THE MAGNETIC DOT ENCYCLOPEDIA

Triangular Grid tutorial - tetrahedron, octahedron and icosahedron Like

by: Damian Follow


These are the three shapes possible with this technique

I'm interested to see video responses from anyone who makes this (and/or comments/likes/feedback/etc)
These shapes are hard to make and hard to understand and the video is really not very easy to follow, despite my best effort, but the shapes are really cool and I think its quite interesting to understand how the direction of the magnets is very different in otherwise identical seeming sections of the grid pattern. For every real hexagon in the pattern, there are three illusory hexagons, in the sense that their magnetic N-S directions are not pointing around the circumference of the hexagon. The are made up of the sides of two triangles and the points of two normally formed hexagons. See the diagrams below.


Tetrahedron


This diagram shows the general layout of triangles and hexagons. Also shown Is the way in which 3 out of 4 of the apparent hexagons in the grid are made up of the outside of the hexagons shown blue and the triangles. The magnetic field of those magnets does not point around the circumference of the hexagons


An example of the layout of one side of a small octahedron. The tetrahedrons shown have larger sides (more hexagons)

    thanks Waynehjr1 - I'm still waiting for the video to upload, which still has a couple more hours to go. If you were interested in making these, I think you could make them look amazing with your talent for colour (also check out some pics by sonyador6 on flickr, who makes (less dazzling) color patterns in this pattern, in big flat mandala style. )

    I will. I like experimenting with any new techniques..xD. I'll also check you out on flickr, as I am there also with same name as here...lol.

    As always I definitely appreciate the effort you put into this tutorial. You make the best "pillow" patterns!! I will be trying these out!
