@omar,
I feel like I've developed all these micro-tactics for making and finding software that meets this standard https://hachyderm.io/@dubroy/111658490778296619 like
- stuff that's written in C and uses a Makefile tends to work like this
- "single-file libraries"
- stuff that is 20+ years old and hasn't been updated but has elaborate API documentation/header comments

![The Truth
Source code in opencv
The truth is, as usual, in the source code of opencv. Typically, we see the relevant code blocks,
x0 = x = (x - cx)*ifx;
y0 = y = (y - cy)*ify;
// compensate distortion iteratively
for( j = 0; j < iters; j++ )
{
double r2 = x*x + y*y;
double icdist = (1 + ((k[7]*r2 + k[6])*r2 + k[5])*r2)/(1 + ((k[4]*r2 + k[1])*r2 + k[0])*r2);
double deltaX = 2*k[2]*x*y + k[3]*(r2 + 2*x*x);
double deltaY = k[2]*(r2 + 2*y*y) + 2*k[3]*x*y;
x = (x0 - deltaX)*icdist;
y = (y0 - deltaY)*icdist;
}
This confirmed my guess and the math equations in the opencv tutorial is not correct.](https://social.omar.website/fileserver/01PG4R73NMJC888MJM2KBM4CFF/attachment/original/01M8VPTJTBYHK78C48QP46Y57Y.png)
