geometry matrix rotations to pops

[dyei nightmare]

Whassap, i need to translate this vex code from geometry context to pops context, what i know is that the data stream coming from pops all starts invoking orient, but how do you apply this code in pops?

 

matrix3 current_xform = primintrinsic(0, "transform", @ptnum);

matrix3 goal_xform = maketransform(normalize(v@v), chv("up"));

matrix3 delta_xform = invert(current_xform) * goal_xform;

vector4 qdelta = quaternion(delta_xform);

vector torque = qconvert(qdelta);

v@targetw = torque;

f@spinresist = 2.2;
