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
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!
Hi, thanks for the comment! There is a second video where I explain how to make a legitimate 4d, not just an extrusion. It’s possible to make an approximation of a curve with this method: ruclips.net/video/TGX9pJ_lQ2A/видео.htmlsi=qPuR_0_8senfrxH0
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!]
@@glebmicnovic3813 ooh thank you, I can't wait to follow the tutorial when I'm at my laptop and also it would be cool if there were a way to extrude multiple times and change the scale so like making a pentachoron or a hypersphere with multiple extrusions
@@glebmicnovic3813 Oh cool, I was gonna say if you could turn an animation into an object that would be cool too like with the boolean modifier being animated but idk how that would work. 👍
literally the most underrated thing in the world
Thank you!
but is there a way to make it so that it can rotate in every z direction?@@glebmicnovic3813
i love this thank you very much
This is exactly what I was looking for! So far the only good tutorial I found on 4D objects in geonodes.
I’m glad it was helpful! There is also a part 2 on my channel
absolutely amazing brosky
Great video! I'm pretty sure you can still use the build in blender rotation node by doing something like this:

- 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.

It's interesting! You're right. As I understand, we "extend" Blender's 3x3 rotation matrix with this trick, in some sense
Dude this is absolutely amazing
Thanks!

@@glebmicnovic3813Oh nice!
[If you got confused, I was just commenting on how nightmarish a realistic 4d monkey would be to make.]
Dude this is insane thank you so much
I am glad!
Very informative!
when you think you are pretty good at blender and math then this man come in
currently trying to replicate it, it doesn't seem to work on modern blender
18:42 what happens if wireframe modifier isn't applied? Will this 4D animation work without wireframe modifier, like with just normal polygons?
17:17 The geometry will look like this, with solid faces. You can make a semi-transparent material to see everything
That was actually really fun to make! Why does it glitch like that someties when rotating?
I'm glad! It glitches because of the wireframe modifier. The modifier gives a thickness to the edges and it looks strange sometimes
@@glebmicnovic3813 Ok. Thanks!
👏👏👏

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
I created a group from a node. Press Ctrl+G or select Node > Make group. It automatically opens the new group.
@@glebmicnovic3813 Ohhhh thank you, I don't rly know the keybinds on blender but thanks for helping
This is literally sorcery
Is there a way to get this as an addon?
It's really cool though
@@TomtheMagician21 Yes, I will upload it. I will upload the second video soon and link it in the description
