1. Introduction

1.1 Project Overview

This documentation explores a creative generative art project developed using p5.js. The project involves generating unique and visually appealing artwork based on a given input image. The art is created by employing a combination of random walkers that traverse the canvas, averaging pixel colors, and providing a real-time drawing effect.

1.2 Objective

The primary objective of this project is to harness the potential of generative algorithms to transform an input image into a distinctive and visually intriguing artwork. By utilizing random walkers and pixel color averaging, this project aims to offer a creative and dynamic approach to image interpretation.

1.3 Creative Approach

The project’s creativity lies in its unique amalgamation of pixel color manipulation and random walker behavior. Instead of a straightforward one-to-one mapping of image pixels, the art is generated by iteratively averaging the colors of neighboring pixels. Additionally, the art’s dynamism is achieved through the use of random walkers that contribute to the image in real-time, giving it a captivating and evolving appearance.

2. Getting Started

2.1 Setting Up p5.js

To begin, ensure you have p5.js set up in your development environment. You can download the p5.js library from the official website (https://p5js.org/). Follow the installation instructions provided on the website.

2.2 Importing the Image

Start by importing the image you wish to transform creatively into your p5.js sketch. You can use the loadImage() function to load the image and display it on the canvas.

2.3 Initializing the Random Walkers

Create random walkers that will move across the canvas. Each walker’s behavior and appearance can be customized according to your creative vision. Initialize these walkers with random starting positions and directions.

3. The Generative Process

3.1 Pixel Color Averaging

The core of this project’s creativity lies in pixel color averaging. Instead of mapping image pixel colors one-to-one, calculate the average color of a pixel’s neighborhood (e.g., a 3×3 or 5×5 grid of surrounding pixels). This technique introduces a smoothing effect and adds uniqueness to the generated artwork.

3.2 Random Walkers

The random walkers contribute to the creative process by traversing the canvas and drawing pixel colors. Customize the walker’s step size, direction changes, and color selection. The random nature of the walkers ensures that each run generates a distinct artwork.

3.3 Real-time Drawing Effect

The magic happens when the walkers contribute to the drawing of the image in real-time. As walkers move across the canvas, they apply the averaged colors to the corresponding pixel locations. This real-time interaction creates an intriguing and dynamic visual effect as if the image is being drawn before your eyes.

4. Enhancing Creativity

4.1 Adjusting Walker Behavior

Experiment with different walker behaviors to achieve a variety of artistic effects. You can control parameters such as step size, direction changes, and the duration of each walker’s journey.

4.2 Modifying Averaging Techniques

Project Description

Overview

This project is an interactive visual representation of simple harmonic motion, inspired by the Gaussian distribution curve, using P5.js. It creates a captivating display of 3D hexagons that rotate in the XY-plane while also oscillating in the Z-axis. Each hexagon has a progressively smaller radius than the one before it and undergoes harmonic motion both in terms of its position and color, resembling the shape of a Gaussian distribution curve.

Motivation

The motivation behind this project stems from the fascination with the Gaussian distribution, also known as the normal distribution or bell curve. The Gaussian distribution is a fundamental concept in statistics and probability theory, frequently encountered in various scientific and real-world contexts. It describes the probability distribution of a continuous random variable and is characterized by its symmetric, bell-shaped curve.

This project seeks to bridge the gap between the abstract beauty of mathematical concepts and their visual representation in art and technology. By drawing inspiration from the Gaussian distribution, it aims to provide an engaging and aesthetically pleasing way to explore the principles of simple harmonic motion. The visual resemblance to the Gaussian curve adds a layer of intrigue and connection to a concept that might otherwise be considered purely mathematical.

Project Appearance

The project presents a visually stunning 3D animation that draws inspiration from the Gaussian distribution curve. Here’s what you can expect:

• Hexagons: There are 50 hexagons in total, each positioned in 3D space. The hexagons are arranged in a spiral pattern, with each hexagon having a smaller radius than the previous one, creating a visually appealing tapering effect.
• Rotation: Each hexagon continuously rotates in the XY-plane. The rotation is driven by trigonometric functions, with the cos() function controlling the x-coordinate and the sin() function controlling the y-coordinate. This results in a circular movement for each hexagon, but with distinct positions and paces for each one.
• Harmonic Motion: The project utilizes the sin() function on the current time value to manipulate the z-coordinate of each hexagon. This creates a mesmerizing effect where each hexagon appears to rise and fall in a harmonic motion pattern along the Z-axis, resembling the peaks and troughs of a Gaussian distribution curve.
• Color Transformation: The project goes one step further by applying harmonic motion to the color of each hexagon. Custom RGB colors are generated by applying sin() and cos() functions to the time value. As a result, the colors of the hexagons smoothly transition, creating a beautiful visual representation that closely resembles the colors associated with a Gaussian distribution curve.

Conclusion

In summary, this P5.js project is a captivating visualization of simple harmonic motion in 3D space, inspired by the shape of a Gaussian distribution curve. It features a mesmerizing spiral of rotating hexagons, with each hexagon undergoing harmonic motion along the Z-axis and experiencing a harmonious color transformation that evokes the colors of a Gaussian distribution. The project beautifully bridges the worlds of mathematics, art, and coding, offering a visually striking and educational representation of harmonic motion and probability distributions.

