how to get "score"

[Iraanol]

Hi SunskyF,

Thank you for your work. I want to ask, how to get score of vanishing point.txt. I mean like =

vx	vy	vz	score	numLines
-0.8362	-0.54843	-0.00144	4546.04	285
-0.0979	0.995197	-0.00033	4010.68	315
0.978255	-0.20741	-0.00048	2365.94	180

I just knew, that is score of vanishing points, but how to calculate it?

Thank you very much
