Abstract: This paper presents one web-based interactive illustration system for energy stations using Unity3D as render engine. Interaction, scene rendering and data-driven visual analysis are the key technologies for this study. One low-coupling logical framework of virtual illustration is designed for five view layers using state pattern. From the viewpoint of event response and trigger on-demand, one concise human-computer-interaction interface is carried out. High-quality visualization of energy station is realized using Unity3D, which includes dynamic texture, water animation in water pipe, modeling and bake. Json database is used as transfer hub for external data access. Thus the dynamic graphs of real-time data are shown on the web. Implementation of the above design validates the advantages of enhancing the scene realistic and user experience.

Key words: virtual reality, online interaction, data visualization, unity3d, energy station illustartion