Concept

The “2D Simulation of 3D Object with Attractors and Movers” is a P5.js project that explores the behavior of a simulated 3D object within a 2D plane. The core concept involves creating an illusion of three-dimensionality through the interaction of attractors and movers in a confined space. Here’s how the concept breaks down:

• Attractors: The project begins by introducing invisible attractors, positioned at the four vertices of a square. These attractors act as gravitational centers, exerting forces on nearby objects.
• Movers: Movers are dynamic entities with mass and radius. They are introduced into the scene and interact with the attractors and each other. The movers are attracted to the invisible attractors, simulating gravitational forces. Additionally, movers attract each other, contributing to the complex dynamics of the simulation.
• Initial Direction: To establish an organized start, the movers’ initial velocity vectors are set to be perpendicular to their position vectors. This arrangement ensures that all movers begin moving in the same direction.
• Visual Illusion: The project employs lines connecting each pair of movers, creating a visual effect resembling a rotating 3D object. This illusion is achieved in a 2D plane, as P5.js primarily supports 2D graphics.
• Boundary Constraints: To introduce chaos and turbulence into the simulation, movers are constrained by the boundaries of the canvas. When a mover reaches the boundary, it reverses its velocity, contributing to the overall dynamics and eventual chaos of the system.

Inspiration

The inspiration for this project likely draws from the desire to replicate the complex and chaotic movements of objects in a 3D space using the capabilities of P5.js, a 2D graphics library. The concept of simulating gravity and interactions between objects is a common theme in physics simulations and computational art.

Raindrop Simulation Documentation

Introduction

The Raindrop Simulation is a p5.js project that simulates the behavior of raindrops falling from the sky. This project is an example of using rules and physics to replicate a real-world natural phenomenon. In this documentation, we will provide a detailed description of what the simulation does, how it works, and how users can interact with it.

Project Description

What It Does

The Raindrop Simulation replicates the following characteristics of raindrops:

1. Gravity: Raindrops are affected by gravity, causing them to accelerate as they fall.
2. Wind: A simulated wind force pushes raindrops horizontally, creating a drifting effect.
3. Variable Gravity: Users can interact with the simulation by temporarily increasing the gravity force when the “Up Arrow” key is pressed. This causes raindrops to fall faster and create a denser rainfall.
4. Splash Effect: When a raindrop hits the ground (the bottom of the canvas), it creates a splash effect.
5. Raindrop Removal: Users can decrease the gravity force by pressing the “Down Arrow” key, making raindrops fall more slowly. This allows for the removal of raindrops from the simulation.

User Interaction

The user can interact with the Raindrop Simulation using keyboard inputs:

• Up Arrow Key: When pressed, it increases the gravity temporarily, causing raindrops to fall faster and more intensely.
• Down Arrow Key: When pressed, it decreases the gravity, making raindrops fall more slowly. This also allows for the removal of raindrops from the simulation.

Introduction

The Walker is an interactive p5.js project that creates a constantly morphing creature that moves in random directions on a canvas. This project utilizes JavaScript and the p5.js library to generate a visually intriguing and ever-changing artwork. In this documentation, we will provide a detailed description of what the Walker does, what the user can expect, and any interactive elements involved.

Project Description

What It Does

The Walker is an abstract creature that appears to be walking across the canvas. It constantly changes its shape, giving it an amorphous and unpredictable appearance. The key features of the Walker project are as follows:

1. Random Movement: The Walker moves in random directions, making it appear as if it is wandering aimlessly across the canvas.
2. Mouse Interaction: There is a 50% chance that the Walker will move towards the mouse cursor’s position. When this happens, it appears as though the creature is attracted to the mouse.
3. Shape Morphing: The creature’s shape is continually changing. It starts with a predefined shape made up of random vertices, and these vertices are updated randomly, causing the creature to morph over time.

User Interaction

The user’s interaction with the Walker project is minimal but plays a crucial role in shaping the creature’s movement. Here’s what the user can do:

• Mouse Movement: When the user moves their mouse cursor within the canvas, the Walker may respond by moving towards the mouse cursor with a 50% probability. This interaction creates a dynamic relationship between the user’s cursor and the creature’s movement.

Implementation

Walker Class

The Walker is implemented as a JavaScript class with the following methods:

• Constructor: The constructor sets up the initial position of the Walker at the center of the canvas and initializes the creature’s shape with a random set of vertices.
• step(): This method controls the Walker’s movement. It calculates a random number to determine whether the Walker should move towards the mouse cursor or in a random direction. If the decision is to move towards the mouse, it adjusts the position of the Walker accordingly. Otherwise, it moves the Walker randomly. The Walker’s position is constrained within the canvas boundaries.
• display(): The display() method is responsible for rendering the Walker on the canvas. It draws the creature as a shape with constantly morphing vertices.
• updateBounds(): This method randomly updates the positions of the creature’s vertices, causing it to morph and change shape.

Setup and Draw Functions
