Hi!
I'm processing some photogrammetry scans with millions of polygons and I'd like to choose 3 points and create a triangle out of those with a Detail Wrangle.
Is there a way my wrangle could search for the “Base Group” information found in the node called “pick_3_points” from the detail wrangle?

From wrangle, get point list from a group sop?

Is this what you were thinking - see attached?
Detail wrangle 1
Detail wrangle 2
Detail wrangle 1
i[]@pointnumbers; for(int i = 0; i < npoints(0); i++){ if(inpointgroup(0,"pick_3_points",i)){ append(i[]@pointnumbers,i); } } int firstindex = i[]@pointnumbers[0]; push(i[]@pointnumbers, firstindex);
Detail wrangle 2
addprim(0,"polyline",i[]@pointnumbers);
