This is a small exercise of Grasshopper drawing various archimedean spirals. It is just a polar point construct, mapped onto a range of angles and number of points. Constant a determines how fast the spiral will turn, whereas constant n is the 1/n power of the angle variable that gives unique names to the spirals. According to Woldfram Mathworld (here) constant n = -2 is named lituus, while n = -1 gives a hyperbolic spiral, n = 1 is a regular archimedes spiral and finally n = 2 will give […]
