Part I: Getting Started with 3ds Max

FIGURE 2.31
The image on the left was rendered using the Sub Region option; the right image used the Blowup Region.

You can learn more about Render Types and the Rendered Frame Window in Chapter 23, “Rendering a Scene and
Enabling Quicksilver.” n
The Virtual Viewport is a feature that lets you zoom in and pan within the viewport image using the
numeric keypad. This feature is available only if you are using the OpenGL display driver. You can check to
see which display driver you are using by selecting Help ➪ About 3ds Max. This command opens a credits
screen that lists the current driver. You can change the current display driver in the Viewport panel of the
Preference Settings dialog box.

If you have OpenGL set as the current display driver, then you can select Use Virtual Viewport to display
the viewport in the area to the right. Using the Zoom, X, and Y Offset values, you can specify where the vir-
tual viewport looks or you can drag the rectangular outline in the visible screen to the right.
Once the Virtual Viewport feature is enabled, you can use the divide key (/) on the numeric keypad to turn
the virtual viewport on and off. Use the plus (+) and minus (–) numeric keypad keys to zoom in and out,
and use the 2, 4, 6, and 8 keys on the numeric keypad to pan within the virtual viewport.

Caution
The Virtual Viewport feature is available only if you are using the OpenGL driver. If you’ve specified either the
Software Z-Buffer or the Direct X driver, then this option isn’t available. n

Viewing statistics
The Statistics panel, shown in Figure 2.32, lets you display valuable statistics in the viewport window.
These statistics can include Polygon Count, Triangle Count, Edge Count, Vertex Count, and Frames Per
Second. You can also select to view these statistics for all the objects in the scene (Total), for just the
selected object, or for both. You can toggle statistics on and off for the active viewport using the 7 key.
By enabling the Show Statistics in Active View option, the selected statistics are overlaid on the active view-
port, as shown in Figure 2.33.
