Hi

I would need to know how the orientation (plane) of the pole vector of a RPIK solver is calculated. It's not the start joint, end joint or an average value of both.

I have to get the exact polve vector out of a chain with more than 3 joints.

greets

Its not calculated you supply it! Anyway the preferred angle defines the plane and direction the pole vector just defines rotation onto that plane.
