      I would like to do what you do from minute 8:21 to 9:13 on this video in VEX. I understand what you do but I can’t translate it into VEX ....I'm beginner. Many thx

      @@bastiensottero3727 Ahh - now I get what you mean. I put the origin points into a wrangle on the 2nd input. Detail Mode. I only use the points where the loop counter is i%4==0, get the point positions with those offset counters e.g. p1 = point(1,"P",i+chi("P1")); and create new points and primitives there. If you want you can join the patreon and download the tool asset I showed in the video. You can quit patreon directly afterwards but then you have the asset to check out the code I used here and in other videos.

      @@HristoVelev then your main point just needs to be the center of this formula. Thats the same I did for the voronoi. Just create the form you want and use a copy to point to place them where you need it.

    it is such a pity that same code does not work on different H versions... I use 18.5 from the moment there should be a circle or spiral H is not responding to the code anymore.
