Wave Spectrum Simulation Algorithms And Programming

In recent years, due to the 3D simulation applications in the 3D visualization, gaming industry Etc. Make the computer graphics and virtual reality simulation technology get very big development. In many cases, simulate the nature scenery. Water as natural scenery, with its liquidity, transparency, and by transparency raises complex optical properties, to make it a simulated the difficulty in the simulation. The wave's simulation is a branch of water simulation.Through in-depth analysis of the current mainstream waves modeling algorithm, analysis and summarized the algorithm, based on the wave spectrum waves modeling technology, is in oceanography years of observation data and research is conducted on the basis of modeling, it embodiment of the real waves characteristics. This paper based on the wave spectrum waves modeling technology and rendering technology for some improvement. Through FFT and Phillips spectrum calculate the current wave height field, and establish the waves through highly field grid, generating each frame of the waves.Use view-dependent technique simulates a boundless sea, when the spindrift in simulation, through analysis of the sea waves generated by the sea waves, because of the related conditions by using particle realize, spindrift the effect will be affect system real-time, so this paper adopts mipmap realized simulated the spindrift. The last effect has certain realism, and meets the requirement of real-time.Finally this topic research aim is to establish a suitable for large-scale in wave's simulation model, through the waves of light and texture, in order to achieve realism and render real-time good waves simulation. This paper use view-dependent technology and wave spectrum method can realize unlimited waves simulation, through the wave's demonstration system, classified system module, the simulation results also meat real-time and realistic requirement.
