![]() What are 4D shapes? To understand this concept, let's first discuss the process of "projecting" a higher-dimensional object into the dimension below. In this blog post, we'll delve into the fascinating world of 4D shapes and introduce you to the regular convex 4-polytopes: the 5-cell, 8-cell, 16-cell, 24-cell, 120-cell, and 600-cell. Polytopes are geometric figures with flat faces in any dimension, and they include polygons, polyhedra, and their higher-dimensional counterparts. The world of geometry takes on a new dimension when we venture beyond the 3D shapes we're accustomed to and explore 4D shapes, or polytopes. "Four-dimensional space is not just an abstract concept, but rather an actual reality that is the natural extension of the three dimensions we are familiar with." - Ludwig Schläfli Hold down the right button to rotate the objects to check and examine the final product. ![]() Double-Click the word Perspective to maximize the Upper Right Quadrant perspective window. Right Click on the Shade tool to shade all viewports. Then Edit > Layers > Change Object Layer. Hold the Control key then click the A button to Select All. Select Copy, then copy the now-selected box in the Lower Left Quadrant to the right side of the model. Hold down the right button to rotate the objects to this approximate angle. In the Upper Right Quadrant perspective window. Click Copy, then copy these two boxes from the left to the right corners. ![]() In the Lower Left Quadrant, hold the Shift key, then click one of the lower, rotated skinny boxes to select a second object. In Lower Right Quadrant, Copy the skinny box to each of the other three corners. Right Click on Zoom Extents to zoom into model in each quadrant. ![]() Repeat this action in the Lower Right Quadrant. Rotate the tall, skinny box so that its bottom end intersects the top left corner of the lower right cube group. Left Click on the top left corner of the tall, skinny box. Select, then use Rotate tool to rotate the tall, skinny box in Lower Left Quadrant. Move the box so that its top left corner is in the top left corner of the cube group. Select, then use Move tool to move the tall, skinny box in Lower Left Quadrant. Select, then use Move tool to move the tall, skinny box in Lower Right Quadrant. On the bottom navigation bar click Snap and Ortho to turn them off.Ģ3. Should we wish to transcend the limitations of these measly 3 dimensions we must consider that which we have not previously experienced, back on the sheet-of-paper Universe.Ģ2. Were we stick figures living out our lives, strolling around on a sheet-of-paper Universe, it would be maddeningly confusing for someone to elucidate the "3rd dimension" to us when our entire culture has been defined by "up" & "down", "left" & "right". The 4th dimension upon which this instructable instructs is the spatial 4th dimension.ĭana Carvey as "the Church Lady" used to ask something like, "isn't that spatial?" Indeed it is. Einstein showed we live in 3 spatial dimensions with a 4th dimension of time. 3d modeling software (or download my design for free).or some excellent, Free 3d-modeling software at: If you want to try some 3d-modeling software for free, either get Rhino's evaluation copy at: ![]() If you wish to 3d-model your own 4d hypercube, I can offer instructions for Rhino. If you do not wish to create your own model in 3d-modeling software, you can take the easy way out and just download my model for free at: It is the second of two 3d models of 4d objects I'm uploading. It can also be described as a 3d shadow of a 4d model. This instructable explains how to produce a 3d model of a 4d cube. ![]()
