Hi,

How to change this python script, that every time I change base - point, the script updates itself?

Is it possible to do this without grasshopper timer, using Rhino EditPythonScript

Python script:

#############

import rhinoscriptsyntax as rs

def vectorField():
    cloud_id = rs.GetObject("Input pointcloud", 2, True, True)
    if cloud_id is None: return
    
    listpoints = rs.PointCloudPoints(cloud_id)
    base_point = rs.GetPoint("Vector field base point")
    if base_point is None: return
    
    for point in listpoints:
        vecbase = rs.VectorCreate(point, base_point)
        vecdir = rs.VectorCrossProduct(vecbase, (0,0,1) )
        
        if vecdir:
            vecdir = rs.VectorUnitize(vecdir)
            vecdir = rs.VectorScale(vecdir, 2.0)
            AddVector(vecdir, point)

def AddVector(vecdir, point):
    tip_point = rs.PointAdd(point, vecdir)
    line = rs.AddLine(point, tip_point)
    if line: return rs.CurveArrows(line,2)

vectorField()

#############
