Hausaufgabe I

• Diese Fotos haben wir zunächst als Slideshow animiert.

Beispiel in ProcessingJS

Processing v3.0.0 Quellcode:

int numFrames = 9;  // The number of frames in the animation
int frame = 0;
PImage[] images = new PImage[numFrames];
 
void setup()
{
  size(720, 405);
  background(0, 0, 0);
  
  images[0] = loadImage("https://c1.staticflickr.com/1/636/23689341201_539535fb38_c.jpg");
  images[1] = loadImage("https://c1.staticflickr.com/1/691/23689340691_5c89b21cf0_c.jpg");
  images[2] = loadImage("https://c1.staticflickr.com/6/5740/23476083740_2ff98481ed_c.jpg");
  images[3] = loadImage("https://c1.staticflickr.com/1/751/23689339091_cb6ce2b439_c.jpg");
  images[4] = loadImage("https://c1.staticflickr.com/6/5668/23143601864_d6a4f33a88_c.jpg");
  images[5] = loadImage("https://c1.staticflickr.com/1/707/23745637836_6f3068aa50_c.jpg");
  images[6] = loadImage("https://c1.staticflickr.com/1/613/23771753205_e8dff07d81_c.jpg");
  images[7] = loadImage("https://c1.staticflickr.com/1/722/23771752525_984f6d44d7_c.jpg");
  images[8] = loadImage("https://c1.staticflickr.com/6/5823/23745638646_0bc4248d58_c.jpg");

  frameRate(0.75);
}

 
void draw()
{
  frame = (frame) % numFrames;  // Use % to cycle through frames
  image(images[frame], 0, 0, 720, 405);
   
  if (frame<9)
  { frame++;
  }
  else frame = 0;
}

• Danach wurden die Fotos in ein Raster gesetzt.
