[@ASaltyAcc]

I’m trying to understand how they coded the correct solutions, it seems simple from an outside point but that looks like hell to code.

[@5alpha23]

@@ASaltyAcc that's really easy actually: each transformation is a matrix, multiple transformations is just a matrix multiplication. The desired shape (i.e. an equation with three variables) has a "solution matrix" attached and you compare the two (solution vs. user created). For the general shape you check if certain values are zero, positive or negative and then you just state an error for each of the fields that a user is allowed to be off. 🤷 Rotating or moving the user shape changes the transformation matrix as well of course. I find it more fascinating that we're at a processing power that allows this to be calculated on the fly 😉

[@Phriedah]

I can't tell if topologists would love or hate this game

[@ethanbottomley-mason8447]

@@Phriedah It shows some nice homeomorphisms and continuous transformations. I wouldn't say it really helps with learning topology beyond imparting the idea that you only care about shapes up to homeomorphism, i.e. if one shape can be continuously changed into the other and the other can be continuous changed back, then they are the same. When properly learning basic topology, it is a lot of manipulating sets and functions rather than looking at shapes. Understanding the shapes and spaces you are working with is important, as you are able to intuitively guess at the properties of those spaces without having to do actual computations, however if you want to prove things, you actually do have to do computations.

[@mujtabaalam5907]

​@@ethanbottomley-mason8447 But in this game you can change a sheet into a torus or a sphere. I don't think those are homeomorphic, are they?

[@ethanbottomley-mason8447]

@@mujtabaalam5907 Indeed, they are not homeomorphic. The fundamental group of a sphere is trivial and the fundamental group of a torus is Z * Z. This is because the polar coordinate transformation is not a homeomorphism but rather just a continuous map. It is a homeomorphism from (0,2pi] x (0, infty) to R^2-{0}.

Tyler’s really like : “ah yes I see the checkers alight to form this demented geometry which I may manipulate based on the X and y axis and move between dimensions” Then also have his : “:0 whAt AboUT tHiS APpLe?” moments

[@ChristianOudard]

"I wonder how the algorithm for close enough works?" I expect that it's using a parameter space where each coefficient is for x-stretch, y-stretch, amount of sine-wave, amount of curvature around a cylinder, etc. So we would get a list of numbers that describes exactly the transformations that the surface has undergone. We can define distance in this parameter space via the euclidean metric (sqrt(a^2 + b^2 + c^2 ...)). Then there's just a threshold *parameter* distance that counts as success.

[@Khaim.m]

I don't know if that would work for different solutions, and there definitely are multiple sets of transformations which produce the same result. Or maybe it would? I guess it's probably all matrices so on second thought yeah, it's probably a metric on the matrix representation.

[@NStripleseven]

I suspect that the transformations don’t quite commute, so a simple parameter space wouldn’t really be possible. Can’t prove it though.

[@blockmath_2048]

I think it's more of a mesh volume comparison. It tries a bunch of relative positions, and scores them based on how "close" a kind of voxel building the mesh are to the target.

[@QuantumConundrum]

Pretty sure it's a mesh approach since to have commute property you'd need a mirror operation?

This game implicitly teaches you different coordinate systems and transformations. Actually used a lot in physics.

[@kingacrisius]

Like another guy said, this game has felt pretty easy to me so far, likely due to my use of 3D modeling software. The only parts that have been strange to me are the wavy line thing, as that is not generally a feature of 3D modeling programs. The stretched one is, well, stretching, and the circle one is the revolve tool. To me it was pretty intuitive in most of the ones using a circle what you needed to put in to get the object, same with turning it diagonally once you got the squiggly shape. The only parts that have been confusing me are the squiggles themself, very hard for me to visualize what it's going to look like.

If I had to guess as to how the forgiveness factor worked, I'd wager that each available transform is just a matrix (linear algebra). Where you place the shape on these transforms adjusts the values used by the transform. Finally, it sees if each component of your matrix is close enough to the solution. Matrix transformations are dependent on the order you do them.

[@stickmanonastick6089]

An alternate way to think about the circle transformation is that each horizontal row on the checkerboard becomes a ring on the circle board. This explains why horizontal objects get wrapped around to make a circular shape.
