Generative art involves the creation of art through autonomous systems and randomness, utilizing algorithmic processes to produce abstract patterns. The document discusses methods for generating random-like values using techniques like Perlin noise and iterative variance, as well as concepts such as flocking behavior and fractals. It encourages experimentation through interaction and various outputs, illustrating the potential of combining different artistic effects.

1. Introduction to Generative Art

3. What is Generative Art?
• Art creation involves autonomous system and certain
kind of randomness.
• Algorithmic Art
• Abstract pattern

4. Content will be covered today.
• Some functions generating random-like value.
• Some abstract patterns.
• Some works.

5. Why we need random-like value generator in generative
art?
Deterministic Random
parameter

6. Functions generating random-like value
• random
• perlin noise
• hybrid

7. Random example - line fluctuation
iterative variance

8. Perlin Noise

9. Line fluctuation with 1D Perlin noise

10. Make your own noise function
• 0.3 * random(1) + 0.7 * noise(1)
• pow(sin(val), random(3))
• …

11. Rotational Drawing
• (x-a)^2 + (y-b)^2 = r^2
•
(a,b)
x = a + r*sin(t)
y = b + r*cos(t)

17. Flocking
agents’ local behaviors
acting dependently
emergent behavior

18. Flocking - Boids
Separation: steer to avoid
crowding local flockmates
Alignment: steer towards the
average heading of local
flockmates
Cohesion: steer to move
toward the average position
of local flockmates

20. Fractal
a rough or fragmented
geometric shape that can
be split into parts, each of
which is (at least
approximately) a reduced-
size copy of the whole.
Benoit Mandelbrot, 1975

21. Fractal
In mathematics or
computer science, the
concept can refer to
Recursion

22. Fractal - The Mandelbrot Set
the complex numbers belong to this set as long as
the iteration remains bounded even if n approaches infinity
