      The important thing to realize about rotations in n dimensions, is that the "basic" rotations *always* rotate within a plane.
      That is, there is a plane of rotation.
      There *is* still an "axis," but its dimension is n-2, so
      In two dimensions, n=2, the axis is a point.
      In n=3, the axis is a line.
      In n=4, the axis is a plane.
      Etc.
      In linear-algebra-speak, it is the invariant subspace of the rotation; the set of vectors that are invariant under the rotation.

  • @Bunny99s
    @Bunny99s 6 років тому +272

    People always get the concept of rotation wrong ^^. The fact that a rotation is around an "axis" is only true for 3d, no other dimension has this link. You don't have the concept of a rotation axis in 2d without using the 3rd dimension as helper. Rotations actually happens in 2d rotation planes. The 2d space only has one plane, the 2d space itself. 3d has exactly 3 planes. A 2d plane in 3d has exactly one normal vector. However in 4d we have 6 rotation planes and each 2d plane has two normal vectors. It's basically just the number of combinations you can make from the component count. In 3d it's XY, XZ. YZ. In 4d it's XY, XZ, XW, YZ, YW, ZW. Any rotation in 3d is a "single" rotation. So even you rotate in several planes at the same time you always get a single rotation within a rotated plane (where the normal is the rotation axis). In 4d you can actually have double rotations that are independet from each other. Keep in mind a rotation matrix only changes the coorindates where the sin and cos are. Every "1" in a rotation matrix means that this dimension stays unchanged. In 4d you have two "1s". So a double rotation would be a combination where you exchange the two 1s with another rotation. So (XY and ZW) or (XZ and YW) or (XW and YZ). This gets more complex when dealing with 5d (10 rotation planes), 6d (15 rotation planes) or 7d (21 rotation planes).
    btw: Doing a double perspective projection and only from the center of an object is a rather arbitrary choice for projecting 4d into 2d. Keep in mind that you can also offset (move) 4d objects in 4 different directions. Usually in 3d we work with homogeneous coordinates to allow translation to be applied through a matrix. Though that means we actually use 4d vectors and 4x4 matrices for ordinary 3d. Lifting that up one dimension we actually need a 5x5 matrix and 5d vectors to do proper 4d stuff. This is important since the power of matrices lies in the fact that you can simply combine them into one. So you finally have a single matrix that does all sorts of local space rotation, position offsets, projecting down to 3d as a single matrix. Successive perspective projections can't be done as the perspective divide can't be performed in a matrix. It's done by the homogeneous divide at the end.
    4d (or higher dimensions in general) is / are really fascinating. It gives you a new way of thinking of fundamental measures.
    "0d" you only have a single point with no size and no location since the whole space is just a single point. Therefore an "object" in 0d doesn't require any components in a vector to describe that object.
    "1d" space consists of infinitely points in a single direction. Now a new measure is born: length. The length between two points in 1d is the sum of infinitely many points between the start and end point.
    "2d" space consists of infinitely many "1d spaces" stacked next to each other. We get a second independent direction and a new measure: "area". A finite area is the sum of infinitely many 2d lines which each contains infinitely many points. So points squared (p^2)
    "3d" space consists of infinitely many "2d spaces" stacked next to each other. Again a new independent direction is used here. The new measure is "3d volume". A finite 3d volume contains infinitely many finite 2s spaces which contains infinitely many 1d spaces which contains infinitely many points (p^3)
    "4d" space consists of infinitely many 3d spaces stacked next to each other in a new independent direction. The new measure is "4d volume". A finite 4d volume contains infinitely many finite 3d volumes. (p^4)
    The 8 3d cubes which represent the boundary of the 4d volume are just the "surface" of the 4d volume. Inside a tesseract there is infinitely 3d volume, just like in a 3d solid cube there is infinitely many area if you could chop up the 3d volume into infinitely many slices. Note that the sum of 3d space inside a 4d volume is non overlapping. So inside a 1x1x1 4d cube there would be enough 3d space to hold our entire universe :P though, just statistically. We have a continous 3d space. The 3d space inside a 4d hypercube is folded in a weird way.

