Hausaufgabe I

  • Diese Fotos haben wir zunächst als Slideshow animiert.

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");

void draw()
