I do a lot of design work for 3D printing (see also: the MakerBot category on this blog). For some reason, I keep finding myself repeatedly doing a lot of math related to hexagons and the triangles that compose them. The first few times, I did the trigonometry by hand. Over time, I offloaded that to Google searches, but the results varied in consistency (across the weeks and whichever search terms I thought to use at the time) and quality (across the sites themselves).
I figured it was time to just make a high quality cheat-sheet for myself that I can refer back to at any point. Because I have no reason to keep it secret, and because it’ll be easier for me to find, I’m posting it here.
And to tie this back to yesterday’s post, this may also be of use with my experiments in Processing.
The “one, two, root three” mnemonic from high school has served me well for this case.
