RenderController

SomeView.js

SomeView.prototype.show = function() {
    var prevAnimation = {
        transition: {},
        transform: {}
    }
    
    var thisAnimation = {
        transition: {},
        transform: {}
    }
    
    app.controller.show(this, thisAnimation, prevAnimation, callback)    
}

A lot depends on your use case.

Do you want individual renderables to be automatically removed? (in which case you would return a variable-length array of the renderables with their transforms in a .render function)

Does your entire Scene (made up of several renderables) transform in unison, or do you want atomic control of each renderable in your Scene? The former only requires RenderController.
