When you select this option, the last five fonts you have assigned to

the current document are displayed at the top of the font list.

3D view – Use OpenGL

Specifies that all 3D graphics from Draw and Impress will be

displayed in your system using OpenGL-capable hardware. If your

system does not have OpenGL-capable hardware, this setting will be

ignored.

3D view – Use OpenGL – Optimized output

Select this option for optimized OpenGL output. Disable the

optimization in case of graphical errors of 3D output.

3D view – Use dithering

The Use dithering option uses dithering to display additional colors

when the computer’s graphics system offers less than the optimal 16

million (24-bit) colors. Dithering creates the illusion of new colors

and shades by varying the pattern of color pixels. Varying the

patterns of black and white dots, for instance, produces different

shades of gray.

Note

Internally, 3-D graphics are always created with 16 million

colors (24-bit color depth) and dithering can be used to

compensate when fewer actual colors are available. Without

dithering, several bits of color information would be omitted,

leading to significantly reduced image quality.

3D view – Object refresh during interaction

Specifies that if you rotate or move a 3-D object, the full display is

rotated or moved and not a grid frame.
