Research On WebGL-based Physical Interactive Technology And Its Implementation

Traditional interactive style greatly limits the development of interaction design, andhas great limitations to the rendering effect and the user experience, so the study of thetechnology of physical interaction it is particularly important.With the development ofWeb3D technology,Web applications become more common, the study of interactivetechnology on the Web pages are increasingly important.The emergence of WebGLbrings new challenges to the ever-changing interactive technology, and brings a lot ofopportunities to the development of physical interaction on Web pages.Nowadays,WebGL-based physical interaction has been widely applied in many fields. To keep upwith the development of The Times, the research of WebGL-based physical interactivetechnology and its implementation has been produced.Completed the research and discussion on WebGL-based physical interactivetechnology and its implementation by learning a series of related knowledge with WebGLand programming the actual modeling.First of all, the research on WebGL-based physical interactive technology and itsimplementation, analyzed and compared the implementation plans of Web3D technology,found that WebGL with absolute advantages, and have a study on WebGL and the relatedtheory with it. Because the native WebGLAPI is very low level and developing code withit will be very complicated,and so requires us to select a engine technoloy of WebGL toreduce the programming effort. Therefore, compared the several current mainstreamengine technologies of3D, and selected the Three.js as the framework of WebGL.Subsequently, WebGL-based and Three.js-based techniques of physical interaction weredescribed in detail, and have a implementation according to the working principle. In theend, the LOD optimization algorithm is applied into WebGL technology to enable thespeed of WebGL rendering can be improved.
