摘　　要：针对分形方法生成大规模地形数据时计算量大和运算速度慢的问题,提出基于GPU加速的分形地形生成方法,将Diamond-Square分形地形生成算法转化为CUDA线程块并行执行过程,使地形生成过程完全在GPU中加速执行,在取得较好模拟效果的同时,显著提高了算法的运算速度。Due to the problems existing in generation for large scale fractal terrain,such as heavy calculations and low speed,a new generating method was proposed based on GPU acceleration for fractal terrain. This method converts the Diamond-Square algorithm into the process of parallel CUDA thread blocks,and then the generation for terrain is executed completely through GPU. So the algorithm increases speed evidently and meanwhile it achieves a good effect.
