I've currently moved over to blogging at http://mathcraft.wonderhowto.com/

Here I will be posting about 4 times per week and will have a project every week with more in depth information and a how to component and templates. There will also be a user forum for people to submit pictures and ideas.

Thanks! I hope to see you there!

Simple Graphs

In graph theory a graph is a collection of nodes where connections between the two are shown by lines. This can easily be applied to polygons in order to draw non convex figures. You start off with a regular convex polygon and then to draw the regular star polygons you connect each vertex to another by skipping a certain number of nodes.

If you connect up each node to every other node you get what is called a simple graph which is actually the collection of every regular star polygon drawn on top of each other. Here is that graph for a 16-gon. I then filed in the resulting tiling so that no tile is ever touching another filled in tile along an edge. In the first one I then shaded all of those tiles in ROYGBIV color order. In the next two I took the original image and shaded in what ever was left white in ROYGBIV and VIBGYOR color order.
