摘　　要：分布式远程绘制系统通过代价计算及代价预测来有选择地传输客户端渲染所需的资源以提高系统的自适应性,为此提出一种分布式远程绘制方法.该方法改进了传统的代价计算和代价预测算法,把视点移动对远程绘制造成的额外代价加入到代价计算中,并给出了代价预测算法.实验结果表明,改进后的算法可以提高远程绘制的质量,可以更加有效地利用网络带宽,并提高了当视点快速移动时远程绘制的流畅性.Distributed remote rendering system through cost calculation and cost prediction selectively transmit the necessary resources for client rendering to improve the adaptability of system. This paper proposes a kind of distributed remote rendering method. This method improves the algorithm of both cost calculation and cost prediction, add the additional cost which is caused by the movement of the viewpoint into cost calculation and design a cost prediction algorithm. The simulation results show that the improved method can not only improve the quality of the remote rendering, but also make full use of the bandwidth of the network and make the remote rendering more fluent while the viewpoint moves fast.
