HAL Device

  • Article

The primary device type is the hardware abstraction layer (HAL) device, which supports hardware accelerated rasterization and both hardware and software vertex processing. If the computer on which your application is running is equipped with a display adapter that supports Microsoft® Direct3D®, your application should use it for 3-D operations. Direct3D HAL devices implement all or part of the transformation, lighting, and rasterizing modules in hardware.

Applications do not access 3-D cards directly. They call Direct3D functions and methods. Direct3D accesses the hardware through the HAL. If the computer that your application is running on supports the HAL, it will gain the best performance by using a HAL device.

To create a HAL device from C++, call the IDirect3D8::CreateDevice method, and pass the D3DDEVTYPE_HAL constant as the device type. For details, see Creating a Device.

Note   Hardware devices cannot render to 8-bit render-target surfaces.
