linux下基于S3C2440开发的步进电机驱动，一根信号线控制HB202M细分器即可实现步进电机速度和方向的控制-linux based S3C2440 development of stepper motor drive, a signal line control HB202M subdivision stepper motor controller can achieve the control of speed and direction

企业的量具品种繁多，且同种同规格量具就有多件，在日常管理中，如不进行一一细分管理，将为以后的计量检定带来很多麻烦。为了解决生产型企业量具计量检定管理工作电脑化，迅思科软件特开发出一套量具计量管理软件。-Measuring a wide variety of enterprises, and have the same kinds of pieces of the same size measuring tool in the daily management, if not one by one

FIXME: add a recursive box subdivision method to verify that tight bounds is correct.

细分曲面catmullClark细分算法代码，直接运行的结果为一个实例的细分结果-subdivision surface

该程序实现了Delaunay三角剖分的过程,能够对任意多边形实现三角化-The program implements the Delaunay triangulation of subdivision process, able to arbitrary polygon triangulation
