Setting up a hexagonal tiling grid

- [Instructor] In the last video…we covered some basic properties…of hexagonal tiling.…In this video, we'll put those principles to use…by making the starting points…of a parametric, hexagonal tiling algorithm…where eventually we can control…the number of rows and columns of hexagons.…In Rhino I've got the file hex-tiling.3dm open.…And in Grasshopper I've got the file…0020-hexagonal-tile.gh open.…So I'm going to focus on these five steps…in my algorithm,…and, in a later video, we'll get to the last two.…So, I'll slide these ones over…out of the way for now.…

Let's get started first on calculating…the horizontal and the vertical offsets.…So I'll also grab these bottom three.…Just put those kind of in the middle.…So, in order to calculate both of these offsets…we need some user-defined slider values.…I'm going to go ahead and make a slider…for a radius, and that will be a floating point value…probably between one.…We'll set to the default to 13,…and maybe we'll say 50 is the max.…

So I right-click and just title that as radius.…
