Either way, it produces a beautiful aesthetic. I'd love to play around with this idea.

Well except for this is SIM only whereas the OP (WillMor) is making them for real with a 3D printer!
My point was that these software could help to find weak parts in trajectory - so instead of trying to figure it out by looking where balls are too quick to fall from the ride - you can simulate it. I saw real tramway simulation done in Ansys.
This is a great example of a good use case for 3D printers. The smooth marble run action combined with the interwoven organic forms would be a huge PITA to fabricate with any other method I can think of, even if your just making one.
Beautiful, I wonder what kind of craziness would be possible with this, at scale. Whole buildings being printed and assembled block by block. Real life Minecraft, if you will
Blame! is a manga where in the future humans have robots that build, and are controlled by people with Net Terminal Genes. Something happens and those humans die leaving the robots building non-stop procedurally for eons. By the time our protagonist moves about in the world, its said the Megastructure reaches from Earth all the way to Jupiter. Also, the movie Fracture features these cool marble machines. https://www.…
Designers of marble fountains who don't use computing to design the paths run into reliability issues: sometimes balls derailing out of their track. They have to observe the contraption, identify problems (balls getting jammed up or jumping out) and then guess at the root causes and make manual adjustments. That's the thing here: he has it running for hours presumably without any ball jumping out. Most of the tracks…
You can see a ball on the ground at the end of the video :-)
Super cool! I would love to see a white / clear one with LEDs. Rainbow road :)

Where did they get the material for it?
Also conceivable that meteors etc crash into the megastructure providing it with endless resources.

It's actually much weirder than that: banking changes the axis of rotation and thus kills the rotational inertia. The tracks bank super aggressively in order to prevent the ball from accelerating too much and hopping the track. This is part of why the descent is so smooth and all the balls move at more or less the same speed. Also to be fair the final system does lose a ball every 30ish minutes. The tuning was largel…
I wish there was a write up of how some of the code works. There's a lot of Python in the repo. Looks fascinating, seems to use Python to generate OpenSCAD code, I think.
It's specifically using SolidPython2 to generate the models. I originally wanted to do a quick code cleanup and have the specific math be much clearer but by the time it was working that was an absolutely massive undertaking. If I touch the code again I'm probably going to refactor the entire codebase and use a different 3D engine.
