Title: Geometer's sketchpad Post by: Lee Oliver on September 20, 2010, 09:42:24 PM Some of you may or may not know about Geometer's sketchpad so I will introduce it here. It is mostly used for general [euclidean] Geometry, but it can be applied to make simple fractal patterns. It is how I started making fractals, and I still use it during my lunch break.
Here is a link to the main site: http://www.dynamicgeometry.com/ Unfortunately it is not a freeware program so it does cost a pretty penny. I myself only have access to it at school. I will post a few of my images tomorrow because it doesn't save images as jpgs. I will also post a little something I found recently. :whistle2: Title: Re: Geometer's sketchpad Post by: Lee Oliver on September 21, 2010, 09:42:19 PM I converted all of my images to jpgs today so here is a small sample:
(http://i763.photobucket.com/albums/xx278/BrutalToad/SierpinskiSquig.jpg) (http://i763.photobucket.com/albums/xx278/BrutalToad/Muffin.jpg) (http://i763.photobucket.com/albums/xx278/BrutalToad/Leaves.jpg) (http://i763.photobucket.com/albums/xx278/BrutalToad/Hindu.jpg) (http://i763.photobucket.com/albums/xx278/BrutalToad/Dragon2.jpg) (http://i763.photobucket.com/albums/xx278/BrutalToad/Dragon1.jpg) (http://i763.photobucket.com/albums/xx278/BrutalToad/Circle.jpg) (http://i763.photobucket.com/albums/xx278/BrutalToad/Yggdrasil.jpg) I made many of these with a common initiator shape, which is the point of this post. I call it the dragon box. In stead of finding new initiators to construct different dragons, I just use this box, which should include most of the dragons' initiators. I was wondering if this could be extended through three dimensions to create 3D dragon fractals, does anyone know any methods for doing such a thing? (http://i763.photobucket.com/albums/xx278/BrutalToad/DragonBox.jpg) This is a very rudimentary program for creating fractals, but it is fun to mess with. :) P.S. Do you like my muffin fractal? :) Title: Re: Geometer's sketchpad Post by: bib on September 21, 2010, 10:58:29 PM (http://i763.photobucket.com/albums/xx278/BrutalToad/Muffin.jpg) My favorite "hand drawn" fractal, and especially the one that brought me to this forum: http://www.fractalforums.com/meet-and-greet/have-you-seen-this-fractal/msg6070/#msg6070 But I wouldn't try to eat your spiky muffin! :) Title: Re: Geometer's sketchpad Post by: Thunderwave on September 21, 2010, 11:25:13 PM It's toadstool! :)

Yes as was said in the link to your picture, it is a Levy dragon. All of the fractals in Geo Sketchpad have that hand-drawn quality to them.

Yes as was said in the link to your picture, it is a Levy dragon. All of the fractals in Geo Sketchpad have that hand-drawn quality to them. In fact I really drew it by hand on a wall in a friends room 15 years ago, but it's been painted over. It was 1 meter big. I don't remember the number of iterations, maybe 7 or 8, so the final bits were really small, less than 0,5 cm. It took me maybe 20 hours or more. I was young and stupid, but I had found a method to draw it very easily, it was really automatic for me :) Title: Re: Geometer's sketchpad Post by: jehovajah on October 10, 2010, 06:03:55 AM Google Sketchup (http://sketchup.google.com/intl/en/training/videos/new_to_gsu.html) may be useful to you.
