ATI Technologies 107-40214-20 Color Depth, Fog, Frame, Buffer Gouraud, Shading, MIP Map, Memory

Color Depth	Color depth is the number of color shades available on
	your display. The color depth of your monitor usually
	includes; 256 colors (8-bpp), Thousands of colors
	(16-bpp), and Millions of colors (32-bpp), and is also
	measured in bits per pixel (bpp). You can switch your
	color depth using the ATI Popup Menu, Apple’s Control
	Strip, or the Monitors control panel. Higher bit-depths
	require more display buffer memory.
	Note: The ATI 3D Accelerator only functions in
	Thousands and Millions of colors modes.
Fog	The blending of an object with a fixed color as objects or
	pixels increase distance away from the viewer.
Frame	Memory buffer used to store the image being displayed.
Buffer
Gouraud	One of the more sophisticated shading methods used to
Shading	produce a smooth lighting effect across a 3D object. A
	specific color is used at each vertice of a triangle or
	polygon, and interpolated across the entire face.
MIP Map	Multum In Parvum (Latin) means “many in one.” It is a
	method of increasing quality of a texture map by storing
	multiple resolutions of the same image and dynamically
	switching between them depending on the size and depth
	of the object being textured.
Offscreen	An area of memory used to preload and place images so
Memory	that they can be quickly drawn on the screen. Offscreen
	memory refers to all the memory on your ATI accelerator
	card that is not taken up by the front buffer, which holds
	the display screen that you see.
Pixel, Pel	Picture element. Smallest addressable area of the
	computer screen. Pixels on computer displays are square;
	pixels on NTSC televisions have a 4:3 aspect ratio.
Refresh Rate	Also referred to as “vertical refresh rate”. The rate at
	which a monitor or television can redraw the screen from
	top to bottom. NTSC television systems have a refresh rate
	of approximately 60 Hz (but only draw one-half of the
	video frame in one pass); computer displays typically have
	refresh rates of 75 Hz or more. At a refresh rate of 70 Hz
	and lower, screen flicker is often noticeable.
Specular	The bright, usually small, intense light reflected from a 3-
Highlight	D surface with a high refraction value.