  • @zarblitz

    Seeing this years late. Anyway what helped me understand how a tesseract is a projection of 4D space into 3D space, is to stare at your projection of a 3D cube into 2D space (the screen), and watch the points and planes change shape as it rotates. Watch how the trapezoid that represents one of the sides flattens as we start to view it "edge on", and watch how they intersect each other in 2D space. We know that intersection is an artifact of the projection into a lower dimension, just like the mind-bending intersections of a tesseract are an artifact of its projection into 3D (or really into a 2D representation of 3D). Try to break the illusion of it being 3D and see how the projection itself changes shape. Once I started to see it that way, looking at a projection of a 4D shape I better understood it as a projection, and stopped trying to see it in 3D.

    I don't know if you're going to see this, but the issue you had with returning p4vec vs pvec could have been solved using generics (specifically, make the return type T, and have the function take an type as input), and would probably be a new concept to a lot of your viewers. When I first figured that out, I was able to delete a ton of duplicate code from my projects.

    Thanks for that wonderful train ride!
    To me, the next interesting thing to do is to make some other 4D shapes and subject them to these same 4D rotations.
    There are, e.g., 6 regular polytopes (hypersolids) in 4D, of which the tesseract is just one. Some important attributes of these, are the numbers of vertices, V, edges, E, faces, F, and cells, C (3D faces). I'll put these into a 4-list: (V, E, F, C).
    The simplest one (which is the 4D edition of a simplex), is the regular pentatope, or tetrahedral pyramid. It makes the least interesting model for this, but it's still worth portraying; it's analogous to the tetrahedron; its cells are tetrahedra. It has (V, E, F, C) = (5, 10, 10, 5).
    Then there's the hypercube; tesseract; analogous to the cube; its cells are cubes. (V, E, F, C) = (16, 32, 24, 8)
    Next is the "dual" of the hypercube, the cross-polytope; 16-cell; analogous to the octahedron; its cells are tetrahedra. (V, E, F, C) = (8, 24, 32, 16)
    Then perhaps the most interesting, the "hyperdiamond;" 24-cell; not analogous to anything else in any number of dimensions; its cells are octahedra.
    (V, E, F, C) = (24, 96, 96, 24)
    The last two are really complex & cluttered, but fascinating nonetheless:
    The 120-cell; analogous to the dodecahedron; its cells are dodecahedra. (V, E, F, C) = (600, 1200, 720, 120)
    The 600-cell; analogous to the icosahedron; its cells are tetrahedra. (V, E, F, C) = (120, 720, 1200, 600)
    And there are plenty of other interesting polytopes; in 4D you can "cross" one polygon with another; e.g., square x square = hypercube.
    What this operation amounts to is, at every point (both boundary & interior!) of polygon #1 in xy-space, you erect polygon #2 in zw-space.
    The result has somewhat of a "hypertorus" feel to it.

    Connections:
    - Do the loop from i=0-N and connect i to i+N (the last 3 lines you have now)
    - If N > 1:
    - Divide N by 2
    - Recurse into each half

    36:53 : Actually, as I understand, we are usually rotating 2 dimensions (at least beacouse we can't rotate in 0 or 1D), not around one dimension ( or we can say we're rotating around all other dimensions. Infinity of them... So it's unreasonable)

    • @ShevkoMore

      there's built in library support for VR in processing (see android.processing.org/tutorials/vr_intro/index.html), if you have a VR headset and have watched a lot of the videos on this channel for some time, shouldn't be that hard to implement this yourself on top of what he did in this video

    What if gravity is actualy 4th dimension? Or consequence of 4D because it is pushing space similar to X and W rotation? Also kind of proves we could create wormhole?

    When you render 3D objects on 2D screen you have to, well, fit in 2D space so it gets chopped down, with 4D figures it gets cut even further. I wonder how would 4d objects look like in 3d space from for example laser visualisation, would this make rotating on W axis more clear?
