ATI Technologies RADEON MAC EDITION, 107-40214-20 manual Texture, Mapping, Trilinear, Buffer

Texture	Mapping, or placing, an image onto an object. Images of
Mapping	realistic surfaces are placed on 3D models to create a
	richer and more complex visual effect.
Trilinear	Sampling method used to produce the most realistic
Filtering	looking 3D objects. Trilinear filtering averages one of the
	bilinear filter MIP Map levels along with the standard MIP
	Map samples.
z-buffer	A z-buffer is an area of off-screen memory used to hold
	“depth” information. For each dot, or pixel, in the display
	buffer, there is a corresponding dot in the z-buffer which
	holds the depth (z) value for the display pixel. The depth
	data helps the ATI accelerator card decide what 3D objects
	are in front off other 3D objects.
	The larger the 3D window, the larger the z-buffer is in
	memory.
