Viewport Parameters group

Use Dual Planes

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 setting provides the fastest redraws under normal circumstances. If your assigned display driver doesn't support dual planes, this option is not available.

Turn 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 viewport needs to be redrawn anyway).

Show Vertices As Dots

When on, 3ds Max displays vertices in mesh and patch objects as small, solid-color squares, whose size you can set with the Size parameter. When off, the vertex display is a tick mark.

Size

Lets you specify the vertex size displayed in the viewports. Range=2 to 7. Default=2.

Handle Size

Lets you specify the display size for handles attached to patch vertices and spline vertices. Range=2 to 7. Default=3.

Draw Links as Lines

Displays the hierarchical links between parent and child objects as plain lines, rather than shapes when Display panel Link Display rollout Display Link is on.

Backface Cull on Object Creation

Determines whether to display faces with normals pointing away from view. When on, you see through the wireframe to the backfaces. This option applies to wireframe viewport displays only. In most cases, keep this switch enabled. However, when modeling with NURBS surfaces, which consist of single-sided planes, it's easier to view the geometry from all angles when backface culling is off.

• This control affects only the created objects, and you can reverse the effect on each object by changing the Backface Cull setting in the Object Properties dialog for that object.You might turn off Backface Cull On Object Creation before creating your NURBS, and then turn it on again when your finished.
• You can globally change the display of backface culling in the viewports by turning on Force 2-Sided on the Rendering Method panel of the Viewport Configuration dialog.

Attenuate Lights

Turns the display of attenuation effects on or off from start to end in the interactive viewport renderer. When off, attenuated lights behave as though unattenuated. Default=off.

Mask Viewport to Safe Region

By default, the viewport area outside the outermost safe frame displays the contents of the viewport. When this switch is on, that area is left blank.

Update Background While Playing

Turns on the updating of bitmaps in the viewport background when you play an animation. This capability lets you check your action against a 2D rotoscoped background, even if your animation plays at 1 frame per second. When on, an IFL file, AVI file, or MOV file updates on each frame when you click the Play button. To use this feature, turn off the real-time switch on the Time Configuration dialog.

The viewport updates not only when you click Play, but also when you drag the time slider.

Filter Environment Backgrounds

Affects the background displayed in the viewport only when the Viewport Background dialog Use Environment Background switch is on.

When you turn on Filter Environment Backgrounds, the environment background is filtered in the viewport, resulting in an antialiased image. When you turn it off, the background image is not filtered, resulting in an aliased, pixelated image.

Note the following:

• Filtering slows down the recalculation of the viewport background image about 30 to 40 percent. Unless you really need that smooth display, it's best to leave the option off.
• This option doesn't affect the rendered background image, and doesn't effect the viewport backgrounds when you turn on Use Environment Background.

Low Res Environment Background

Reduces the size of the environment background map by half, and then magnifies it to the size needed for the viewport. This results in a chunkier, pixelated appearance, but speeds the rendering in the viewport by four times (because it halves the width and the height of the original image).

TipUnless you need fine detail in your environment background, keep this switch enabled.

Display World Axis

When on, displays a world axis in the lower-left corner of all viewports. Default=on.

Grid Nudge Distance

Sets the nudge distance for the Nudge Grid Down and Nudge Grid Up functions, which you can use to move an active grid helper object into position. See To nudge a grid object up or down:.

Non Scaling Object Size

Sets the display size of cameras, lights, and other nonscaling objects. Default=1.

Ghosting group

Ghosting Frames

Specifies the number of ghost images that appear before and after the current frame when you choose Show Ghosting from the Views menu. If you display ghosts both before and after the current frame, the total number of ghosts is twice this number.

Display Nth Frame

Specifies the number of frames between the appearance of each ghost. The smaller this number, the closer the ghost images appear to each other.

Ghost Before Current Frame

Displays only ghost images that occur before the current frame. This makes the ghosts trail the object.

Ghost After Current Frame

Displays only ghost images that occur after the current frame.

Ghost Before and After

Displays ghosts both before and after the current frame.

Ghost in Wireframe

Displays ghosts in black wireframe in shaded viewports. When off, the ghosts appear as shaded objects, using the same colors as the wireframe ghosts.

Show Frame Numbers

Displays a frame number in the upper-left corner of each frame.

Mouse Control group

Middle Button Pan/Zoom

Sets the middle mouse button to pan in the viewport if you have a three-button mouse. If you have a Microsoft Intellimouse, you can also roll the middle wheel to zoom the viewport.

To Zoom with a three button mouse, press Ctrl+Alt and drag the center button.

NoteBy default, the Intellimouse slows the speed of the mouse when you hold down the wheel button. You can increase the mouse speed in the Mouse Properties dialog in the Windows Control Panel. Choose the Wheel tab, click the Settings button in the Wheel Button group, and turn the slider up to Fast.

Stroke

Assigns command shortcuts to stroke patterns applied by dragging with the middle mouse button. See Strokes.

Zoom About Mouse Point (Orthographic)

When on, viewports zoom about the point where you click the mouse. When off, viewports zoom about the center of the view. Applies to orthographic viewports only.

Zoom About Mouse Point (Perspective)

When on, viewports zoom about the point where you click the mouse. When off, viewports zoom about the center of the view. Applies to perspective viewports only.

Right Click Menu Over Selected Only

Limits the right-click menu display over a selected object. Default=off.

When this option is off, you can right-click anywhere in the viewports to display a menu.

Wheel Zoom Increment

Determines the sensitivity of the zoom when you use the wheel on the mouse. Increase sensitivity up to a maximum value of 100 or reduce it to a minimum of 0.01. Default=1.0.

Display Drivers group

Currently Installed Driver

Displays the name of the currently installed driver.

Choose Driver

Displays the Display Driver Selection dialog. Use this dialog to choose a different display driver.

Configure Driver

Displays a Configure Driver dialog, where you can change the options for the current display driver.

(Not available for Nitrous viewports: All Nitrous settings are on the Viewport Configuration dialog.)
