Hi all,
First of all, best wishes to everyone for 2022! It has been a while, but I found
some time to work with POV-Ray again, and the result is another puzzle
animation.
The basis is a twelve part puzzle designed by Yukio Hirose. Once I realised that
the design could be extended in a fractal-like fashion, I figured it would make
an excellent animation subject.
The textures are very basic. They are designed to show off the puzzle's
structure. However, the animation has some interesting technical features.
First, the part movement of the Level 2 assembly requires moving 144 parts. To
move as many parts in parallel without any parts colliding, a greedy scheduling
algorithm is used together with a basic collision detection algorithm.
Second, for in-flight part rotations I had a go at using Quaternions. I used
an old quaternions.inc file
(http://news.povray.org/povray.binaries.scene-files/thread/%3CXns940C86DC9B1D4None%40204.213.191.226%3E/)
as starting point. It was a good start, but I had to fix a few bugs. The updated
file can be found on GitHub, alongside all other source code used to create the
animation:
https://github.com/erwinbonsma/HoleyCubeAnimation
Anyway, enough talk. Here's the link to the video:

I hope you like it!
Cheers,
Erwin

Yes, I like it, well done.
Going to github later and see you did all this.
Cheers
Ton.

Wow - that's ambitious, in and of itself!

But of course you did! ;)
Next we know, you'll be into Octonions and hanging out with Cohl Furey...

Wow - as if the earlier puzzle videos weren't impressive enough - now you have
everything dancing and oscillating with the musical score...
.... and of course you had to expand on the original puzzle so that it could be
fractally extended out to infinity.
What's next? 4D puzzles?
Great job as always - glad to see a new puzzle, and one that is impressive on so
many levels as well :)
- Bill

Holey shit! You will be fined 100 Credits, sir, for dancing in a
confined spaced during Covid lockdown! You should be ashamed of
yourself, exposing all those innocent pieces to serious contamination,
not the least being to want to start all over again watching the video!
One of your best assuredly. I seriously wonder how you could keep track
of all those pieces moving at the same time.

Happy new year as well!
What an accomplishment - the technical features are impressive indeed.
Have a great day,
Dave Blandston
