|

// A check mark is defined by three points in some coordinate space. Here, we
|
||||
// define these points in a unit coordinate system, where the range of the x
|
||||
// and y axis are both [-1, 1].
|
||||
//
|
||||
// Note that we do not hard code `p1y` in case we wish to change the
|
||||
// size/shape of the check mark in the future. We want the check mark to
|
||||
// always form a right angle. This means that the dot product between (p1-p2)
|
||||
// and (p3-p2) should be zero:
|
||||
//
|
||||
// (p1x-p2x) * (p3x-p2x) + (p1y-p2y) * (p3y-p2y) = 0
|
||||
//
|
||||
// We can now rejigger this equation to solve for `p1y`:
|
||||
//
|
||||
// (p1y-p2y) * (p3y-p2y) = -((p1x-p2x) * (p3x-p2x))
|
||||
// (p1y-p2y) = -((p1x-p2x) * (p3x-p2x)) / (p3y-p2y)
|
||||
// p1y = -((p1x-p2x) * (p3x-p2x)) / (p3y-p2y) + p2y

// devising the above equation and unit coordinate system approach!
