Strange as it seems:
How many independent parameters do you think that have to be considered to completely define a straight line in a 3D space?
Clue: the number is smaller than six. Think of screws!

Five? Three distances defining a point in the 3D space and two angles defining the orientation (i.e. elevation and azimuth among others)

It sounds nice but it is not exact!
Take another chance!
Bye bye!

Do you mean less than five?

Four! … the answer is the Plücker Coordinates… I found it after an internet search with the words –screw — straight — line — .
Best regards
