Houdini VEX - Looping

A few variables are available for referencing in a Wrangle:

• @ptnum – current point number up to @numpt
• @elemnum – current index of this element up to @numelem

Their equivalents are @primnum, @numprim etc.

To loop over every point:

vector positions[] = {};
for (int i = 0; i < @numpt; i++) {
    vector p = point(geoself(), "P", i);
    push( positions, p);
}

Using foreach:

foreach(vector position; positions) { 
    // Do something;
}
