b is #b list of "pinned"/fixed vertices as indices into rows of V so it should not change during iteration. If you meant b in the formula, then yes it's changing because d is changing. d does not have the direction from rest_position to current_position but instead the direction of pi-pj (direction of spring ij) with the length of r. You may check the readme and tutorial file for more info. (I just followed the instructions there.)
in each iteration we need to find d, is that just a matrix that has the direction from rest_position to current_position? I feel like that's wrong because b is supposed to change multiple times per iteration. I'm honestly not even sure if my question makes sense, I'm very lost at what d is supposed to be.
Thanks in advance
