摘　　要：针对当前扩大化和复杂化的三维规划建模,传统的数据由于不能共享,在本地建模规划应用中已经不能满足多人协同规划开发流程的需求。提出了一种协同三维模型构建方案用以解决现在三维建模过程中遇到的协同困难。将WebSocket和WebGL(Web graphics library)等前端应用技术和计算机协同技术相结合,利用WebSocket建立不同用户之间的长效连接,实时分发和接受数据,WebGL建模及计算机协同模型实现了多人协同构建三维模型的Web应用,为利用最新的Web技术解决三维协同问题提供了思路。Currently, with the complexity and enlargement of the 3 D planning modeling scale,the traditional modeling planning application which’s data can not be shared has been unable to meet the needs of the current multi person collaborative planning development process.In this paper,a collaborative 3 D model construction programme is proposed to solve the difficulties in the process of 3 D modeling.CombiningWebSocket,WebGL and computer cooperative technology,using the ability of WebSocket to establish the long-term connection between different users and to distribute and receive data in real time,the ability of WebGL modeling and the theory of computer cooperative model can be used to build the web application of 3 D model.This paper provides ideas to solvethe problem of 3 D collaboration with the latest web technology.
