What is the definition of an index?

the direction [x,y,z]

Okay, I see the pic now. You are starting from the origin. Just calculate where the point is in the table.

I'm not quite really sure if I get this right since it is in 3D and is very confusing.

Now, I have Direction 1 [0, 0.25, 0.3]

Direction 2 [0.4, 0.25, -0.3]

Would you please verify if what I have looks good?

Thank you in advance

Yeah, now it looks good. If you need to justify the distances, ue pythagoras theorem.

Alright, thank you very much for your clarifications.

The standard English term is "x, y, z components" not "indices". In "British English", the letters "x", "y", "z" in, say, u_x, u_y, or u_z would be "indices" (in "American English", "subscripts").
