bitmaps are individually resized before they are
down loaded to the driver. This means that small
bitmaps don’t get o verexpanded and large bitmaps
retain their resolution (but potentially use a lot
more video RAM).
Note: Bitmaps can be no larger than 4000 x 4000
pixels (or they will be scaled down to this size) and
no smaller than 32 x 32 (or they will be scaled up
to this size). Default=off.
Tex el Look up—Specifies whether to use the nearest
pixel (page 3–1089) ,tolinearlyinterpolatethe
pixel value from the four closest
texels (page
3–1115)
, or to use anisotropic filtering. Using the
nearest pixel is faster, but using texels produces
a higher-quality display. The Anisotropic filter
compensates for the distortion caused by the
difference in angle between the texture polygon
and the plane of the screen. Default=Nearest.
MipMap Lookup—Specifies whether to use one
version of the texture map (No n e) or to interpolate
between a pyramid of progressively sma l ler maps.
With Nearest chosen, the texel lookup is done
on the map level nearest the idea l one, and with
Linear, the texel values from the two closest map
levels are interpolated. Default=None.
Note: When both Texel and MipMap lookup are
set to Linear, a true trilinear weighting of 8 texel
values is used for a single pixel display. This is very
accurate and helps eliminate a liasing, but it is time
consuming if the texture-mapping hardware is not
accelerated.
