设计实现直线的DDA算法或BRESENHAM算法，并在此基础上进行下面的实验： 绘制金刚石图案 -Design linear algorithms or DDA BRESENHAM algorithm, and on this basis for the following experiments : Drawing diamond logo

这也是一些基础光学实验的一些例子，主要学习菲涅尔衍射。相信对学习光学是很有作用的-This is some basic optical experiments a few examples of key learning Fresnel diffraction. I believe it is useful to study the role of optical
