Snow Globe

I felt inspired by some visual artists that used simple animations to create interesting effects in otherwise still art pieces. It’s sort of like the idea of a snow globe, changing around a still scenery. I decided to make an art piece that essentially replicated this.

I created a class that loops 100 times to create snow falling at different speeds down the screen, with an umbrella girl I drew from another drawing program I made. The user’s cursor is a snowflake. It’s like a simple interactive desktop image. I’m hoping to add to this by having snowflakes fall out of the cursor as it moves across the screen.

PImage Umbrella;

class Snow {
  float ySpeed;
  float diam;
  float xsky;
  float yPos;
  float opacity;
  float snowflake;

  Snow() {
    ySpeed = 0;
    diam = 0;
    xsky = 0;
    yPos = 0;
  }
  
  void drawing(){
    fill(35,1);
    strokeJoin(BEVEL);
    rect(600,330,100,200);
    fill(35,2);
    rect(600+10,330+10,100-20,200-20);
    fill(35,3);
    rect(600+20,330+20,100-40,200-40);
    fill(190,180);
  }
  void snowball() {
    fill(210, opacity);
    xsky = random(1, width);
    ellipse(xsky, yPos, diam, diam);
  }
  void falling() {
    ySpeed = random(-1, 12);
    yPos += ySpeed;
    if (yPos >= height) {
      yPos = 0;
    }
  }

  void snowsize() {
    diam = random(1, 25);
  }
  void opacity(){
    opacity = map(yPos,0, height*0.87,210,0);
}
  void cursory(){
    fill(225);
    pushMatrix();
    stroke(225,opacity);
    snowflake = 30;
    line(mouseX,mouseY,mouseX+snowflake,mouseY-snowflake);
    line(mouseX,mouseY-snowflake,mouseX+snowflake,mouseY);
    line(mouseX+snowflake/2,mouseY-snowflake,mouseX+snowflake/2,mouseY);
    line(mouseX,mouseY-snowflake/2,mouseX+snowflake,mouseY-snowflake/2);
    popMatrix();
    
    
    if(mousePressed == true){
      line(pmouseX,pmouseY,pmouseX+snowflake*2,pmouseY-snowflake*2);
      line(pmouseX,pmouseY-snowflake*2,pmouseX+snowflake*2,pmouseY);
      line(pmouseX+snowflake*2/2,pmouseY-snowflake*2,pmouseX+snowflake*2/2,pmouseY);
      line(mouseX,pmouseY-snowflake*2/2,pmouseX+snowflake*2,pmouseY-snowflake*2/2);
    }
    noStroke();
}
}


Snow[] unicorn;

void setup() {
  size(800, 600);
  background(35);
  noStroke();
  fill(250);
  Umbrella = loadImage("Umbrella.png");
  unicorn = new Snow[100];
  for(int q = 0;q<unicorn.length; q++){
    unicorn[q] = new Snow();
    
  }
    
}

void draw() {  
 image(Umbrella,600,330);
 noCursor();
 for(int q = 0;q<unicorn.length; q++){
    unicorn[q].snowball();
    unicorn[q].snowsize();
    unicorn[q].falling();
    unicorn[q].opacity();
    unicorn[q].cursory();
    //unicorn[q].drawing();
 }
    
  fill(35,10);
  rect(0,0,width,height);
