To expand on this, what you were seeing was the transform matrix representation of the point, which I prefer, as it is unambiguous.
Transform matrix:
NX OX AX LX NY OY AY LY NZ OZ AZ LZ 0 0 0 1 The N, O, and A columns represent vectors describing the axis of the new frame in the X, Y, and Z coordinates in previous frame (world), and the L column represents the distance to the origin in the previous frame.
Does the 4th column have something to do with conf then? Matrix representation has always been something I've struggled to wrap my head around but your description here is the first time its made some sense.
