1 Line: Blowout

 

 

Two shots of a starting generation.

This is a simple test piece involving the reaction of a single line to the mouse. The line in randomly generated, and the points used to construct the curve will move away from the mouse to warp the shape they create.

code:

//Blowout. When you're swirly and you're curly, then you're kitsch

int[] points;
int[] mpoints;

//generates the points used to make the base curve, as well as define
//the static edge cases for the rendered lines
void setup(){
  size(600,600);
  points = new int[24];
  points[0] = 0;
  points[1] = 0;
  points[22] = width;
  points[23] = height;
  for(int i = 0; i < 10;i++){
    points[2*(i+1)] = int(width * noise((2*i)/1.0));
    points[(2*(i+1)+1)] = int(height * noise((2*i + 20)/1.0));
  }
  for(int i = 0;i<12;i++){
    println("point "+i+": "+points[2*i]+", "+points[(2*i)+1]);
  }
  mpoints = new int[24];  
  mpoints[0] = 0;
  mpoints[1] = 0;
  mpoints[22] = width;
  mpoints[23] = height;
}

//adjusts the rendered point based on the position of the mouse.
int[] adjust( int x, int y, int px, int py){
  int[] result = new int[2];
  float dist = sqrt(sq(px-x) + sq(py-y))/60.0;
  if(dist == 0.0){ dist = 0.1;} 
  result[0] = int(px + (px - x)/dist);
  result[1] = int(py + (py - y)/dist);
  return result;
}

int[] pair;

//creates an updated version of each point based on the original
//generation and the position of the mouse, then draws the line
void draw(){
  background(255);
  int x = mouseX;
  int y = mouseY;
  for(int i = 0; i < 10 ; i++){
    pair = adjust(x, y, points[2*(i+1)], points[(2*(i+1))+1]);
    mpoints[2*(i+1)] = pair[0];
    mpoints[(2*(i+1))+1] = pair[1];
  }
  strokeWeight(3);
  noFill();
  stroke(0,0,0);
  curve(mpoints[0],mpoints[1], mpoints[0],mpoints[1],
        mpoints[2],mpoints[3], mpoints[4],mpoints[5]);
  for(int i = 0;i<9;i++){
    curve(mpoints[2*i],mpoints[2*i+1], mpoints[2*i+2],mpoints[2*i+3],
          mpoints[2*i+4],mpoints[2*i+5],mpoints[2*i+6],mpoints[2*i+7]); 
  }
  curve(mpoints[18],mpoints[19], mpoints[20],mpoints[21], 
        mpoints[22],mpoints[23], mpoints[22],mpoints[23]);
}
