以华铸CAE软件图形系统为例 ,介绍了在均匀网格有限差分系统中 ,如何应用DIB位图和面信息缓冲等技术进行图形加速 ,并在此基础上实现了图形的实时转动和动态剖切 ,从而建立了一套完全基于差分单元的图形系统。
Taking Huaxia CAE software graphics system as an example, this paper introduces how to apply the technology of DIB bitmap and surface information buffering to accelerate the graphics in the uniform finite difference grid system, and realizes the real-time rotation and dynamic profile of the graphics Cut, thus creating a completely based on the differential cell graphics system.
