Tower of Hanoi[edit]

#1 - Tower of Hanoi animation
#2 - another version with four discs

Whilst following up on a previous Feature Picture, I noticed that User:Aka has some other impressive pictures, including this animation of the Tower of Hanoi puzzle. - Solipsist 10:40, 20 Mar 2005 (UTC)

  • Nominate and support - Solipsist 10:40, 20 Mar 2005 (UTC)
  • Support. Although I think 4 discs would probably be better for illustrating the recursive nature of the solution, I think this is an excellent illustration. →Raul654 10:50, Mar 20, 2005 (UTC)
  • Support. I agree that more discs would be an improvement, but this still got an "Oh. Oh, wow." out of me. —Korath (Talk) 16:40, Mar 20, 2005 (UTC)
    • And even more support for the four-disc version. —Korath (Talk) 20:09, Mar 22, 2005 (UTC)
  • Support the 4-disk version. -- BRIAN0918  18:25, 20 Mar 2005 (UTC)
  • Support Pretty cool but would be heaps better with more counters--Fir0002 09:59, 21 Mar 2005 (UTC)
  • Support contributes to the article, nice colorful animation. Mgm|(talk) 11:59, Mar 21, 2005 (UTC)
  • Oppose. Very cool, but an extra disc is needed. — Matt Crypto 16:26, 21 Mar 2005 (UTC)
    • Support only if done with 64 discs...
  • support although i would like to see the ground marked showing that there are only 3 positions on which they can sit 19:00, 21 Mar 2005 (UTC)
  • support titillating pic. Agree it would look even better with a 4th disc, though. Circeus 22:08, Mar 21, 2005 (UTC)
  • Does it move? It appears to be still on my screen. BrokenSegue 14:22, 22 Mar 2005 (UTC)
    • Ayup. Do you have gif animation disabled in your browser? —Korath (Talk) 15:19, Mar 22, 2005 (UTC)
  • comment After reading the comments above, I have created another version with four discs. I dont see this as a replacement for this one. It is more like an extension, because the colors of the upper three discs are the same, which shows the recursive nature of this solution. Now I'm waiting for comments asking for a version with 7 discs :) .. (please keep in mind that you need 2^(number of discs)-1 steps for the solution and most of them require two to four frames) -- Aka 19:45, 22 Mar 2005 (UTC)
    • I don't think seven is quite necessary. (Though if you could do a version with 64...) —Korath (Talk) 20:06, Mar 22, 2005 (UTC)
      • Hey, with full SVG support, 64 would be doable; the user gets to wait for it to finish and find out whether there are world-ending graphics. --Andrew 05:32, Mar 23, 2005 (UTC)
  • Support the four-disk version as FPC, although viewing the two side-by-side is quite compelling. -- Seth Ilys 21:02, 22 Mar 2005 (UTC)
  • Support four-disc version (though side-by-side does, indeed, look "quite compelling" in demonstrating recursiveness). James F. (talk) 23:06, 22 Mar 2005 (UTC)
  • Well, strongly oppose. The rendering is too sophisticated for the subject. Most importantly, it lacks smoothness, so it is hard to look at. If the goal is too illustrate the strategy for the Tower of Hanoi, then something simpler would be sufficient. We could put more frames in the animation without the file becoming too large. If the goal is to illustrate lighting and soft shadows, the image has nothing exceptional. --Bernard Helmstetter 00:41, 23 Mar 2005 (UTC)
  • Support either, but especially the 4 disk version. Spangineer 01:26, Mar 23, 2005 (UTC)
  • Neutral. I like the idea: it's a nice illustration of the solution method (bonus points if you create one using the non-recursive solution (color disks alternating black and white and add the rule that two disks of the same color may not touch)) but the graphics are more elaborate than necessary and the animation is somewhat distractingly jerky - a fine illustration, but not necessarily featured quality. --Andrew 05:32, Mar 23, 2005 (UTC)
  • Oppose. There is no indication of position... no "pegs". And the four disc version is grainy over the three disc version. -- AllyUnion (talk) 06:07, 23 Mar 2005 (UTC)
    • Considering the pic is a gif (otherwise no animation is possible) with complex color gradients, some graininess is to be expected. Circeus 16:40, Mar 28, 2005 (UTC)
  • Support four-disc version. Mark1 02:53, 24 Mar 2005 (UTC)
  • Support 4 disc version Leonardo 21:24, 2 Apr 2005 (UTC)
    • Overwhelming support, 4 disc version promoted. --brian0918™ 23:23, 3 Apr 2005 (UTC)
