Scale the whole screen content to the back

Processing Coding Questions

i want to scale the screen content slowly to the (pseudo)back, using a 2d scale (shrinking).
here is what i have as start out;

int siz = 66;

 void setup(){
   size(800,600);
}
 
void draw(){
  ellipse((int)random(width), (int)random(height),siz,siz);
}

this constantly created content should scale (seemingly) backwards, endlessly as new objects are generated…

would be more easy, but only if centered,

__

float zoom=100;
void setup(){}
void draw() {
  translate(width/2,height/2);
  circle(0,0,zoom);
  zoom*=0.95;
}

might be other way.

thanks for getting back to my question!
well, i mean the animation;

  • how to separate a certain object animation (shrinking) to generate them again and again to the stage.
    i’ve seen something like this using a PVector[] array which seemed great, but could get the syntax right…

not understand, but with

  zoom*=0.95;
  if ( zoom < 0.05 ) zoom = 100;

it runs again and again
if that is what you call animation?

this zoom* is good either. thank you!

how can i make each circle zoom animation from beginning to end?

float zoom=100;
int count;
void setup(){
  size(555,555);
}

void draw() {
  count+=1;
  
  if(count==10){
    elli((int)random(width),(int)random(height));
    count=0;
  }
}

void elli(int x, int y){
  //translate(width/2,height/2);
  ellipse(x,y,zoom,zoom);
  zoom*=0.95;
}
