So I have a person (A). Now I want to set the location of a second person (B) that should be standing in a certain position in relation to A. Like this:
(^ means a person that’s looking in that direction)
So the second person is standing behind the other person at a given angle (135 degrees) at a given distance (x). His rotation is the same. What I want to find is the location of person B. I can’t for the life of me figure out how to calculate this from A’s quaternion (or what keywords to google for ^.^), even though I realise it’s relatively simple o.O.
