hye I'm going to write smd format but I have a problem... I don't know how can I calculate angle from the change positions ... I know by you that it's refered to euler angles but I don't know which it is! ...Tait–Bryan angles or euler angle... and what are their priorities? Euler angles (z-x-z, x-y-x, y-z-y, z-y-z, x-z-x, y-x-y) Tait–Bryan angles (x-y-z, y-z-x, z-x-y, x-z-y, z-y-x, y-x-z).

can you help me?
