This book provides an overview of OpenGL function and describes in detail the window and input interface that integrates OpenGL with the Presentation Manager. Application developers can use this interface to:

• Create and prepare an OpenGL context for rendering
  
• Swap a window's front and back buffers
  
• Select a color palette for a color index context
  
• Integrate GPI and OpenGL rendering and fonts

The interface provides much the same functionality as the OpenGL window interfaces for X Windows and Microsoft systems.
