As always to the rescue…
Thanks, Henry!

@Toadstorm: Are you sure matrices can be qmultiplied? Houdini gives me an error “Errors or warnings encountered during VEX compile:
No matching function for vector4 qmultiply(vector4; matrix3). Candidates are: vector4 qmultiply(vector4; vector4)”
. This would in a certain way make sense to me (with my limited grasp of math), since I thought matrices were in the domain of linear algebra and quaternions in the non-linear domain..

@Aizatulin: Thanks for the example. It's a bit overwhelming, I can't yet discover if it would apply to my case. I am looking for a per point-comparison: ((diff orientation between P1 and P2) added to the existing rotation of P3). I do however understand that the dihedral function might apply here..

That I indeed understand… but more on on a fundamental level I was unaware they are to be combined
