# Sierpinski Triangle

Paul Barton shared this question 9 years ago

Sorry I did not add this to the previous posting on the Sierpinski triangle but that posting appears to be locked.

I am not sure what counts as an iteration but I think this file is capable of creating 8 iterations. I'll let you be the judge of that. Be aware that on my computer, iteration 6 to 7 took about 20 seconds and iteration 7 to 8 took about 2 minutes. On attempting iteration 9 my computer crashed.

I have used a different approach, from that demonstrated in the earlier post, to create each iteration. I used some buttons with scripting that employs execute and sequence commands.

Cheers

Paul,

For me on a 1280x800 resolution screen, six iterations is the maximum viewable.

Here is a version that is created by random points :) http://www.geogebratube.org...

Hi slik,

Thanks for checking it out.

Ahah, I agree that 6 iterations is the maximum viewable to still be able to see the whole of original triangle. You'd need extremely good eye sight to see more than 6 iterations without zooming. However, with zooming in you can see that iterations 7 and 8 have been calculated correctly. So at least iterations 7 and 8 maybe calculated.

Cheers

It's strange, but the topic is really locked

I couldn't properly use your file. There's a problem about the list's name when I try to use the iteration. I'm using GeoGebra 4.0.40.0

Switch language to UK or Australian English (the scripts use eg Enlarge rather than Dilate)

Thank you murkle and congratulation Paul Barton! Your way is the best way I've seen for Sierpisnki! Is lighter than my file!

Here is an improved version that doesn't fade at the higher iterations.

Same caveats as before. Be patient to get to iteration 8 and zoom in to see the small triangles of the 8th iteration.

Cheers
