#harmonic

Have you ever thought about making a damped pendulum in Grasshopper? I have no idea why, but I did. I just decided to transfer a Python snippet I found online into a Grasshopper definition. Here, the Initial Angle (Radians) Number slider sets the initial angle to any value from 0 to Pi. The letter G represents the acceleration due to gravity (approximately 9.81 m/s2). This is the primary force pulling the pendulum downward. As you know, pendulums wouldn’t swing without…

While trying to program the curves produced by Spirograph toys in Grasshopper, I took a slightly different path. The topic eventually led to a broader heading: harmonic motion, and from there, to the Fourier Series we looked at previously. This simple Python code models Fourier Synthesis, driven by circles of different radii in a very straightforward way. The Python component sets up a loop that calculates the effect of each circle to the x and y values, individually. In this…
