4D Toys Update: Rotating the 3D Slice, Face Projections, Marble scenes + Every new feature

And when the universe needed him the most, he returned

I just redownloaded 4d toys yesterday to show a friend (we're both math grad students, and he said you "can't visualize" 4d - I wanted to show him this because it is the best tool I've used to help me understand 4d intuitively). So excited for these updates!

[MuzikBike]

One thing I'd like to see is an expansion of the "2D slices of 3D shapes" examples. For example, if we take an octahedron in 3D and take sequential 2D slices of it vertex-first, we have a square that grows from a point to its maximum size and shrinks back to a point again, but a face-first slicing reveals a triangle that morphs into its own dual through a hexagonal path. Both of these "types" of octahedra can be seen in the 24-cell. I think that providing more 3D shapes to slice up in 2D would invite people to better understand why certain 3D slices of 4D shapes look the way they do.

Wasn't expecting to see this in my notifications. What a pleasant surprise! I'm glad you're still doing your thing!

[andriypredmyrskyy]

I just wanted you to know that I care a lot about stuff like this. I loved getting an intuition for a dimension I'll never visit, but also actually being able to visit it.

Know that if I can, and if I know I can, me and countless other math lovers will support you.

0:48 I almost expected that thing to warp when you rolled it.

[TheThursty]

This will be legit the first patreon I'll subscribe too.

I've been looking forward to miegakure for so so long, glad to see it's still being worked on

This 4D Stuff is truely inspiring for me thank you very much!

[aarocka]

I remember seeing your booth at PAX East 2013. Are you ever going to release the Miegakure demo? It was really fun. I would gladly contribute to the patreon if I could get the demo.

[bluestaggo]

HE'S I believe you are the one who got me into 4D, and now you are at it again!

[FireyDeath]

Well that came out of nowhere

Great additions

[StaticGeek]

Coding 4d collisions and physics must be painful but it gives really cool results

[MAbdusson]

After all these years I'm following you and your projects you still amaze me. Keep up the good work!

[ReFreezed]

I'm always happy to see news on the 4D stuff you're working on. Even after all these years, I'm still excited to one day play Miegakure.

[nemesisurvivorleon]

Yes I got 4D toys. I may not spend a ton of time on it but I love it sooo much. Thank you for making it exist!

[zamarion]

Any chance we ever get a miegakure release :c? Even just whatever you have if you dont wanna fully complete it

[marcusscience]

Suggestion: add the Clifford torus, the 4 dimensional isometric embedding of the 2-torus with zero Gaussian curvature at every point.

[whoeveriamiam]

nice that you're still working on it. I really liked the toy box but it was lacking some features which you have now added

[archbox]

Awesome!!! :) I'm eagerly waiting for miegakure :D keep it up! Plus all the extra features you have added to 4D Toys are really nice :) I once wrote you a mail about having multiple slice views at once but switching is also not bad, however seeing two perspectives at once while playing with the objects could also be fun :D Anyways I hope you have fun building all that stuff and seeing the interactions from the community :D When Miegakure comes out I will insta buy it! :D Cheers!

I just bought the app, thank you for finally fulfilling my dream of visualising the spatial transitions between 3D and 4d. 🎉
