In the Preferences window, the OpenGL® preference settings consist of the following:

The Pixel Format preference settings let you set default values for the Viewer window display. The following table describes the Pixel Format preference settings.
| Pixel Format settings | Description |
|---|---|
| Force Pixel Format | The Force Pixel Format value is an index of the Viewer window pixel format. For example, you can enter a value if you want to force your display to show Anti-Aliasing. Double-click the field to enter a value. This setting only affects the display of the Viewer window. The default value is -1. |
| Force Pixel Format UI | The Force Pixel Format UI value is an index of the pixel format for the interface, as seen in the PixelFormat pane of the Viewer Info window in MotionBuilder. Double-click the field to enter a value. This setting does not affect the Viewer window display, it affects only the interface. The default value is -1. |
| Viewer Info | Click the Viewer Info button to view the version and capabilities of the OpenGL implementation of your computer as well as the Pixel Format setup. See Viewer Info window. |
The Share Display List preference settings let you set default values for the Share Display List. The following table describes the Share Display List default preference settings.
| Share Display List setting | Description |
|---|---|
| Use Share Display List | The Use Share Display List menu lets you choose options that concern the use of your display. If you choose Test, the static geometry is sent to the video driver or card only once for the whole session. Doing this speeds up the display of static geometry with no effect on skinned or shaped models. Select No from the menu only when using problematic or old video drivers or cards. The default option is Test. |
| Use Display List For Curves | Activate the Use Display List For Curves option to activate hardware acceleration for displaying curves in the FCurves window. The default option is active. |
| Use Display List For Surfaces | The Use Display List For Surfaces option is like the Use Share Display List but applies to Patches and NURBS. If you select Test from the Use Share Display List menu, then activate Use Display List For Surfaces option, the non-deformed patches and NURBS uses the display list. Disable this option only when using problematic or old video drivers or cards. The default option is active. |
| Use Line Stipple | The Use Line Stipple option lets you use stipple or dotted lines in region selection and camera-safe areas. Disable this option only when using problematic video drivers or cards. In certain conditions, some newer video drivers or cards have had machine freeze problems when using line stipple. These problems usually occur when global anti-aliasing is used. The default option is active. |
The Video in Camera Background preference settings contain the Drawing Method menu, which lets you choose what type of camera background display is used as the default. The following table describes the Video in Camera Background preference settings.
| Video in Camera Background settings | Description |
|---|---|
| Test | Loads the camera background image in texture memory before displaying. This method is the best for displaying static images. This setting is the default selection |
| Texture | Loads the camera background image in texture memory before displaying. This method is the best for displaying static images. |
| Draw | Use the Draw option for video images, as it does not use texture memory. The Draw option transfers the background image from the main memory to the video memory. The texture video memory is then updated each time the video frames change. This method is the fastest in most “reflection on video” cases, or if your video is used for texturing geometry. |
For additional information about camera backgrounds, see Back Plate pane.
