In this tutorial we cover another Recursion example. This one is a bit more complicated than the last one. This one uses a reallycool trick in python to manipulate all values in a list by a number. Check the code below, but the syntax in this example is scaleVect = [ x - sc for x in scaleVect] Very cool.
import rhinoscriptsyntax as rs def RecursiveScale(objID,scalePt,scaleFact, scaleVect, num): if num == 0: return 0 else: sc = (1.0 / scaleFact) scaleVect = [x - sc for x in scaleVect] rs.ScaleObject(objID, scalePt, scaleVect, True) return RecursiveScale(objID, scalePt, scaleFact, scaleVect, num-1) objID = rs.GetObject() scalePt = rs.GetPoint("Pick Scale Center") scaleFact = rs.GetReal("Enter a scale Factor", 10, 0) scaleVect = [1.0, 1.0, 1.0] num = rs.GetInteger("Enter a the number of iterations", 10, 1) RecursiveScale(objID, scalePt, scaleFact, scaleVect, num)
