as the Material Editor or Track View. However, redrawing takes some time. Default=on. If your 3ds Max display easily becomes messy or "corrupted," turn this option on and then redraw viewports by choosing Views > Redraw All Views (the default keyboard shortcut for this is the "1" key). 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. Full Screen SwapBuffers Destroys Back Buffer 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 OpenGL driver redraws the scene when a single viewport is visible, but doesn't have to redraw when multiple viewports are visible. Default=off. Windowed SwapBuffers Destroys Back Buffer If, after updating the screen, the display card destroys the back buffer when multiple viewports are visible, turn on this sub-option. Default=off. Use Triangle Strips Strips all geometric data before sending it to the driver. In some cases, such as when topology is constantly changed, the time taken to strip the geometry can cause a slowdown instead. In such cases, turn off this option. Otherwise, leave it on for speed. Default=on. This option has one subordinate option: Display Wireframe Objects Using Triangle Strips 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 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). Use Incremental Scene Updates Redraws only those scene objects that have changed, or that intersect a region changed by another moving object. When off, the entire scene is redrawn for each new frame. Default=on. If the 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 the ` [accent grave] key). 7798 | Chapter 26 Customizing the User Interface
