and does not give full play to its application value, so Web3D Need a powerful seconda...

Problems solved by technology

[0005] At present, the SDKs in the 3D application field are basically aimed at desktop software products, and the secondary development SDK for Web3D has not yet taken shape. The main technical problem at present is how to encapsulate Web request data to support software systems across heterogeneous platforms; the second is how to implement HTTP. protocol cross domain request
