In this tutorial, we modify a couple of lines from the last tutorial to change our circles to spheres and we add the 3rd dimension to our growth. In the code snippet below, I've simply commented out the code for 2D cirlces and replaced those lines with 3D spheres. Instead of rs.AddCircle() we are using rs.AddSphere(). 

import rhinoscriptsyntax as rs
import random
 
def placePt(x_range,y_range,z_range):
    x = random.uniform(0,x_range)
    y = random.uniform(0,y_range)
    z = random.uniform(0,z_range)
    pt = [x,y,z]
    return pt
 
rs.EnableRedraw(False)
 
ptZero = [50,50,50]
pts = []
pts.append(ptZero)
#circleZero = rs.AddCircle(ptZero,0.5)
sphereZero = rs.AddSphere(ptZero, 0.5)
 
 
 
for i in range(0,1000):
    pt = rs.AddPoint(placePt(100,100,100))
    index = rs.PointArrayClosestPoint(pts,pt)
    cp = pts[index]
    vect = rs.VectorCreate(cp,pt)
    unitVect = rs.VectorUnitize(vect)
    subVect = vect - unitVect
    newPt = rs.MoveObject(pt,subVect)
    #rs.AddCircle(newPt,0.5)
    rs.AddSphere(newPt,0.5)
    pts.append(newPt)
 
rs.Redraw()

Hi Zach, Thank you very much for this set of tutorials, they're truly awesome! I would love to see a case study video of python used within a architectural context. All the best, Charles
