For perfecting the oil spill simulation view system of marine search and rescue simulator, based on the tidal current numerical calculation, considering oil movement mathematical models, designing a collision detection algorithm between oil and island, using texture rendering and plane refraction technologies of Open Scene Graph, finally the simulation and 3D visualization of oil spill on the sea...
STCW78/95 convention proposes new requirements for operation training of special purpose ship, so it becomes vital and necessary to realize semi-submersible heavy lift vessel handling simulator. The visualization of semi-submersible heavy lift ship handling simulator can be realized under the Visual C++ and OSG visualization development environment. The core technologies are described in details such...
Search and Rescue (SAR) at sea is one of the most important humanitarian activities and also an extremely complex operation based on the coordination of each unit within search and rescue event. Taking real equipments to do SAR rehearsal has many disadvantages such as high cost and great danger. In order to overcome these shortcomings and enhance the flexibility and the collaborative ability of each...
Light interaction considering scattering and absorbing is implemented with some simplicity physically. Dead reckoning based calculation is used during the implementation. After the 3D cloud being integrated using cellular automata clouding modeling method, experimental results show that it has realistic effect with fast rendering speed on a common PC. The method in this paper is very suitable for...
Based on the previous work of modeling dynamic 3D cloud using Cellular Automata, this paper renders realistic 3D cloud for Marine Search and Rescue Simulator visual system in real-time. Physically based light interaction is implemented by Open Scene Graph with a common PC. Light scattering and absorbing is considered. After the 3D cloud integrated into the visual scene, experimental results show that...
This paper introduces a new method for simulating nearshore wave. Firstly, elliptic mild-slope equations are set up according to the simulation area and input waves. After solving the equations, the integral wave parameters such as the wave height, the surface elevation etc. can be got. Secondly, the integral wave parameters are composed into a float texture. Finally, a viewpoint-dependent sea surface...
