Rendering Loop ala vendor.js

renderloop-vendor.js

// array of functions for the rendering loop
var onRenderFcts = [];
	
// Here you add your functions to the rendering loop.
// They will be executed in-order once per requestAnimationFrame()
onRenderFcts.push(function(now, delta){
	// now is the absolute time in millisecond
	// delta is the delay between now and the last iteration 
  
	// put your code here.
})

// -----------------------------------------------
// ... you may put more functions here
// -----------------------------------------------

// run the rendering loop
var previousTime = performance.now()
requestAnimationFrame(function animate(now){

	requestAnimationFrame( animate );

	onRenderFcts.forEach(function(onRenderFct){
		onRenderFct(now, now - previousTime)
	})

	previousTime	= now
})

Should it be previousTime = now on the last line?

@angryobject good catch! corrected

nice!
