currently happily under construction :)

realtime video collage with p5.js

This prototype grabs parts of the live video and draws them randomly, like collage, on the stage. Check out the running ONLINEDEMO.

let w,h;
let video;

let allTiles = [];

// set your video size here > smaller is better
let video_width = 640;
let video_height = 480;

  createCanvas(window.innerWidth, window.innerHeight);
  w = window.innerWidth;
  h = window.innerHeight;
  
  video = createCapture(VIDEO);
  imageMode(CENTER);
  video.size(video_width, video_height);
  video.hide();
  
   drawingContext.shadowBlur = 8;
   drawingContext.shadowColor = color(0);

  // create some tiles to play with
   for (let i = 0; i < 16; i++) {
     
    // make tile random sized 
     let rsize = int(random(40,200));
     
     let nt = new aTILE(i,rsize);
     
     // random positon of each tile
     nt.x = random(-200,200)+w/2;

     nt.sx = random(video_width-rsize);
     nt.sy = random(video_height-rsize);
     
     
     allTiles.push(nt);
     
   }
