We design a WEB3D-based application generator for VR exhibition, which provides management and edit functions for VR scenes and models. Because our work is based on WEB3D and B/S architecture, user can make VR application instantly and easily. We develop the web editor by UE4, so it can get an excellent rendering performance and preview and modify model in real time. In this development process, we solve many problems caused by packaging UE4 to HTML5, such as loading local files, web page jumping problems. In order to help users creating VR scenes quickly, we provide some common templates. Therefore, this work is considered as an efficient tool for nontechnical users to create applications of VR exhibition.
