Bouncing Bucky Ball at Flipbook Mini Hack » Cleve’s Nook: Cleve Moler on Arithmetic and Computing

The 2023 MATLAB Central Flipbook Mini Hack contest runs from November 6 till December 3. Over 200 entries have been submitted within the first two weeks.


New Guidelines

This 12 months’s mini hack options brief animations. The competition software program runs this system you undergo make an animated GIF file with precisely 48 frames and an inner-frame delay time of 1/24 second. So, your animation will run for 2 seconds, then repeatedly repeat. If you need periodic movement, you must be again the place you began by body 48.

In earlier mini hacks, applications needed to be Twitter size — at most 255 characters lengthy. Now, the brand new restrict is 2,000 characters. Feedback and formatting blanks aren’t counted. Remixes and reuse of different submissions is inspired.

Members and different viewers vote on the submissions. There are prizes like Amazon reward playing cards and T-shirts. MathWorkers could take part, however not win prizes.

Private Favorites

I discover the outcomes fascinating. There are such a lot of completely different inventive types, inventive abilities and programming methods. Listed here are a couple of of my private favorites.

Jenny Bosten

Jenny Bosten is a well-known identify on MATLAB Central. She is a Senior Lecturer in Psychology on the College of Sussex, the place she is a “visible neuroscientist specialising in color imaginative and prescient.” Her code for Time lapse of Lake view to the West exhibits she can be a wizard of coordinate techniques and shade maps.

隆光 中村

I do not know something about this individual. All I see is that this identify, 隆光 中村, and this ingenious code for Fireworks.

Ned Gulley

Ned is the long-time MathWorker who’s the architect of MATLAB Central, and who, this time, can be a prolific participant. One in every of his extra mathematical animations is Orbiting Roots.

Eric Ludham

Eric is head of the MathWorks growth crew for Graphics and Charting. Contributions like this Blooming Rose show his inventive design expertise.

Bouncing Bucky Ball

My very own contributions aren’t almost as engaging as these.

The two,000 character restrict is a good suggestion. It pressured me to look critically at some outdated code and rewrite it to be easier and clearer.

This program for a Bouncing Bucky Ball makes use of the hgtransform object to good impact. I additionally assume it has a pleasant answer to the issue going through all people of the way to retain state from one body to the following.
