V i ewpor t Clippi ng—Interactively sets a near and
far range for the v iewpor t. Geometry within the
viewport clipping range is displayed. Faces outside
the range are not displayed. This is useful in
complex scenes where you want to work on details
that are obscured from view. Turning on viewport
clipping displays two yellow slider arrows on the
edge of the viewport. Adjusting the lower arrow
sets the near range, and the upper arrow sets the
far range. Tick marks indicate the extents of the
viewport. Viewport Clipping can also be turned
on and off in the
Viewport Configurat ion dialog
(page 3–896)
.
Texture Correction—Redraws the viewport using
pixel-interpolation (perspective corrected).
Note: This is for the software display driver only.
If you are using the OpenGL or Direct3D display
mode, texture correction is automatic.
Disable V i ew—Disables the active viewport. A
disabled view por t behaves like any other viewp or t
while it is active. However, when you change the
scene in another view por t, the v iew in the disabled
viewport does not change until you activate it. Use
this function to speed up screen redraws when you
are working on complex geometry.
