Loop Control:

The draw() loop is interrupted after a specific number of frames (frameMain). This approach prevents the program from running indefinitely, controlling the total generation time.

Continuous Generation: After completing a drawing cycle, the program is reset to generate a new composition. This means that art is generated continuously, creating a sequence of unique images.

Image Storage: At the end of each cycle, the resulting image is saved on the computer. Each image is unique since a random number is assigned as part of the file name, avoiding repetitions.

Infinite Art and Uniqueness: The continuous execution of the program ensures that art is generated infinitely. The assignment of a unique random number to each image file name ensures that no file name is repeated, contributing to the uniqueness of each composition.

Keep the p5.js window running indefinitely, generating unique posters continuously. At the end of each loop, save the image on the computer.

When the ‘N’ key is pressed, the applyNoiseEffect() function is triggered. This function adds a grainy noise effect to the entire canvas. Here’s a step-by-step explanation:

  1. Create an Off-screen Buffer:
    • A new off-screen buffer is created with the same dimensions as the main canvas (3500 x 5000 pixels).
  2. Set Background to Black:
    • The background of the off-screen buffer is set to black.
  3. Iterate Through Pixels:
    • The function loops through each pixel in the canvas.
  4. Add Noise to Brightness:
    • For each pixel, a random value between -10 and 10 is added to its brightness. This randomness creates a noisy effect.
  5. Set Pixel Colors in Buffer:
    • The modified brightness values are assigned as the red, green, and blue components of the pixel color in the off-screen buffer.
  6. Draw Buffer onto Main Canvas:
    • The buffer, now containing the noisy effect, is drawn onto the main canvas at the center.

In summary, pressing ‘N’ introduces a visual noise effect by randomly adjusting the brightness of each pixel in the canvas, creating a textured and dynamic appearance.

Noise in “HUMANITY” Art Project:

Role of Noise:

  • Unpredictability: Perlin noise introduces randomness to agent movements, ensuring each path is unique.
  • Visual Complexity: Noise creates intricate patterns, adding depth and complexity to the artwork.

Implementation:

  • Time-Dependent Noise: timeOffsetX and timeOffsetY evolve noise over time, contributing to dynamic lines.
  • Vector Field and Randomness: Noise guides vector field angles, while random components enhance unpredictability.
  • Gradient Stroke and Color: Noise interpolates colors, resulting in a harmonious and evolving color palette.

Data + API

In the provided code, there’s an example of using an API to fetch information about countries. Let me break down the relevant parts:

API Request:

  • The fetch function is used to make a network request to the given URL, which is an API endpoint that provides information about all countries.
  • The response from the API is initially in a raw format. The .json() method is called on the response to parse it as JSON.
  • The data is then processed in the .then block, where you can perform operations on the received data.
  • If there is any error during the request, it’s caught in the .catch block and an error message is logged.
fetch("https://restcountries.com/v2/all") 
.then((response) => response.json())
.then((data) => { // Process data here })
.catch((error) => console.error("Error fetching country data:", error));

Processing Data:

  • The data received from the API contains information about all countries. In this example, it’s assumed that data is an array of country objects.
  • The array allCountries is populated with all the country objects, and remainingCountries is initialized with the same data.
  • nAgents number of random countries are selected from remainingCountries without repetition, and these selected countries are pushed into the selectedCountries array.
  • Agents are then initialized using the Agent class with random positions and the selected countries.
.then((data) => {
// Store all countries in the allCountries array
allCountries = [...data];
remainingCountries = [...data]; // Initialize remainingCountries

// Select nAgents random countries without repetition
for (let i = 0; i < nAgents; i++) {
const randomIndex = Math.floor(Math.random() * remainingCountries.length);
const selectedCountry = remainingCountries.splice(randomIndex, 1)[0];
selectedCountries.push(selectedCountry);
}

// Log the selected countries
console.log("Selected Countries:", selectedCountries);

// Initialize agents after fetching country data
for (let i = 0; i < nAgents; i++) {
agents.push(new Agent(random(width), random(height), [selectedCountries[i]]));
}
longestLineAgent = agents[0];
})

Agent Class Initialization:

  • The Agent class is used to create instances (agents) that will be responsible for drawing lines on the canvas.
  • Each agent is initialized with a random position and an array containing one of the selected countries.
  • The Agent class constructor takes care of loading the flag image of the starting country and other initializations.
for (let i = 0; i < nAgents; i++) {
agents.push(new Agent(random(width), random(height), [selectedCountries[i]]));
}

In summary, the code demonstrates how to use an API to fetch country information, process that data, and use it to initialize drawing agents on the canvas. The fetched data is then used creatively in the drawing process based on the logic implemented in the Agent class.

The “Winner Determination”

Initialization:

  • The longestLineAgent variable is declared at the beginning to keep track of the agent with the longest drawn line. It is initially set to agents[0] (the first agent in the array).
let longestLineAgent;

Update During Drawing:

  • As the draw function is continuously called, the agents move across the canvas, leaving trails. The length of each agent’s drawn line is continuously updated.
this.drawnLineLength += dist(this.pOld.x, this.pOld.y, this.p.x, this.p.y);

Winner Determination:

  • After a certain number of frames (frameMain), the code checks for the agent with the longest drawn line. This is done by comparing the drawnLineLength property of each agent.
longestLineAgent = agents.reduce((a, b) =>
a.drawnLineLength > b.drawnLineLength ? a : b
);

Display Winner Information:

  • The winner’s information is then stored in the winnerInfo object, including the country name, area, capital, population, and latitude/longitude.
winnerInfo = { 
name: longestLineAgent.selectedCountry.name, 
area: longestLineAgent.selectedCountry.area, 
capital: longestLineAgent.selectedCountry.capital, 
population: longestLineAgent.selectedCountry.population, 
latlng: longestLineAgent.selectedCountry.latlng, };

Display Winner Information in the End:

  • The winner’s information can be displayed towards the end of the animation.
if (frameCount > frameMain - 2) { 
if (longestLineAgent) { 
longestLineAgent.displayWinnerInfo(); } }

Process in the provided code is based on the length of the lines drawn by the drawing agents (represented by instances of the “Agent” class). The agent with the longest drawn line is considered the “winner.” Here’s how it works:

In summary, the “Winner Determination” process involves monitoring the length of the lines drawn by each agent and identifying the agent with the longest line as the winner. The winner’s information is then stored and can be used for display or further processing.

Culture + Code

In terms of culture, the code integrates information about various countries, highlighting their diversity and uniqueness. The selection of countries and the use of their characteristics to influence the artwork reflect a celebration of global unity and collaboration. The visual representation of these countries, their flags, and associated information transforms cultural diversity into a form of artistic expression.

The intention behind the code seems to align with the idea that true power and beauty emerge not from individual nations but from the collective unity of diverse cultures. By bringing together elements from different parts of the world, the code transforms cultural richness into a captivating piece of digital art. This fusion of cultures in the code serves as a metaphor for the idea that collaboration and unity among nations can lead to the creation of something truly extraordinary and aesthetically pleasing, much like the visual output of the code itself.

The overarching theme of the project, “HUMANITY by Vadym Alyekseyenko,” suggests a focus on the shared human experience and the potential for collaboration and creativity to transcend borders. The integration of country-specific data in the artistic process conveys a message of interconnectedness and the beauty that emerges when diverse elements come together harmoniously.
