Fullscreen / resize with the window about flat-surface-shader HOT 2 OPEN

For resizing the plane, I found it best to use container.offsetHeight:

   function resize() {
         renderer.setSize(screen.availWidth, container.offsetHeight);
   }

from flat-surface-shader.

you could try this:
instead of

var geometry = new FSS.Plane(600, 400, 6, 4);

put

var geometry = new FSS.Plane(screen.availWidth, screen.availHeight, 6, 4);
