CHAPTER 3 How Do I run demos?

c:\opengl\lib must be added to the LIBPATH statement in your config.sys

If you are running OS/2 Warp, you must have multimedia installed. You should have a line like the following in config.sys:

DEVICE=c:\mmos2\ssmdd.sys

While OpenGL does currently work on most 2.1 systems, eventually it will only be supported on Warp.

You must be running in 8 bit (256 color) , 16 bit or 24 bit mode.

Some demos need flags. Check the source code to see what flags you should pass:

wave -db -dr

• -db for double buffered
• -dr for direct rendering (-ir for slower indirect rendering)
