However, redrawing takes some time. Default=on.
Ifyour3dsMaxdisplayeasilybecomesmessyor
"corrupted," turn this option on and then redraw
view por ts by choosing Views > Redraw All Views
(the default keybo ard shor tcut for this is the 1 key
on the n umeric keypad).
This option has two subordinate options. How
you should set them depends on how the display
card handles its back buffer, which is used for
refreshing the screen. Turn on one or the other,
as appropriate.
•
Redraw In Maximized V iewport—If, after
updating the screen, the display card destroys
the back buffer
only when there’s a single
viewport, turn on this sub-option. The
Direct3D driver redraws the scene when a
single view port is visible, but doe sn’t have to
redraw when multiple viewports are visible.
Default=off.
•
Redraw In UnMaximized V iewpor ts—If, after
updating the screen, the display card destroys
thebackbufferwhenmultipleviewportsare
visible, turn on this sub-option. Default=off.
Allow Dual Plane Support—Uses the front/back
plane system when redrawing the viewport. The
selected object is manipulated in the front plane
and is redrawn , while other objects remain on
the back plane and are not redrawn. This default
settingprovidesthefastestredrawsundernormal
circumstances. If your assigned display drive r
doesn’t support dual planes, this option is not
available.
Tu rn off this setting to improve redraw speed if you
are rotating the whole scene or moving a camera
through the scene (usually situations in which the
whole v iewport needs to b e redraw n anyway).
Use I ncremental S cene Upda tes—Redraws only
thosesceneobjectsthathavechanged,orthat
intersect a region changed by another moving
object. When tur ned off, the entire scene is
redrawn for each new frame. Default=on.
If your 3ds Max display becomes messy or
"corrupted" as a result of incremental updates,
turn this option off and then redraw viewports by
choosing Views > Redraw All Views (the default
keyboard shortcut for this is 1 on the numeric
keypad).

Enable Antialiased Lines in Wireframe V iews—Draws
lines slightly thicker and much smoother. This is
best used for w ireframe-only views, especially if
you’re making a preview of wireframe objects.
Background Texture Size—Unlike the software
display driver, which uses bitmaps to display
viewport backgrounds directly, the Direct3D
driver uses a texture-mapped background
rectangle. Thisallowsforsmootherzoomsand
pans in orthographic views and can take less
memory than the direct bitmap method. However,
background bitmap resolution may be lost.

Match B itmap Size as Closely as Possible—Displays
background at full resolution. This allows the
viewport to behave like the
rendered frame
window (page 3–5)
, in regards to zoom and pan.
Default=off.
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

however they are still available. The value is still
used when procedural textures are converted to
bitmaps for viewport texture display.
