MIDI Time Slider Control Setup Dialog 847
Tex el Lookup—
Specifies whether to use the nearest
pixel (page 3–995), to linearly interpolate the pixel
value from the four closest texels (page 3–1021),or
to use anisotropic filtering. Using the nearest pixel
is faster, but u sing texels produces a higher-quality
display. The Anisotropic filter compensates for
the distortion caused by the difference in angle
between the texture polygon a nd the plane of the
screen. Default=Nearest.
MipMap Look up—Specifies whether to use one
version of the texture map (None) or to interpolate
between a pyramid of progressively smaller 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. Defa ul t=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 aliasing, but it is time
consuming if the texture-mapping hardware is not
accelerated.
Dir ectX 10 Ver s ion
When DirectX 10 is active on your system, the
dialog uses a simpler, more straightforward
interface:
The par ameters are identical to t hose with the
same names listed previously in this topic, and one
settin g has been added:
Maximum number of active lights—Lets you define
the number of act ive lights used in the lighting
calculations. Setting this too high can affect
performance.
