分形算法调和的海浪模拟方法
Fractal reconciliation for ocean wave simulation
摘要
Abstract
A wave simulation approach based on fractal reconciliation was presented according to the problems of realistic wave modeling. The waves were classified into fundamental wave and high-frequency detail. The fundamental wave was implemented by combining sine wave superposition, the kernel of the method was modeling high-frequency detail using the fractal algorithm--mid-point random displacement ( MPRD) , and established a new parameter equation from feature data of ocean surface for fractal parameter optimization. At the same time, an improved view-dependent multiresolution model based on viewpoint distance, human visual properties, viewpoint-switches speed was able to reasonably adjust fractal reconciliation wave. On the other hand, the realistic effects with texture mapping and illumination model was achieved on GPU. Experiments show that the method is efficient for realistic wave modeling, and has better rendering speed.关键词
