摘要
探讨了加速显示的相关理论与技术,总结出移动环境下的限制性,并提出一套加速策略,结合最新的硬件GPU（graphics processing unit）加速技术,最终让矢量地图在移动环境下也能快速高效地显示,提高了地图操作效率。
Relative theories and technologies of accelerated display are discussed in this paper.It is concluded that limitations occur in a mobile environment.As a result,an acceleration strategy,integrating the latest acceleration technology of the hardware GPU is proposed.Consequently,vector maps can be displayed quickly and efficiently in a mobile environment,thus can effectively improve the map operation efficiency.
