Adding shapes without overlapping

jddschouten

Hello For my project I want to fill the field with these different patterns (will be more). They should get a random location on the screen but they shouldn't overlap each other. If anyone has some suggestions how I could do this that would be great. I do not a lot of experience with Processing.

Here is my code:

float[][] coordinatesHex1 = {{12.7,20.3},{12.7,14.4},{12.8,14.4},{14,12.2},{13.9,12.2},{17.2,10.2 },{17.3,10.3 },{19.7,10.3 },{21,8.2 },{19.7,6.1 },{17.3,6.1 },{16.1,8.2 },{16.1,8.3 },{12.8,10.2 },{12.8,10.1 },{10.3,10.1 },{10.3,10.2 },{7,8.3 },{7,8.2 },{5.8,6.1 },{3.3,6.1 },{2.1,8.2 },{3.3,10.3 },{5.8,10.3 },{5.8,10.2 },{9.1,12.2 },{9.1,12.2 },{9.1,12.3 },{5.8,14.2 },{5.8,14.2 },{3.3,14.2 },{2.1,16.3 },{3.3,18.4 },{5.8,18.4 },{7,16.3 },{7,16.2 },{10.3,14.3}, {10.3,14.4 },{10.4,14.4 },{10.4,20.3}};
float[][] coordinatesHex1_2 = {{12.7,20.3},{12.7,14.3 },{12.8,14.3 },{12.8,14.3 },{16.1,16.2 },{16.1,16.3 },{17.3,18.4},{19.8,18.4 },{21,16.3 },{19.8,14.1 },{17.3,14.1 },{17.3,14.2 },{14,12.3 },{14,12.2 },{12.8,10.1 },{10.3,10.1},{9.1,12.2},{10.3,14.3},{10.4,14.3}, {10.4,20.3}};  

void setup() {
  size(800,800);
  smooth();
  background(255);
}
void draw() {
  float x = random(width);
  float y = random(height);

  stroke(0);
  strokeWeight(0.1);
  noFill();
  pushMatrix();
  translate(x, y);
  rotate(radians(random(-45, 45)));
  beginShape(LINES);
  for (int i = 0; i < coordinatesHex1.length-1; i++) {
    for (int j = 0; j < coordinatesHex1.length-1; j++) {
      vertex(coordinatesHex1[i][0],coordinatesHex1[i][1]);
      vertex(coordinatesHex1[i+1][0],coordinatesHex1[i+1][1]);
    }
  }
  endShape(CLOSE);
  popMatrix();
  resetMatrix();

  stroke(0);
  strokeWeight(0.1);
  noFill();
  pushMatrix();
  translate(x, y);
  rotate(radians(random(-45, 45)));
  beginShape(LINES);
  for (int i = 0; i < coordinatesHex1_2.length-1; i++) {
    for (int j = 0; j < coordinatesHex1_2.length-1; j++) {

      vertex(coordinatesHex1_2[i][0],coordinatesHex1_2[i][1]);
      vertex(coordinatesHex1_2[i+1][0],coordinatesHex1_2[i+1][1]);
    }
  }
  endShape(CLOSE);
  popMatrix();
  resetMatrix();
}
