Lernen Interactivity in Creative Coding | Creative Coding and Generative Art

Interactivity is a core concept in creative coding, allowing you to make your generative art respond to user actions or changes in parameters. This can be as simple as adjusting a slider to control the number of shapes, clicking a button to switch colors, or updating a variable to see a new version of your design. Interactivity brings your creations to life and invites experimentation, making the creative process more engaging and dynamic.

import matplotlib.pyplot as plt
import numpy as np

# Simulate user input by changing the 'num_circles' variable
num_circles = 10  # Try changing this value to 5, 15, or 20

theta = np.linspace(0, 2 * np.pi, 100)
x = np.cos(theta)
y = np.sin(theta)

plt.figure(figsize=(6, 6))
for i in range(num_circles):
    angle = 2 * np.pi * i / num_circles
    plt.plot(x + np.cos(angle), y + np.sin(angle))

plt.axis('equal')
plt.axis('off')
plt.title(f"Pattern with {num_circles} Circles")
plt.show()

By changing the value of a variable, such as the number of circles in the pattern above, you can simulate interactivity even without direct user input. This approach lets you explore how different parameters influence the final artwork. Each adjustment can lead to unexpected and interesting results, encouraging you to experiment with new ideas and discover creative possibilities you might not have considered before.

import matplotlib.pyplot as plt
import numpy as np

circle_counts = [5, 10, 15, 20]

fig, axes = plt.subplots(1, len(circle_counts), figsize=(4 * len(circle_counts), 4))

theta = np.linspace(0, 2 * np.pi, 100)
x = np.cos(theta)
y = np.sin(theta)

for ax, num_circles in zip(axes, circle_counts):
    for i in range(num_circles):
        angle = 2 * np.pi * i / num_circles
        ax.plot(x + np.cos(angle), y + np.sin(angle))
    ax.set_title(f"{num_circles} Circles")
    ax.axis('equal')
    ax.axis('off')

plt.tight_layout()
plt.show()
