#include "CAS_Renderer.h"

//
// This is the main class, it manages the state of the sample and does all the high level work without touching the GPU directly.
// This class uses the GPU via the the SampleRenderer class. We would have a SampleRenderer instance for each GPU.
//
// This class takes care of:
//
//    - loading a scene (just the CPU data)
//    - updating the camera
//    - keeping track of time
//    - handling the keyboard
//    - updating the animation
//    - building the UI (but do not renders it)
//    - uses the SampleRenderer to update all the state to the GPU and do the rendering
//
