These images have inspired me to create a program which simulates the patterns in them based on the following user inputted modifiers: number of circles, circle speed multiplier, circle size divisor, and circle direction (same or opposite). I have only created this program for individual educational purposes and will give you full credit when submitting it to my teacher.<br /><br />I have had no trouble creating this program, but at this point I would like to display the parametric equations of the pattern based on the user inputted modifiers. Is there any general parametric equation based on the inputted modifiers which can model these patterns?<br />Thank you in advance, <br />JonathanSabayonCompizhttps://www.blogger.com/profile/10614479577305830965noreply@blogger.comtag:blogger.com,1999:blog-2261985361614499342.post-5198042607825975292014-06-29T17:51:35.535-07:002014-06-29T17:51:35.535-07:00You can ask questions here.You can ask questions here.benicehttps://www.blogger.com/profile/09841851785144902423noreply@blogger.comtag:blogger.com,1999:blog-2261985361614499342.post-8716700878795734232014-06-29T17:45:36.994-07:002014-06-29T17:45:36.994-07:0010 (or 11) circles for the first dynamic image and...10 (or 11) circles for the first dynamic image and 100 (or 101) circles for the first static image.benicehttps://www.blogger.com/profile/09841851785144902423noreply@blogger.comtag:blogger.com,1999:blog-2261985361614499342.post-49913233428914794632014-06-21T05:23:58.580-07:002014-06-21T05:23:58.580-07:00Do you have skype or something, so I can contact y...Do you have skype or something, so I can contact you because I have some questions ;)Nimolohttp://www.nimolo.comnoreply@blogger.comtag:blogger.com,1999:blog-2261985361614499342.post-29934984986046214902014-06-21T04:47:06.821-07:002014-06-21T04:47:06.821-07:00How many circles are there in the first image ?How many circles are there in the first image ?Nimolohttp://www.nimolo.comnoreply@blogger.comtag:blogger.com,1999:blog-2261985361614499342.post-77941482260238438172012-02-16T13:35:22.665-08:002012-02-16T13:35:22.665-08:00Speed(n) = k^(n-1), k=±2, ±3, ±4, ....Speed(n) = k^(n-1), k=±2, ±3, ±4, ....benicehttps://www.blogger.com/profile/09841851785144902423noreply@blogger.comtag:blogger.com,1999:blog-2261985361614499342.post-88350626973455092982012-02-14T23:51:45.902-08:002012-02-14T23:51:45.902-08:00Do you choose the speed of spinning randomly and s...Do you choose the speed of spinning randomly and see what will happen or you chose them for a reason? :-)Boulayohttps://www.blogger.com/profile/14716545644928360577noreply@blogger.comtag:blogger.com,1999:blog-2261985361614499342.post-89195579355609695412012-01-30T17:09:22.865-08:002012-01-30T17:09:22.865-08:00The 5th looks most like a snow-flake!
