Hi

I was writing something like this for a larger sketch and wondered if there is a way to increase the framerate? Is there a better way to recalculate and update all pixels?

1. PGraphics pg;
   
   void setup(){
     size(900,450);
     noFill();
     pg = createGraphics(width, height, P2D); 
   }
   
   void draw(){
    
     float sinFactor = width/(mouseX+1);
     float cosFactor = height/(mouseY+1);
    
     background(0);
     pg.loadPixels();
     for(int i = 0; i < width; i++){
       for(int j = 0; j < height; j++){
         color p = color( ( 127.5 * sin(radians(j)*sinFactor) * cos(radians(i)*cosFactor) ) + 127.5 );
         pg.pixels[j*width+i] = p;
       } 
     } 
     pg.updatePixels();  
    
     image(pg,0,0);
   
     println(frameRate);
   }
