Using some vector maths and Python, Marco Giordano shows some methods for finding the position of a Pole Vector in Maya, which is essential for a rig to prevent popping of any IK limbs during animation.

how to use some vectors math with python in order to find the correct place for a poleVector

As with anything, there are more methods for doing something like this, showing there is not one right answer, here Marco shows how you are able to find the position of a poleVector in Maya at any given time, and using that information to create a joint chain that will not “pop” during animation. Marco has other great tutorials like this one, and creates more rigging tutorials, tips, and tools on his site.
