3d Modeling System Online Based On WebGL

3D Modeling System O nline Based on Web GL, is an online web page version of 3D modeling platform, is a online tools, which is designed to help users to complete the 3D design works in a short period of time, and based on t he browser’s 3D modeling tool eliminates the customers with the use of 3D modeling technology threshold, so as to help the non-professional technical personnel to participate in the 3D design.The system uses WebGL technology graphics to accelerate the re ndering of 3D model, and do not need to install a large modeling software on the client, users only need to open the web page into the system, modeling tools can be simply and easily to use, which is really popular characteristic.At the same time, User can also export or import the completed model and scene, and also exchange and modify the model for each other, truly availability and practicality.The key technology of Web GL based 3D modeling is presented in the paper, such as 3D scene design, model rendering and operation, scene data processing method, et al. On the other hand, the paper has presented some method, such as model files preload and transmission of compressed files, to optimize the performance of the system. Under the condition of limited bandwidth, the proposed approach has the capability to render 3D scene data to the client in real time. Ensure that users in the process of modeling the correctness of the data of import and export, ful y improve the interactivity and usability of the system.
