Yes. All of the joints start out at 0d in the specified order direction (xyz, zyx, yzx, etc.). You can then apply 'orientation' to the joint for body part alignment. Notice how orientation does not affect rotation! The joints still start at 0d. This is the zero-based part of Poser's JPs. Then, most likely for IK, the pose is relaxed by the figure creator, adding slight bends to legs and arms. This pose is memorized and saved. Thus the initValue represents that 'state' of pose. No need to specify that the 'zero pose' of a figure is, well, zero. Right? ;)

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
