英文摘要： The study on key techniques of hybrid modeling and rendering is to combine the advantages of various current ocean simulation methods to real-time generate large-scale dynamic ocean scenes realistically and omnidirectionally display the dynamic meteorologic and geographical scenes above, on and beneath the sea surface. And could multi-scale visualize large-scale ocean current scene with huge data. The process of this project will have find profound significance and great potential application in the areas such as Military Affair & National Defense, Climatic Prediction, Navigation, Early Warning of Shipwreck & Rescue and Digital Entertainment, etc. This project intends to study the key techniques and novel methods of realistic modeling and real-time rendering for ocean scenes, including the hybrid modeling and rendering among the physical based simulation methods of ocean scenes; the hybrid modeling and rendering among the physical based and non-physical based simulation methods of ocean scenes; the realistic modeling and real-time rendering of scenes above and beneath sea surface; Modeling of ocean currents and their scalable dynamic scene display. At last we will construct the prototype system integrating these techniques
