流体在虚拟现实场景中扮演重要角色,基于物理模型的流体动画可以增强数值仿真的真实感。但通常的基于物理模型的流体动画渲染,如果没有采用并行计算,不能达到实时模拟的效果。使用异构计算平台Open CL对SPH(smoothed particle hydrodynamics)方法进行加速,充分利用了Open CL与图形渲染API的数据互通性,并采用了CPU和GPU的协同工作的技术,能够发挥硬件潜力;同时,采用库伦定律和SPH方法计算表面张力和粒子法线,初步的实验结果表明该方法有希望用于大规模流体仿真。 相似文献

To study the uncertain optimization problems on implementation schedule, time-cost trade-off and quality in enterprise resource planning (ERP) implementation, combined with program evaluation and review technique (PERT), some optimization models are proposed, which include the implementation schedule model, the timecost trade-off model, the quality model, and the implementation time-cost-quality synthetic optimization model. A PERT-embedded genetic algorithm (GA) based on stochastic simulation technique is introduced to the optimization models solution. Finally, an example is presented to show that the models and algorithm are reasonable and effective, which can offer a reliable quantitative decision method for ERP implementation. 相似文献
