請教各位
在reference center中,有一個LOCUS的例子(如下),要用什麼方法做出這個隨A點變化斜率的線段呢?謝謝!
Locus of a segment, driven by a point: In the illustration below left, segment k is constructed to have a slope determined by a calculation involving its x and y values. As driver point A moves along segment CD, the calculation's value changes, and so does the slope of segment k. The locus below right shows the locus of the slope segment for various positions of point A on its domain.
