Here is GLTemplate, a sample Windows application that opens an OpenGL window and draws a colored triangle. You can use it to experiment with OpenGL calls. The methods you'll want to look at are OnDraw(), SetupGLParameters(), and SetupProjection() within the CGLTemplateView class.[an error occurred while processing this directive]
The following is a list of the example programs found in the OpenGL Programming Guide (Addison-Wesley Publishing Company). The examples will probably not run unless you are on a Silicon Graphics workstation, but reading the code can still be useful (and you can copy the code into GLTemplate to try it out). These examples are from the first edition of the Guide, so they may not correspond exactly to the second edition.
You can also get a zipped copy of all these files.
