Interesting Texture #2

Actionscript:
  1. var canvas:BitmapData = new BitmapData(1000,1000,false, 0x000000);
  2. addChild(new Bitmap(canvas));
  3. scaleX = scaleY = .5;
  4.  
  5. var w:int = canvas.width;
  6. var w10:int = w * 40;
  7. var size:int = canvas.width * canvas.height;
  8. for (var i:int = 0; i<size; i++){
  9.     var xp:int = i % w;
  10.      
  11.     var yp:int = int(i / w);
  12.     var c1:int = (255/8) * (Math.cos(xp* Math.PI/180 * 2) + Math.sin(yp*(xp + 200)/w10));
  13.     if (c1 <0) c1 = 256 - c1;
  14.     c1 = (c1 <<1 | c1) ;
  15.     canvas.setPixel(xp, yp, c1 <<15 | c1 <<7 | c1 );
  16. }
  17. var m:Matrix = new Matrix();
  18. m.scale(1,-1);
  19. m.translate(0,canvas.height);
  20. var clone:BitmapData = canvas.clone();
  21. canvas.draw(clone, m, null, BlendMode.SUBTRACT);
  22. clone.draw(canvas);
  23. clone.applyFilter(clone, clone.rect, new Point(0,0), new BlurFilter(10,10,1));
  24. canvas.draw(clone, null, null, BlendMode.ADD);

Randomly bit shifting on this one is actually getting a good deal of millage.. I know I can easily optimize so that it works in realtime - could even be done in pixelbender... but going to play a bit more first before I optimize....
