是否可以使用five.grok在Plone 4.1中注册portlet？(Is it possible to use five.grok to register portlets in Plone 4.1?)

 每个动画完成后，您必须调用root.render函数。 因此，请在root.render函数中调用root.animate函数。 喜欢这个 - 
 
var root = this;

    animate: function() {

            // Development
            console.log("init Animate");

            requestAnimationFrame( root.animate );

            root.mesh.rotation.x += .05;
            root.mesh.rotation.y += .05;
            root.render();
        }, 
 
 另外，我不知道你为什么需要LoadingManager 。 我不认为它应该在animate函数中使用，它将被重复调用。 
 
 编辑：您必须在函数之外定义root变量。 您已在每个函数中定义了此变量。 相反，你必须在CubeController定义它。 

You have to call the root.render function after each animation is done. So call the root.render function in your root.animate function. Like this - 
 
var root = this;

    animate: function() {

            // Development
            console.log("init Animate");

            requestAnimationFrame( root.animate );

            root.mesh.rotation.x += .05;
            root.mesh.rotation.y += .05;
            root.render();
        }, 
 
Also, i dont know why do you need LoadingManager. I dont think it should be used in the animate function which will be called repeatedly.
 
Edit: You have to define the root variable outside of the functions. You have defined this variable in every function. Instead you have to define it in the CubeController.
