Some more helpful vex that I'm trying to type less often
1: Move to set on Grid and Set Pivot to Origin
in a point wrangle...
vector centroid = getbbox_center(0);
vector dist = centroid - 0;
vector min =getbbox_min(0);
vector max =getbbox_max(0);
v@P -=dist; v@P.y+=(max[1]-min[1])/2;
2: Random pscale
in a point wrangle...
float min = chf("min");
float max = chf("max");
f@pscale=fit01(rand(@id),min,max);
3: Remove Points by Percentage
in a point wrangle...
if(rand(@id)<chf("percentage")*0.01){
removepoint(0,@ptnum);
}
4: Normals Facing Away From Point With Radius
in a point wrangle... second input is point to face away from
vector P2=point(1,"P",0);
float dist = distance(v@P,P2);
float radius = fit(dist,chf("radius"),0,0,1);
v@N = (v@P-P2)*radius;
5: Give Each Object a Unique Name by Attribute
in a point or primwrangle... credit to Nate Lapinski
s@name = sprintf("obj_%d",@id);
