坐标系统的设置与转换 Change & Create CS
这篇文章主要研究局部坐标系统转换。这个问题涉及的数学知识非常简单,但是很复杂。
This part delves into the local coordinate system transformation. The mathematics of this problem are simple, but elaborate.
转换是直接修改坐标系统,这样左上角会发生偏移。
Translation simply changes the coordinate system so that the upper-left corner exists at a new offset.
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。
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.
