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...
A new method for nearshore wave simulating is introduced. Firstly, parabolic 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 root mean square wave height, the peak wave period and the mean wave direction can be calculated. Instantaneous surface elevations can also be obtained from the model. Then,...
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...
