Hypercube Transcript: http://4d.shadowpuppet.net version: 3.2 2005.05.05 Ascii art in Lucida Console font: Regular 10pt 0D: 1. We begin with a zero dimensional point. 2. A point has no mass, and its size is undefined. 3. A point is one vertex, representing a position in space. . Interactive Mode: Click the mouse on the screen to relocate the zero dimensional point. ---------------------------------------- 1D: 1. Conecting 2 points in space, creates an edge. 2. with one dimension, a point has one set of independent directions, which I will arbitrarily call Up and Down. 3. We can now measure this space, and again arbitrarily call it Length. ._____________. Interactive Mode: Click and drag the point, forward and back, along the edge. This is a one dimensional plane. ---------------------------------------- 2D: 1. In 2 dimensional space, an edge may move to make a square. 2. We can now measure this space in a second way. This time WIDTH. 3. Now we have 2 sets of independent directions, which we can call UP/DOWN & LEFT/RIGHT. 4. These 2 sets can be combined to form an infinite set of dependant directions. ._____________. | | | | | | | | | | | | |_____________| Interactive Mode: Use the arrow keys to move up, down, right, and left. This is a 2-dimensional world, the same as a nintendo video game. ---------------------------------------- 3D: 1. In 3D, a Square may expand FORWARD and BACK to make a cube. 2. Now we have DEPTH and 3 sets of independent directions. 7-----------4 /| /| / | / | / | / | / | / | 3-----------0 | | | | | | | | | | | | | | 6------|----5 | / | / | / | / | / | / |/ |/ 2-----------1 Interactive Mode: You may use the mouse to click the buttons on the screen to rotate or resize the cube. Alternatively, you may press the following buttons: l = rotates left r = rotates right u = rotates up d = rotates down z = rotates forward x = rotates backward + = zoom in - = zoom out You may also hold multiple keys or hold a key while clicking a button to move in a combination of directions. ---------------------------------------- 4D: 1. In 4d, we have a new set of indepedent directions, which I will call ANA and KATA 2. Duplicating a cube in this way gives us a hypercube. 3. I will call this measurement Spassitude. 4. Just as a Cube has a volume of one, a hypercube has hypervolume of one. And as a CUBE contains 6 sqaures, a Hypercube contains 8 CUBES. 5. Just as with a cube, each angle is 90 degrees, which is an imperfect illusion in this 2d sketch. 15----------------12 /| /| / | / | / | / | / | / | / | / | / | / | 11-----------------8 | | | | | 7------|-----------4 | | /| | | /| | | / | | | / | | | / | | 14/--|------|-----13 / | | / / | | / / | | / / | | / / | | / / | | / 3------------------0 | | / | | | / | | | / | | |/ | | |/ | | 10---|-------------9 | | | | | 6-----------|------5 | / | / | / | / | / | / | / | / | / | / |/ |/ 2------------------1 Interactive Mode: You may use the mouse to click the buttons on the screen to rotate or resize the cube.

Click on the Model buttons to change the starting form of the Hypercube. --------------------------------- the only way to truly see four dimensional space is to overcome the mental conditioning that space only has 3 dimensions. 5.1 over 500 years ago, we decided the world was round. We see and feel a sphere, but we only see and feel 3d of space. Someday we may interact with more spacial layers and see that from a certain perspective, the world was flat all along.
