2011年8月6日 · I have been looking at how to reflect a point in a line, and found this question which seems to do the trick, giving this formula to calculate the reflected point: Given (x,y) and …

2013年7月1日 · For a collision algorithm I am developing, I need to find out how to reflect a line over another. Line 1: y=ax+b Line 2: y=cx+d Line 3: (a result of reflecting line 1 over line 2) …

2014年3月14日 · That is really a specific example of reflection over a line, where the line happens to be the x axis. (ie y = 0x + 0) If you want to reflect over another line, you can use a matrix. …

2010年7月22日 · Given a point (x1, y1) and an equation for a line (y=mx+c), I need some pseudocode for determining the point (x2, y2) that is a reflection of the first point across the …
