Your next game dice can be in the shape of a dragon or tatou

The algorithm analyzed a design in the shape of a torus similar to the old joints.

So, one day soon, players could choose from a wide selection of exotic form dice for the future game – and even 3D print their own creations. (You can already print in 3D the conceptions of the team from Baktash Posted the STL files.) The new tool can also be useful for creating arrangements of natural appearance of geometry or adjusting a design so that an object is better able to stand up, similar to “Daruma Doll“A traditional hollow and weighted Japanese toy at the bottom so that it always returns to a vertical position when it is tilted.” Our approach makes it possible to cook this property in the geometry of the form itself, “said Crane.

As for more “serious” applications, the crane points to underwater construction “, where the low content hypothesis is very realistic and it is important that things land in the right orientation,” he said. “Alternatively, if you imagine that each small grain of sand or earth is a rigid particle, the statistics of the way they land could help understand things like the soil was enjoyed and compact. The exciting thing about research like this in the world is that, a few years later, other people inevitably find cases of use for that we could never imagine.”

There are inevitable compromises. Mathematician of Oklahoma State University Henry Segerman said to the new scientist That the method is not “necessarily a solution of money to conceive of strange dice, because it ignores friction, the rebound and other momentum effects of the real world. It is more as if they are – very effectively – practicing where a matrix is ​​found if you place it with a random orientation on an unlisted surface in low gravity.

Crane and his co-authors recognize as much in their article. “On the one hand, [critics] are absolutely right that our model does not make perfect predictions from the point of view of idealized geometry and physics, “said Crane.” On the other hand, if your goal is to literally do dice for table games, it is perfectly reasonable to do this type of approximations. “”
