The code is a real mess of mine rescued from who knows when. Retouched 
for this gruesome animation of 450 frames where the changing color 
tetrahedra "guessed right" to change their pigment in the first test.

My apologies for using an automatic translator. After watching a series 
of videos on YouTube with the differences between English from the 
United Kingdom, India, the United States and Australia, I only know that 
I do not know what language I am abusing right now.

Regards.

Very nice  :)
It's always good to see a new (for us) piece presented, especially in an
animation.

I always like your color schemes and lighting.  The partially transparent
textures (and probably high radiosity settings) must make rendering a 450-frame
animation an extensive project!  :O

Being a fan of projective geometry, I wish there were shadows, but that would
make it take even longer, I'm sure.  ;)



Great work as usual - you should run this by Vi Hart - this kind of thing is
right up her alley, and we might entice someone new to join the POV-Ray
community.  :)   She might even take up the challenge to render and animate a
hexaflexagon...   :D

Hi, Thank you. No radiosity settings this time. With some filling lights 
and 4 instances of povray launched simultanously takes 1 hour more or 
less in my Intel® Core™ i7-3770 CPU @ 3.40GHz × 8 running Ubuntu 18.04.1 
LTS.

I've doing some maths and adjustments to the shape of the tetrahedrons.

The code and ini files that i'm running right now are included on a zip 
file. No warranty at all.

On queue.

Just the kind of stuff that my procrastinating anxiety was jelling me 
about. :-p

S0rry, looks like a zip file is a better idea

I kinda liked them inline.  I'm not interested in downloading your code
but I did like quickly reading it.

Intriguing! May I video-grab, convert this to Atari ST and Commodore 64 
graphic modes and re-publish it on my YouTube channel, of course 
crediting you and linking to the original? What about your other animations?

See you in Khyberspace!

If I do not want someone to think, modify or create from what I do, I 
would stay under my table growling. Which on the other hand is what I do 
most of the time. My point of view is this. The code is published in 
this thread, the video in instagram. Do with it something beautiful and 
creative, but do not give me credits that I do not deserve. Maybe Tom 
Hull for his paper instructions, maybe Mr. H Martin Cundy and A P 
Rollett. Or Plato?

I do not know if in the English translation I look silly, funny or 
sarcastic. It's just a message written quickly and running, 
half-expressing what I do not know how to express in Spanish. Maybe I 
wanted to say yes, that for my part you can take without crediting the 
source and do what you want with it, in which case someone (with a lot 
of free time) could accuse you of plagiarism. Or credit me with 
authorship, in which case I will cover myself with glory, fame and shame 
for plagiarism. What a moral dilemma of s***.

Pd. Here some old friends to divert the subject and close this absurd 
conversation with myself.
