MainLoop

CubicVR.MainLoop

The MainLoop provides a simple way to wrap your main drawing loop.

It also provides a CubicVR.Timer as well as the WebGL Context as two parameters to your callback respectively. MainLoop will use the window.*requestAnimationFrame() methods to manage framerate where available and fallback to setInterval() otherwise.

Constructor:

MainLoop( loopCallback, doClear )

Parameters:

• loopCallback : Your main draw loop function, it will receive the parameters loopCallback( timer, gl ) for a CubicVR.Timer and the WebGL Context.
• doClear (optional) : Whether or not to call gl.clear( DEPTH_BUFFER | COLOR_BUFFER ) before each frame, default: true.

Returns:

If called with new MainLoop(..) will return a MainLoop instance, none if used as singleton.

Typical Usage:

var myloop = new CubicVR.MainLoop(function (timer,gl) {  
   // ...  
});

or

CubicVR.MainLoop(function (timer,gl) {  
   // ...
});
