OpenGL多线程电子地图显示研究

Electronic map display based on OpenGL multi-thread

电子地图显示速度直接影响地图用户的交互感受,一直是地图制图者关注的一个重点。本文从地图显示速度与适人化交互操作的关系出发,分析了GDI与OpenGL的特点和差异,提出了基于OpenGL的电子地图显示的方法,重点对基于OpenGL多线程的电子地图快速漫游显示技术进行了分析讨论,并进行了实验论证。

The display speed of Electronic Map directly affects the interactive experience of map users,and it is always the hot issue to cartographers.This paper formed the relationship between the display speed of electronic map and the humanoid interaction,analyzed the characteristics and the difference between GDI and OpenGL,and proposed a method based on OpenGL to display electronic map.It discussed the speedy display based on OpenGL multi-thread and did some experiment.
