How to reverse link direction

[Jerry]

I have an inertiacube linked to a model using the following code:

ori = add('intersense.dls')
orilink = link(ori,model)

How can I reverse the sign of the pitch so that when I tilt top of the
inertiacube away from me the top of the model rotates toward me?
I want the yaw and roll to remain unchanged.

There is no built-in link operator that can perform this inversion. However, the following code should work:

def InvertPitch(n):
	euler = n.getEuler()
	euler[1] = -euler[1]
	n.setEuler(euler)
vizact.onupdate(viz.PRIORITY_LINKS+1,InvertPitch,node)
