三角形法
三角形法
阿规则的等腰三角形成的这种方式。
It changes in whatever way it has to change so that when theta changes, a stays the same while b changes so that we keep a right triangle.它按着既定的方式改变,因此当θ改变时,a保持不变,同时b改变,从而我们保持为直角三角形。
Perhaps the most common and easiest way to do this is to use a 'triangle' shape between objects in an image with three objects in a frame positioned with one to each side and one more central.或许最常规、最简便的做法就是在图像物体间使用“三角”造型:3个物体,一边一个,另外一个置于中心。
