Drawing Rough Lines

About Project:

I found this sketch (PT_97) in last year's project folder, and I appreciate it more now. So, I've decided to share it here. This sketch uses Processing code to analyze and create lines to connect points. While creating the lines, I experimented with various methods. Each method, when combined, results in different textures.

// Function to draw a rough line between points with added noise and displacement.
void drawRoughLine(PVector start, PVector end, float displacement, int depth) {
  // Determine when to stop recursion based on segment length and depth.
  float threshold = max(2, amplitude + noiseStep * 10);

  // Base case: draw the line if the segment is short enough or recursion depth is too great.
  if  (depth > 20 || dist(start.x, start.y, end.x, end.y) < threshold) {
    float variableStroke = map(dist(start.x, start.y, end.x, end.y), 0, width, 1, 9);
    variableStroke += random(-0.5, 0.5);  // Add randomness to line thickness.
    strokeWeight(variableStroke * (2 * mouseYFactor));  // Adjust line thickness.

    // Draw the line segment.
    line(start.x, start.y, end.x, end.y);
    return;
  }

  // Calculate the midpoint of the line segment.
  PVector midpoint = new PVector((start.x + end.x) / 2, (start.y + end.y) / 2);
  // Adjust the midpoint using random displacement and noise (a form of randomness).
  float noiseValue = noise(midpoint.x * noiseScale, midpoint.y * noiseScale, t);
  midpoint.y += (random(-displacement, displacement) + (noiseValue - 0.5) * amplitude) * noiseStep;

  // Recursively draw the two halves of the line segment.
  drawRoughLine(start, midpoint, displacement / 2, depth + 1);
  drawRoughLine(midpoint, end, displacement / 2, depth + 1);
}
