A simple Rhino Python script that generates fractal curves. Example is the test with Gosper-Peano curve. However the script is not supporting segment directions, that is why the result is not the intended curve. Curve directions could be implemented in the future. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 # Drawing Simple Fractal Curves # 31.07.2017 www.designcoding.net – Tugrul Yazar import rhinoscriptsyntax as rs import copy initials = rs.GetObject("Select Initial […]
