Homework 1

Our first Homework was to create a slideshow of previously taken pictures. My topic was branches and this is my code:

PImage[] images = new PImage[9];

void setup() {
  size(300, 300);
  frameRate(5);
  for (int i = 0 ; i < images.length; i++)
  { 
    images [i] = loadImage("b" + nf(i+1, 2) + ".JPG");
  }
} 
void draw()
{
  int counter = frameCount % 9;
  image(images[counter], 0, 0, 300, 300);
}

which resulted in this:

Homework 2

In this homework we were supposed to do a collage. Mine was in the style of david hockney.

PImage[] images = new PImage[25];      // Array für Bildvariablen erstellt
PImage[] parts = new PImage[25];      //  Array für die Teile der Bilder erstellt
int x;
int y;

void setup() {
  size(500, 500);
  for (int i = 0 ; i < images.length; i++)
  { 
    images [i] = loadImage("b" + (i+1) + ".JPG");
  }
  for (int o=0 ; o < parts.length; o++)
 {
  images [o].resize(width,height); 
  image(images [o], 0, 0, 500, 500);
  x = (o % 5) * 100;
  y = (o / 5) * 100;
  parts[o] = get(x,y,100,100);            //Aus jedem Bild wird nur der Teil entnommen der benötigt wird
 }
  
}
void draw() {
  background(0);
  for (int i = 0; i < parts.length; i++){
    int x = (i % 5) * 100;
    int y = (i / 5) * 100;

  image(parts[i], x, y, 100, 100);        //Zusammensetzung aller Teile aus den verschiedenen Bildern zu einem Bild
  }
  for( int p = 0; p < 4;p++){
  rect((p*100)+98, 0, 4, 500);
  rect(0, (p*100)+98 , 500, 4);
  noStroke();
  }
  saveFrame("hockney.JPG");
}

the result:

Homework 3

PImage[] images = new PImage[19];
PImage alpha;

int w=100;
int h;

void setup() {
  size(400, 500);
  frameRate(10);
  background(255);
  for (int i = 0 ; i < images.length; i++)
  { 
    images [i] = loadImage("IMG_0" + (701 + i) + ".JPG");
    alpha = loadImage("alphamask.gif");
    images [i].mask(alpha);
    images [i].resize(100, 100);
    println(i);
  }
  
  
} 
void draw()
{
  if(mousePressed){
     int counter = frameCount % 19;
  image(images[counter], mouseX - 50, mouseY - 50);
  }
}

Homework 4

For the fourth homework, we had to work with a soundboard, which plays different audio files depending on where you click on an image or which number you choose. The following code includes a atLocation function which checks for circular areas and a variable called playingLocation, which shows an ellipse for the length of the playing soundfile at its position.

import ddf.minim.effects.*;

Minim minim;

PImage img1;
int n=9;
int activeLocation = -1;
AudioPlayer[] players = new AudioPlayer[n];
int[][] locations = {
  {160, 140, 20},
  {220, 220, 20},
  {70, 300, 20},
  {300, 235, 20},
  {230, 530, 20},
  {110, 520, 20},
  {330, 470, 20},
  {243, 96, 20},
  {138, 433, 20},
};


void setup() {
 minim = new Minim(this);
 size(400,600);
 img1 = loadImage("img2.png");
for(int i=0; i<n; i++){
 players[i] = minim.loadFile("sound" + (i+1) + ".mp3");
}
 
}


void draw() {
  image(img1,0,0,400,600);
  fill(0,150);
  noStroke();
  for(int i=0; i < locations.length; i++){
   int[] loc =locations[i];
  
  int x= loc[0];
  int y= loc[1];
  int r= loc[2];
 
 if(atLocation(x,y,r)){
  activeLocation = i;
  ellipse(x, y, 2*r, 2*r);
  }
 if(playingLocation(i)){
  ellipse( x,y,2*r,2*r);
 }
  }
 }     
 boolean atLocation(int x, int y, int r){
      return dist(x,y,mouseX,mouseY)<r;
  }
  
  boolean playingLocation(int i){
   return players[i].isPlaying(); 
  }

void mousePressed(){
 if(activeLocation !=-1){
  for (int i=0; i<n; i++) {
   players[i].pause(); 
  }
  println("Sound number " + (activeLocation + 1));
  println(mouseX, mouseY);
  players[activeLocation].rewind();
  players[activeLocation].play();
 } 
  
}

void keyPressed(){
  for(int i=0; i<n; i++){
    players[i].pause();
  }
  int i = (key - '1');
  
  if(i>= 0 && i<n){
  println("Sound number " + (i+1));
  players[i].rewind();
  players[i].play();
  }
}
