你可以在使用硬件抽象层设备的任意时间绑定软件和硬件顶点处理，该唯一设备同时支持硬件和软件顶点处理。

You can toggle between software and hardware vertex processing at any time when using the Hal device, the only device type that supports both hardware and software vertex processing.

当设备被模拟(比如虚拟网络适配器)时，模拟提供一个抽象层以抽象物理硬件。

When devices are emulated, such as virtual network adapters, the emulation provides a layer to abstract away the physical hardware.
