The Direct3D device that an application creates must correspond to the capabilities of the hardware on which the application is running.
These are provided by third parties to emulate particular devices - for example, developmental hardware that has not yet been released. The most common way to take advantage of these devices is to use the hal device for shipping applications, and the reference device for feature testing. Software and reference devices are represented by software drivers, and the hal device is represented by a hardware driver. You can think of these devices as two separate drivers. A hal device with hardware-accelerated rasterization and shading with both hardware and software vertex processing.Determining Hardware Support (Direct3D 9)Īrchitecturally, Direct3D devices contain a transformation module, a lighting module, and a rasterizing module, as the following diagram shows.ĭirect3D currently supports two main types of Direct3D devices:.
In addition, a Direct3D device performs transformations and lighting operations and rasterizes an image to a surface. It encapsulates and stores the rendering state. A Direct3D device is the rendering component of Direct3D.
