You can enhance the setting adjusting the texts positions and envetually give the texts some animation (scale up or down for instance). The images formed when the hypercube rotates in four-dimensional space resemble those of the ordinary cube rotating in three-space. If the rotation is not good, make vertex parent again but choose 3 other vertices. All four adjacent faces will rotate right angles, however two opposite adjacent faces will have opposite rotating directions otherwise, one of them will end in. To check that, animate the cube and look how the text behaves.
This parenting could give a good result, or not. Shift select the cube, so that the cube is active and the text still selected.Įnter edit mode, select 3 vertices of the plane the text is aligned to, and use Ctrl P to make vertex parent.

This is easier.įor the other ones that "rotate" on sides, vertex parenting is used. Download scientific diagram Rotated hypercube projected to 3D space by perspective projection from publication: LAMPSHADE DESIGN THAT TAKES ADVANTAGE OF. Each retina records a 3-dimensional image. The 4-dimensional person has a 3-dimensional retina in each of its 2 eyes (two eyes suffice for depth perception, even in 4D). Imagine a person who lives in 4 spatial dimensions, watching a hypercube rotate. This is the same principle:Įach of these 4 empties is hook (modifier) for the corresponding horizontal face of the 4d cube.įor the texts objects (that, again, could be planes with textures intead), I used two cases:įor the 4 horizontal planes, the texts are simply parented to the corresponding empties. Check out Mark Newbold’s Hyperspace Star Polytope Slicer. This could have been done with bones too. You are welcome to leave a comment to tell what you think.To avoid the texts to be stretched on the cube faces, you can use separate objects (either text objects or planes with textures and transparency) and parent them to the vertices of the cube:įor the cube animation, have used 4 empties that move up down and are scaled to simulate the 4d effect. So stay tuned, I will be posting some new Logo programs after I refined some language issues. And in fact, I have identified a few bugs and new ideas that I need to implement in VRMath2 Editor. Since the motion illustrated by a zoetrope must be periodic (or looped), we should restrict the rotation so that it appears less like a random tumble and more like a well-timed sequence of somersaults. My purpose of doing this hypercube is to test the CoordinateInterpolator for animation. Design and construct a 3D zoetrope which illustrates the shadow of a hypercube as it rotates in 4-dimensional space. Hypercube Vertices in Parallel Coordinates This is a four dimensional visualization of the vertices.
I have not yet to write teaching and learning ideas for this, but I think students will be interested in creating and programming, and at the same time learnt about 3D coordinate system and structure of cubes. Hypercube Edges in Orthogonal Projection Indices Edges Perspective Rotate xz Rotate yz Rotate xw Rotate yw Rotate xy Rotate zw Unfortunately, your browser does not support coolness. Only if you are interested, you can download and try the Logo program here: hypercube.logo.įrom doing this, the mathematical concepts about zero to n-dimension space can be explored. You can click on it to toggle the spin effect on and off. I have also added a small sphere at the center of the hypercube. You can see below how the 4D cube was created from 0-D point to 1-D line, to 2-D square, to 3-D cube, then to 4-D Tesseract. Beginning at the 1-minute mark, the film observes and annotates a rotating cube in three ways: orthogonal or straight projection, central or perspective. I tried in VRMath2 Editor to create a 4D cube. You may also study in more depth on Wikipedia, where you can find the mathematical n-dimensional hypercubes. One of the most famous 4D cubes is perhaps the 4D Cube building in Paris. The 4th dimension here is not about time, but the beauty of the abstract geometrical dimensions that exist in the mathematical world. I am always fascinated by the visualisation of 4th dimension or even n-th dimension in our 3D space.
