Marine Oil-spilling Real-time Dynamic Visualization Research And Design Based On The Sea-land Integrated Platform

Global sea is very rich in oil and gas resources, accounts for about34%of totalglobal oil resources. With the development of global economy, the exploration onmarine petroleum resources has shown a fast growth trend. At the same time, Blowoutand shipping oil leakage accident more frequently, result in huge environmentaldamage and economic loss. In several recent major events such as Mexico gulf andBohai gulf oil spill, make the oil pollution become the focus of all fields’ attention. Atpresent, the related researches on marine oil-spilling visualization mostly tend to2D,but3D aspects there still exist many defects in physical model, simulation effect andsystem functions aspect. This subject aims to establish a highly immersed sense of3Doil spill interactive environment based on the sea-land integrated platform, and do thefollowing studies:1) Based on the current numerical simulation research on oil spill, to deduced anew discretization motion equation, which can reflect the motion law of oilspill in complex environment conditions, and more suitable for the realizationby computer graphics.2) In order to realize the best blend effects, critical technologies such as particlesystem,3D oil spill model, GPU rendering pipeline were studied.3) To make a comparative analysis of widely used3D rendering engines, andpoint out the defaults in the traditional OpenGL fixed rendering pipeline, atlast decided to select WildMagic rendering engine to render the oil.4) Realize the sea oil spill fence function, collision detection on ColDet libswere studied. Solved the low efficiency of collision detection between themassive oil particles.5) Realize some interactive functions, such as oil spill animation control,compass and eagle eye functions, and support the saving and loading of oilspill simulation and fence schemes.Through these research on the aspects above, this article established a completeset of3D visualization and real-time dynamic oil spill emergency treatmentmechanism, to make up for the short age in3D researches currently. It is proved thatthe system can to some extend simulate offshore oil leakage process and meet users’request on real-time and interactive operation. The research in this paper provided anew solution for marine oil spill accident treatment, and also taken a technicalfeasibility for the drift diffusion simulation, emergency decision-making of similar seafloater (such as Marine rubbish, Hu moss, etc), had long-term practical significance.
