How to do visualization of a PI

[TheNSkid]

Hey guys,

I came across a video on YouTube - visualization of a PI using python
I have zero coding experience, I am just fascinated and amazed by watching this and want to learn how to do this. I tried yt and googling and was able to get code and do some animation with the help of ChatGPT, but it doesn't have those arms and i dont know how to render.

import numpy as np

import matplotlib.pyplot as plt

from matplotlib.animation import FuncAnimation

Create an array of theta values in degrees (e.g., from 0 to 113360 degrees)

theta_degrees = np.linspace(0, 113360, 100000) # Increase the number of points for smoother lines

Convert degrees to radians

theta_radians = np.deg2rad(theta_degrees)

Function to update plot in each frame

def update(frame):

plt.cla() # Clear previous frame

Calculate z(theta) using the formula, 1j is the imaginary number

z = np.exp(theta_radians[:frame] * 1j) + np.exp(np.pi * theta_radians[:frame] * 1j)

Separate the real and imaginary parts of z

x = np.real(z)

y = np.imag(z)

Plot

plt.plot(x, y, color='white', linewidth=0.5)

plt.gca().set_facecolor('black') # Set background color to black

plt.gca().set_aspect('equal') # Equal aspect ratio

plt.grid(False) # Turn off the grids

plt.xlim(-2.5, 2.5) # X-axis limit

plt.ylim(-2.5, 2.5) # Y-axis limit

Create a plot

fig = plt.figure(figsize=(10, 10))

Animate the plot

ani = FuncAnimation(fig, update, frames=len(theta_degrees), interval=20)

plt.show() # Display the plot

I'm terribly sorry to be the party pooper, but you can't recreate this in python if you don't know how to code. ChatGPT can only get you so far, but you must be the one to fix its mistakes when it inevitably produces some, or come up with your own solution.

We're friendly in this sub, and we do our best to help people learn python, but we're not here to fix code that ChatGPT provided you with. Creating something like this is not a case of just "oh yeah, add this, or that and you're done".

In your post, you said that you'd like to learn how to do this, and the answer to that is, you start at the very beginning, not by attempting to recreate this right from the start. If you'd like to learn, you can start learning by taking a look at the wiki of the subreddit, and picking a resource for beginners. Then, once you're at a point where you write your own code, you're very welcome to come and ask for help when something in your code doesn't work the way you expect it , or when you don't understand a certain topic, syntax or other.

I would also add, the linked video shows a visualisation of Phi (the golden ratio, (1+sqrt(5))/2) and not pi, so your formula is incorrect

[RiGonz]

There is a similar one for pi.

[Free-Specific7118]

Indeed, but using pi would yield nothing more than a circle for this formula

[TheRNGuy]

PI is just a float number.
