function pointer
7
What is the purpose of the DirectDraw component of DirectX?
It is the primary rendering and 2D bitmap engine that controls the video display

What is a reference rasterizer better known as? and what does it do? and what does it allow?
a REF device (1/3 credit)

D3DPOOL_DEFAULT
D3DPOOL_MANAGED
D3DPOOL_SYSTEMMEM

11
What parameter must be set to false to have a full-screen window?
windowed
12
True or False

False
13
COM is a general specification that can be followed with any language on any machine, but one rule must be followed...what is that rule?
The binary image of the COM object must be that of a virtual class generated by a Microsoft VC compiler
14
Vertex processing occurs in two different formats, they are_________and____________.
hardware and software
15
What does HEL stand for and when is it used?
Hardware Emulation Layer
used when the hardware doesn't support the feature that you are requesting
16
What does HAL stand for? and what is it? and when is it used?
Hardware Abstraction Layer
set of device-specific code that instructs the device to perform an operation It talks directly to the hardware.
HAL is used when the feature you’re requesting is supported directly by the hardware and thus is accelerated.
