if your shape is convex it’s really easy to convert to triangles.
Calculate the center point.
Sort the points anticlockwise
Join the triangles (triangle fan)
It’s not as optimal as techniques like ear clipping/cdt but at least it’s fairly easy to implement.
With delaunay i would use indices, a getslice on indices with a bin size of 2 does the job, vertices count is 3, but i think i calculate using this pin spreadcount, so use select with 3 as input and select count will be indices count /3, and send that part in the vertices count.
Hope that helps, if you got more questions don’t hesitate to ask.
