直线、圆、椭圆二维图形的生成。直线的生成算法有DDA、Bbresenham、point,圆的生成算法有bresenham等

此系统还包含裁剪操作。

曲线的生成算法：bezier曲线

三维操作:三维物体旋转变化、穿越三维空间、虚线三维空间-Straight, round, oval to generate two-dimensional graphics. Straight-line algorithm to generate the DDA, Bbresenham, point, circle generation algorithm has bresenham such as the system also includes a cutting operation. Curve Generation Algorithm: bezier curves of three steps: changes in three-dimensional objects rotating through three-dimensional space, dotted line three-dimensional space
