Create point on the middle of a primitive

[nghiatranduc94]

Hi, So I'm trying to create a point on the center of a primitive like the picture I've attached. Can anyone help me out?

- Scatter will create the point but it is randomly, not on the middle of the grid

- I've tried other centroid point methods but the point is outside of the mesh. So I'm stuck here

Prim wrangle 1 : 
 

int pts[] = primpoints(0,@primnum);
vector center = 0;
foreach(int pt;pts){
    center += point(0,"P",pt);
}
center /= len(pts);
v@center = center;

Wrangle 2 ( run in detail ) :
 

int nprim = nprimitives(0);
for(int i = 0; i < nprim; i++){
    vector center = prim(0,"center",i);
    int pt = addpoint(0,center);
}

or you can use two Sop : Enumerate  Sop and Extract Centroid  sop to do that .

Hi Nghia,

you could fill the 2D mesh with lots of scattered points and measure / sort their distance to the outline of the mesh.

To get the furthest mesh point to the outline, try the distance along geometry-node.
