This looks like a fever dream

👏👏👏

i love this thank you very much

currently trying to replicate it, it doesn't seem to work on modern blender

I get sort of whats going on, and I understand 4d sort of, and how it's X,Y,Z, but add a W, and for each W, is a XYZ, which I can understand and visualize, but I don't get any of the weird animation bits and peices with the shapes. I might be veiwing it wrong, or something. I want to learn though, and It would be cool to make a 4d objects, but I don't understand the underlining properties of 4d objects. I feel like i'm only at the tip of this 4d iceberg. is it rotating through 3d slices of 4d causing the weird animation? what all should be visible and invisible? would a tesseract make better since if not all of it was visible? I've seen the math and understand it.... sort of..... but I'ts still very confusing. When I see a 3d sphere passing through a 2d plane, I understand it, and I understand say I hypersphere passing through a slice of 3d in a 4d world, where it increases and decreases in size but seeing objects do weird flippy floppy inside out things is confusing.

Dude this is absolutely amazing

That was actually really fun to make! Why does it glitch like that someties when rotating?

absolutely amazing brosky

Dude this is insane thank you so much

Does the monkey look like it's going inside out to you? [With the tesseract that's reasonable but for the monkey it sure as hell doesn't look like it's going "inside out" to me, it just looks like it's rotating, so I assume those comments some 4d videos get are just spam. Tk, great video!]

0:19, Y'know what they say, be there or be eldritch demon prism! [But seriously a legitimate 4d extension of the monkey instead of just an extrusion would be a f'king nightmare to make. By the way, are there actually any classical constructions of 4d curves?, that would be interesting to see.] I know this is already a pretty long comment, but I feel like this would benefit from some kind of special ray tracing (although that might be hard to make). While the monkey.. thing? looks reasonably like it's being rotated, the other ones look a little bit flat. Other than that it's a great video! Thank you!

This is literally sorcery

This looks so cool!

Amazing!

nice!!

literally the most underrated thing in the world

this is so much underated

when you think you are pretty good at blender and math then this man come in

This is exactly what I was looking for! So far the only good tutorial I found on 4D objects in geonodes.

Surrounded by a higher dimensional cube in a VR360.. this movie only has one frame.. you move to see different angles.. made with blender too 0001 0030 L injected ruclips.net/user/shortsMW8r2rrSG-0?feature=share

Epico, I might make a compilation of mine but I'd have to render them first

For those wanting to do non wireframe renders and noticing there is a missing cell,there is a simple fix for that.Copy the rotation and projection nodes,put the original non-extruded geometry as input and set W to 1.Then join geometry to the rest of the geometry before going into set position. This ONLY works for simple extrusions and extrusion +scale!

interesting method.I've played with the node setup from the previous tutorial and there is a easier way to make a 5-cell(and any other 4d pyramind for that matter).Put a scale elements node between extrude and set position and set scale to 0(any value inbetween gives a truncated pyramid).Another cool method to make 4d object is using the parametric equations.I've made some really cool duoprisms,klein bottles and toripshere renders. you can also duplicate the geometry at different positions along W and with different rotation to do stuff like 4D Rubik's cubes.For those wanting to see some of the stuff i've made there is a video on my channel.

you could if done right store 3d rig animations in a 4d model Cx

What did you do at 6:42? I can't track what happened when the screen changed

Is there a way to get this as an addon?

18:42 what happens if wireframe modifier isn't applied? Will this 4D animation work without wireframe modifier, like with just normal polygons?

Great video! I'm pretty sure you can still use the build in blender rotation node by doing something like this: - Separate XYZ the "vector" input gives x y and z - Combine XYZ with x z and w as inputs - Rotate node with the vector from the combine xyz as input. Set mode to rotate X to get the same rotation as in the video - Separate XYZ the output of the rotate node. The "z" output is "w" - Combine XYZ with the "x" of the separate as the "x" coord, the original "y" as the "y" coord, and the "y" of the separate xyz as the "z" coord. This way you just get a rotation which fixes the x and y coordinates and just rotates the z and w coords. Hope that was clear. Just an idea I had and trying to be helpful. Doing the matrix multiplication manually teaches you more about what is happening of course

Very informative!
