As in the title, any ideas ?
I was trying that but It didn't work (A and B are vectors):
but maybe I don't understand how the interpolation works or maybe I used the wrong interpolation, I don't know.

please use this:

void AdjustValTime (Flt &v,Flt target, Flt step ); // adjust value by smooth time interpolation, "v=LerpTime(v,target,step);"

Flt step=0..1
AdjustValTime(cam.at.x,dest.x,step);
AdjustValTime(cam.at.y,dest.y,step);
AdjustValTime(cam.at.z,dest.z,step);

for the next release ill make a
AdjustValTime(Vec &, Vec&, Flt step);
function

Ok thanks
