基于VC++调用COM组件探讨图形绘制软件的开发

Discussion on development of graphics drawing software based on VC++ calling COM components

针对目前图形绘制过程中因处理大量的矩阵运算和海量的数据导致的实时性不高、显示效果不佳的不足,研究了一种基于COM的混合编程算法.本文首先从理论上分析了传统编程的缺点,然后分析了混合编程中各种编程方法的的优点,以实时动态显示采集到的信号为例,通过实验表明,采用混合编程不仅可以减少程序复杂度和时间复杂度,比传统GD I方法在执行速率上提高了约25%～30.65%,而且能取得更好的图形显示效果.

Due to the disadvantage in real-time and its poor display resulted by processing a number of matrix operations and mass data in graphics rendering,it is researched that a kind of algorithm on hybrid programming based on COM.In this paper,it is theoretically analyzed that disadvantages in traditional programming and advantages in hybrid programming.It is demonstrated from experiments that,taking displaying the acquired signals real-time and dynamically for example,using mixed programming not only reduces the amount of program code and the time of running,and compared to the approach of traditional GDI the execution rate is improved from 25% to 30.65%,and it can achieve better displaying in graphics rendering.
