      David Kahl VFX nice :) I was looking at getting polar coordinates relative to a certain point, have you thought about that? There is a VOP b that gives you relative to the origin only...

      @@HristoVelev you mean a given point is the first origin point and it continues from that or do you just want to put a spiral on a point?

      David Kahl VFX I want to have sin curves radiating from a point, to fake high res cloth wrinkles to add on top of a vellum sim

      @@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.

      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

    • @DavidKahlVFX
      @DavidKahlVFX  6 ปีที่แล้ว

      @@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.

    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.
