Those are the 3D dimensions of the tesseract that will be modeled in Rhino and eventually 3D printed. Each result can then be projected down to 3 dimensions. Then multiply each by the appropriate 4D rotation matrix and translate in the positive \(v\) direction away from the origin. These are fundamental to my thinking this through and understanding what I am building. I can simplify my workload by considering this in my design.Įqually important are the sketches of the equations behind this project. Also, there is symmetry in that rotations between 45 and 90 degrees are mirror images of rotations between 0 and 45 degrees. It is easier to think about them after doing the math, but even then, it is not easy drawing a 4D object on a 2D piece of paper.Ī rotating tesseract will repeat itself after a 90 degree rotation. My drawings of a tesseract are terrible because they are almost impossible to visualize. ![]() Designing a Tesseractįirst, I started with some sketches. This project was inspired in part by the book Visualizing Mathematics with 3D Printing. These 3D printed tesseracts can be assembled in a stop motion animation to show what the tesseract looks like as it rotates around 4D space. Using math and 3D printing, I can create multiple versions of a rotating tesseract. Similarly, a rotating tesseract can help us understand what they are like. A 2D being cannot understand, visualize, or fully experience a cube, but as a cube rotates around, they can gain a better understanding of what the structure is like. Tesseracts can interact with a 3D world in a way that is similar to a cube interacting with a 2D world. They are theoretical structures that can be understood mathematically. Tesseracts are challenging for 3D beings to visualize and understand. It is analogous to a cube in our 3D world. A tesseract, or hypercube, is a 4 dimensional cube. To explore this, I will analyze and study a tesseract. Choose cross-eyed viewing or parallel viewing, then move your eyes to merge two images.I am interested in using 3D printing to model and visualize mathematics. This switch enables stereopsis of the polytopes. "Flat, Cross, Parallel" Switch (in index pages) ![]() You can also change the marking color in the same way with "Hue". The angle between the color light sources varies every time you tap "Angle". Tapping each button saves, shares or sends a content with one of the file extensions. You can capture still and moving images on the screen. "English" button, which is revealed with a non-English article, takes you to the equivalent in English. This button provides the links to Wikipedia articles describing the polytopes. If you switch this setting to "Mark", one of the cells or faces of each polytope will be marked in your selected color. When this setting is switched to "Sync", the light sources revolve in synchronization with the rotation of polytopes. You can choose which to use to illuminate the polytopes. This button toggles between colorful and white light. Swiping left and right switches between 4D and 3D. Swipe the screen of your device up or down with three fingers to see another polytope of the same dimensions. These gestures are only available for the 4D polytopes. Pinching in and out with two fingers starts rotation between the hidden fourth spatial axis and the other axes. Buttons on the screen offer some effect options that can be applied to the polytopes, which helps you understand four-dimensional space.įlick the polytope currently displayed with one finger and it will rotate in our usual three-dimensional space. Simple touch gestures let you intuitively manipulate those geometric figures. Have you ever wanted to see and touch four-dimensional objects? 4D Polytopes is a real-time visualization app that renders the four-dimensional convex regular polytopes such as the tesseract as well as the three-dimensional ones known as the Platonic solids. ![]()
