3D Rubik's Cube — online 3D modeling system based on WebGL

Aiming at the lack of 3D model design function of the existing 3D printing cloud service platform so that 3D modeling based on cloud was difficultly accomplished, an online 3D modeling system - 3D Rubik's Cube, was introduced in this paper. The online 3D modeling was achieved by Web front end technology such as the third-party graphics library of WebGL - Three.js, and the establishment of Web server by Node.js. 3D modeling function was further enriched and render effect was further enhanced by improved Phong reflection model, CSG tree and triangular patches intersection testing and division algorithm. The stability of 3D Rubik's Cube was verified by the deployment of this system onto 3D printing cloud service platform and the contrast test of FPS, load time with 3D Rubik's Cube and Clara.io.
