Can anyone point me to an application that will display the OpenGL features. At issue is that I can run the BoltHenge demo in full screen fine, but when trying to run the Water demo I get an error message that the Requested Mode is not supported. My card is a Creative Labs Annilator 2 (GeForce 2). Any pointers to a program (or even an explanation of the difference in the applications would be appreciated).

The best (only ?) documentation for this is at MSDN.
It is tricky with fullscreen in Windows but I think tutorial 31 has been updated with some better code.

So are there different full screen modes for OpenGL?

I''m just beginning to code for OpenGL, but from what little I''ve read either your graphics card supports fullscreen or it doesn''t.

Just don''t understand why the BoltHenge can do fullscreen and the Water can''t.

Yes, there a lot of modes that can be set like color depth, supported buffers and so on.

Some old Vodoo cards do not support fullscreen.

BoltHenge has probably better code for switching to fullscreen mode than Water. If you have the source codes can you try to update the Water code with code from BoltHenge.

A look at libraries such as GLUT can also give some hints.
