hardware-specific custom code. Default=on.
Use W iref r ame Faces—When on, makes wireframe
display accessible to hardware acceleration.
Default=on.
This option is intended to allow display-card

displays in a way that is specific to the underly ing
display hardware. Che ck with your display-card
manufacturer to see if enabling this option will
yield faster wireframe rendering with your display
card.

Enable Anti-Aliased Lines in Wirefra me
Views—
Draws lines slightly thicker and much
smoother. This is best used for wireframe-only
views, and especially if you’re making a preview of
wireframe objects.
Background Texture Size—Unlike the Software
Display driver, which u ses bitmaps to display
viewport backgrounds directly, the OpenGL driver
uses a texture-mapped background rectangle.
Thisallowsforsmootherzoomsandpansin
orthographic views and can take less memory than
the direct bitmap method. However, background
bitmap resolution ma y be lost. Increase the
resolution if you’re using a maximized viewport
to digitize.
Download Tex ture Size—Lets you choose the size of
the texture map that’s downloaded to the driver
for texture-mapped scene objects. Larger maps
look better, but use more display card memory.
Note: When Match Bitmap Size As Closely as
Possibleison,thesebuttonsareoverridden,
however they are still available. The value is still
used when procedural textures are converted to
bitmaps for viewport texture display.
Match B itmap S ize as Closely as Possible—To allo w
the viewp ort to show actua l texture resolutions,
bitmaps are individually resized before they are
downloaded to the driver. This means that small
bitmaps don’t get overexpanded 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 dow n to this size) and
no smaller than 32 x 32 (or they will be sca led up
to this size). Default=off.
Texel Lookup—Specifies whether to use the nearest
pixel (page 3–995) or to linearly interpolate the
pixel value from the four closest texels (page
3–1021). Using the nearest pixel is faster, but
using texels produces a higher-quality display.
Default=Nearest.
Mi pMa p 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 lo okup is done
on the map level nearest the ideal one, and w ith
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 aliasing, but it is time
consuming if the texture-mapping hardware is not
accelerated.
