Oppiskele Introduction to Generative Art | Creative Coding and Generative Art

Generative art is a form of art that is created with the help of autonomous systems, such as algorithms, computers, or mathematical processes. Unlike traditional art, where every detail is controlled by the artist, generative art relies on a set of rules or instructions that produce unpredictable or evolving results. This approach has deep roots, dating back to early computer artists in the 1960s who used plotters and simple code to create visual patterns. Today, generative art is highly relevant for creators and makers because it enables the creation of complex, intricate designs that would be difficult or impossible to produce by hand. Python, with its accessible syntax and powerful libraries, is an ideal tool for experimenting with generative art, allowing you to bring algorithmic creativity into your projects.

# Generate a simple repeating pattern using a loop
pattern = ""
for i in range(20):
    if i % 2 == 0:
        pattern += "*"
    else:
        pattern += "-"
print(pattern)

This code creates a visual pattern by looping 20 times and alternating between two symbols: an asterisk (*) and a dash (-). The if statement checks if the current index is even or odd, and adds the corresponding symbol to the pattern string. When you print the result, you see a sequence like *-*-*-*-*-*-*-*-*-*-, which forms a simple, repeating design. By changing parameters such as the number of repetitions or the symbols used, you can quickly explore different pattern variations and discover new visual effects.

import random

# Generate a random sequence of shapes for a unique design
shapes = ["○", "■", "▲", "◆"]
pattern = ""
for i in range(20):
    pattern += random.choice(shapes)
print(pattern)
