Index buffers are a way to reduce the amount of gpu memory required to store a model’s attribute data by allowing duplicate vertex data to be removed from the Vertex Buffer. An Index Buffer acts like an array of pointers into the Vertex Buffer, allowing vertex data to be reused by multiple triangles during rendering.
A staging buffer is used in the process of transferring data from the host (cpu) to the device (gpu), and is a temporary location to hold data so that it can then be transferred to more optimal (faster) device memory.
In this tutorial we update the model class to support index buffers, and use staging buffers to transfer the model data to device optimal memory.
