Graphics Preferences
Most users will never need to change the graphic settings. The settings affect the display of the Graphical Tooth Chart in the Chart module and the Graphical Perio Chart.
They are specific to the computer where you are working, allowing you
to set different graphics preferences for each computer.
In the Main Menu, click File, Graphics.
DirectX: This is the latest 3D Microsoft technology. It is recommended if possible. This setting is required to view the Graphical Perio Chart.
OpenGL: This is the 3D technology that we used in the past. It works well, but
the Graphical Perio Chart will not be available.
Simple 2D:
Can be used if neither DirectX or OpenGL can be made to work. For
example, when using a remote connection, such as Microsoft Terminal
Services, GoToMyPC, etc. The simple tooth chart will eliminate all
slowness issues over the remote connection. But the tooth chart will
not look as nice.
Options for 3D Tooth Chart: These are only changed if the Graphical Tooth Chart is not working properly.
- Open
GL Filters: Filter the list of graphic formats. These
options are only enabled when OpenGL is the selected option.
- Hardware Acceleration: Use one of these formats if you have a graphics card. If
you have a graphics controller that is integrated into the
motherboard, you might not use this option. In practice, it works
best to try it both ways to see which gives you the best result.
-
Use Double-Buffering: With these formats, the redraw of the graphics is
hidden in a second buffer. This eliminates flicker.
- Show All Formats: All available formats
- Graphics
Formats: Click on the format to use for the tooth chart.
The selected format number shows at the top.
Troubleshooting
If DirectX is not working properly
1. Install the latest DirectX runtime: http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=2da43d38-db71-4c1b-bc6a-9b6652cd92a3.
2. Install all express/critical Windows Updates.
3. Update the graphics card driver using one of the following:
a. Try to locate the driver from the computer manufacturer's website.
b. Try to locate the driver from the graphics card manufacturer's website.
c. Try to use Windows Update to update the graphics card driver.
4. Install the latest DirectX SDK (only do this if DirectX is
still not working). If using Windows 8, use this link: http://msdn.microsoft.com/en-us/windows/desktop/aa904949. If using a different version, use this link: http://www.microsoft.com/download/en/details.aspx?id=6812.
If you cannot get into Graphic Preferences on your computer
You canc hange the graphic setting from a different computer. Click Setup, Computers.
Citrix Users: Because
of the way Citrix renders graphics, Citrix users cannot use DirectX or
hardware acceleration. For best results, select a buffered graphics
mode, or Simple 2D mode. Otherwise, the teeth with flicker every
time you click on the tooth chart.
If you experience a major error while using this interface, see Troubleshooting.
More Terminology
(Only for the very curious)
Windowed: Can be drawn on the screen. There are some graphics formats that cannot be drawn to the screen.
Palette: Instead of millions of colors, there is just a small palette of colors available.
Depth bits:
This is how the coordinates on the Z axis are stored. If there are not
enough depth bits available, overlapping doesn't work properly.
Color bits: The more the better.
