Question

If you have 2 coordinates: (1,1,1) and (0,1,2) - how do you get the direction vector?

Answer 1

so write both of the coordinates in vector form.

subtract the two vectors accordingly to get the directions as you want. B from A if you want B to A, and vice-versa.

Answer 2

I don't follow :(

Answer 3

So the direction vector is <(-1,0,-1)>?

Answer 4

2-1 = 1 on the end there

Answer 5

if no direction is specified, i think the convention is to make the x component positive

Answer 6

rather 1i + 0j -1k

Answer 7

Oops, <(-1,0,1)>. Is this correct however?
I see! That's really helpful, thank you both! :)
