一般书上把这几个变换用照相机类比，其实每个变换都是产生着一个4x4矩阵，然后与当前矩阵(Current Matrix)相乘，得到一个坐标变换矩阵，最后把世界坐标系（欧式空间）中的物体变换到屏幕坐标系中。

In general, low current matrix switching can become complex and is best explained by illustration.
总体而言，小电流矩阵切换可能会变得非常复杂，将通过图示进行说明。
All the special techniques used to minimize interferences for low current multiplexing also apply to low current matrix switching.
小电流复用切换中所有用来减小干扰的技术也都适用于小电流矩阵切换。
Next, rotate and store this matrix; then, offset from the current coordinate system with translate (which is applied from the previously rotated and translated matrices), and draw a red ellipse.
接下来，旋转和恢复这个矩阵；然后，使用translate设置与当前坐标系统的偏移量(这是从之前旋转和转换的矩阵应用的)，并绘制一个红色椭圆。
