dtcTransformCaps

One of the members of the D3DTRANSFORMCAPS structure, specifying the transformation capabilities of the device.

bClipping

TRUE if the device can perform 3D clipping.

dlcLightingCaps

One of the members of the D3DLIGHTINGCAPS structure, specifying the lighting capabilities of the device.

dpcLineCaps and dpcTriCaps

D3DPRIMCAPS structures defining the device's support for line-drawing and triangle primitives.

dwDeviceRenderBitDepth

Device's rendering bit-depth. This can be one of the following DirectDraw bit-depth constants: DDBD_8, DDBD_16, DDBD_24, or DDBD_32.
