Why won't this work? (GN Vector Rotate)

Trying to rotate each Point around the Position of the previous Point.

Trying to rotate each Point around the Position of the previous Point.

What’s your desired end result?

  1. Each point is rotated by a constant angle around the point prior, and this adds up along the chain? That produces a segment of a circle:
  2. Each point is rotated by an angle that increases with index around the point prior, and this adds up along the chain? That produces a spiral:
  3. Each point is rotated around the original position of the point prior, and this doesn’t add up along the chain? That produces a line:

    (Correct the first point’s position as you wish.)

All three methods shown are here:

And if it’s not any of these, how would you further describe what you’re looking for?

That’s awesome thanks. I still don’t really get when to use Accumulate Field.
