We will be using the Damped Harmonic Oscillator formula to create some pseudo spring constraints.

    This is a very good and helpful video ,. But I find that in the beginning of the third video , I think you may calculate the wrong anglular accerlation speed. When crack the transform I think the result is already the target angular speed substract the current one . Here's my code below .

    matrix3 tr = primintrinsic(0,"transform",@ptnum);
    matrix3 animtr = primintrinsic(1,"transform",t);
    matrix3 off = invert(tr) * animtr;
    vector ang = -cracktransform(0,0,1,0,off);
    vector f= -chf("k") * ang - chf("c") * v@w;
    v@w += f;
