  • $\begingroup$ Hey ! That's now working like a charm! (using the Dynamic@Point[points]). Thanks a lot for sharing this ! Once the simulation has been stoped, how do I extract the points {x, y, z} coordinates ? $\endgroup$ Commented Feb 7, 2014 at 0:36
  • $\begingroup$ @Cham As I said at the very end, the results are stored in points as {{x1,y1,z1}, {x2,y2,z2}, ...}. Should have put that line at the top together with the rest of the text. I can see how one could miss it. $\endgroup$ Commented Feb 7, 2014 at 0:37
  • $\begingroup$ Yes, the process is very slow. But the animation is VERY nice, and allows the user to stop the process once the "sculpture" has a nice appearance. I think this is a great piece of code, even if it's very slow. Thanks again ! $\endgroup$ Commented Feb 7, 2014 at 0:43
  • $\begingroup$ Oh, just a stupid question : I guess that the process is really random ? I mean that restarting the process will not give the same shape, again and again, isn't ? $\endgroup$ Commented Feb 7, 2014 at 0:45
  • $\begingroup$ @Cham Just be careful! Mathematica will crash if you leave it running (with the live animation) for a long time. This is one reason I didn't post this code originally, the other being that it's so slow I couldn't make the filaments grow inwards from a large sphere (as in the other post). Actually I took this code from a bug report I sent about a crash ... $\endgroup$ Commented Feb 7, 2014 at 0:46
