Installing OpenGL
To install OpenGL, double-click the "Installer" icon in the "OpenGL Install" folder and follow the on-screen instructions.
Using OpenGL
How OpenGL uses memory
OpenGL is a shared library. When no applications that rely on OpenGL are open, the library does not take up memory space (RAM). Once OpenGL -based application is open, the amount of memory taken up by the shared library doesnﾕt increase if other OpenGL -based applications are launched. Of course, each application will take up memory according to their size and the complexity. The memory taken up OpenGL becomes available when you quit all OpenGL -based applications.
While an OpenGL application is open, the OpenGL library allocates memory from "temporary memory." This memory shows up in the "About This Computer" window as memory used by the application. When you quit the application, the memory becomes available.
About Apple Game Sprockets
Some third-party applications may need Apple Game Sprockets files installed in the Extensions folder within the System Folder. These files provide the support that many games need to interact with joysticks, networks, and monitors. If you install any games on your computer, they may install earlier versions of Apple Game Sprockets. To make sure that you are using the latest versions, remove any copies of DrawSprocketLib, NetSprocketLib, InputSprocketLib, or SoundSprocketLib that are not in the Extensions folder within the System Folder.
Reinstalling OpenGL
To reinstall OpenGL, open the "OpenGL Install" folder and double-click the "Installer" icon.
Removing OpenGL
If you wish to remove OpenGL, follow these steps:
1. Open the "OpenGL Install" folder and double-click the Installer icon.
2. Choose Custom Remove from the pop-up menu.
3. Click the box next to each item to put a check in it.
4. Click Remove.
5. Restart your computer.
