Mapping
Mapping, or placing, an image onto an object. Images of
realistic surfaces are placed on 3D models to create a
richer and more complex visual effect.
Trilinear
Filtering
Sampling method used to produce the most realistic
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.
