Alternative to get() for faster performance?

Hello,

This topic inspired me!

Something I worked on:

Example of random tiling < Click here to see code!

// Pixel Manipulation 
// v1.0.0
// GLV 2021-05-30

let img;
let cap;

function setup() 
  {
  createCanvas(640, 480); // Set to video size
  
  img = createGraphics(width, height);

  pixelDensity(1);    
  img.pixelDensity(1);
  
  cap = createCapture(VIDEO);
  cap.hide(); 
  
  //d = pixelDensity(); // Future! See references.
  }

function draw() 
  { 
  cap.loadPixels();
  img.loadPixels();
  
  tilesX = 10;
  tilesY = 10;
  
  //samples = map(mouseX, 0, width, 0, 2000);
  samples = 200; 
  
  for (let i = 0; i<samples; i++)
    {
    x = (random(width))| 1;  // Converts to int
    y = int(random(height)); // Converts to int 
      
    let loc = x + y*cap.width;
  
  // Copy a tile from capture to pixels     
    for (let xt = x; xt < x+tilesX; xt++) 
      {
      for (let yt = y; yt < y+tilesY; yt++) 
        {        
        let loct = (xt + yt*cap.width)*4;
        
        img.pixels[loct + 0] = cap.pixels[loct + 0];  //r
        img.pixels[loct + 1] = cap.pixels[loct + 1];  //g
        img.pixels[loct + 2] = cap.pixels[loct + 2];  //b
        img.pixels[loct + 3] = cap.pixels[loct + 3];  //a
        }
      }
    }    
    
  img.updatePixels();
  image(img, 0, 0);
  
  // Display data
  fill(255);
  stroke(1);
  textSize(18);
  text(frameRate()|1, 10, 20);
  text(samples, 10, 40);
  }

A very cool effect!

:)
