rotate point one by one to keep line's length

[天城守卫]

I want to rotate point one by one,so i can keep
the line's length.
I use For loop SOP,because it has feedback ,update P every time.

but For loop is too slow,when i have a lot of points.

I want to know how to achieve this with VEX "for loop" function.

Here, its basically the same idea as the curve unroll thing I posted here a few days ago. The idea is to move each segment to the origin, rotate by the accumulated rotations up to the current point, put back to the accumulated rotated positions (full credit goes to another odforce post on this sort of rotation trick I stumbled upon)
