Hi,

I have just finished my latest puzzle animation and the last one for this year.
It features the Frankenstein puzzle designed by Alfons Eyckmans. This is an
18-piece burr puzzle with an irregular but beautiful structure. The two
contrasting woods help to show off the puzzle's shape.

This is another difficult puzzle. It has level 25.15.7.19.3.6, which means it
takes 25 moves to release the first piece, another fifteen to release the
second, and so on. I spent several evenings just trying to disassemble it.

You can see what the puzzle looks like in the attached image.
The animation can be found on YouTube at https://youtu.be/m1-XLITijPI

I hope you like it.

Cheers,
Erwin

Hey,
I notice your wood grains ... I suffer with mine, they sparkle as I 
animate them. Can you post or send me your textures?  I'm curious what 
you do different. (I'm more into a maple flavor, than cherry or birch :) )

thanks

Assembling such a puzzle is definitely more difficult than taking it apart. In
fact, it is practically impossible without help of a computer or using notes
made while disassembling it. The latter is how I typically manage. These notes
also help during disassembly itself. The shape of each puzzle piece slowly
become clear, which may provide further hints on next steps in the disassembly
sequence. Furthermore, not unimportantly, making these notes also make your
progress more visible, which helps to keep up motivation. "Well, I may not have
solved the puzzle today yet, but at least I managed to get a bit further"

Attached my textures. There is nothing special about them. They are based on
textures from woods.inc, modified slightly to better resemble the woods of the
actual puzzle, in this case Movingi and Padouk. There's one trick, I use macros
to slightly darken the ends of the pieces by reducing the diffuse setting.

Maybe the sparkling you see is due to your anti-aliasing settings? Jitter should
be set to zero.

Cheers,
Erwin

And make sure that crand is not used.

Another astounding animation!

If solving real wooden puzzles like this was a general 'test of intelligence',
99.9 percent of us would fail miserably :-0

On your Youtube page, you mention that this puzzle can be constructed 'from a
single block of wood.' In POV-Ray, maybe! -- otherwise it would take
CONSIDERABLE skill with a hand saw (???!!) Is that a challenge that real-world
puzzle makers try to achieve when making such objects?

In your animations, have you ever tried making the pieces semi-transparent? It
would be fun to see how they move past each other during disassembly (but I can
imaging that it might be totally confusing, visually.)

Too true.

Hand saw? Scroll saw, surely.

That would look great but can you imagine what the max_trace_level would be?

I interpret the sentence on the YouTube page as saying that the /pieces/
can be crafted from a single piece of wood /each/ [without a chisel].

As clipka meanwhile also pointed out, the comment was with respect to the
individual puzzle pieces. For complex burr puzzles it is not unusual for some
pieces to be non-notchable, which means that a single puzzle piece needs to be
created by glueing multiple parts together.

Yes, I have. However, it can indeed be quite confusing. See the attached image.
The top shows Super Nova, where I used a wire frame and contrasting colours to
enable identification of the different pieces. The bottom shows Helix the Burr,
where the animation lets the X-Ray scan got from top to bottom and back. This
makes it clear what is happening at the boundary, but as you can see, overall
the result is quite confusing. But then again, it's not that surprising that 3D
information cannot be easily mapped to two dimensions.

It's always amazing that you're able to fully animate the entire solution
process with a computer...
