You could achieve this by checking if a new point has a certain minimum distance to all the previously created points and save it, only if the minimum distance criteria is met.
import rhinoscriptsyntax as rs
sn = perlin.SimplexNoise()
pList = [ ]
for i in range(x):
for j in range(y):
for k in range(z):
perVal = sn.noise3(i * scaleX, j * scaleY, k * scaleZ)
if (perVal > lowerLim and perVal < upperLim):
if len(pList) == 0: # empty point list
pt = rs.AddPoint(i, j, k) # create first point
pList.append(pt) # save first point to list
else: # not empty point list
pt = rs.AddPoint(i, j, k) # create point
shortest_dist = sorted([rs.Distance(pt, prev_pt) for prev_pt in pList]) # find the distance to the closest neighbour
if shortest_dist >= minDist: # if the closest neighbour is far enough away...
pList.append(pt) # save point to list
a = pList
You need to add
minDist as a slider input!
Since, you are new to Python, you might not understand the following line:
shortest_dist = sorted([rs.Distance(pt, prev_pt) for prev_pt in pList])
It’s basically short hand for this:
distances = 
for prev_pt in pList:
dist = rs.Distance(pt, prev_pt)
sorted_distances = sorted(distances)
shortest_dist = sorted_distances
If you’re interested in this topic, simply google “python list comprehensions”.
I hope this helps.
