Notes

The DesktopOpenGLSurface control and the OpenGL module are based on the OpenGLSurface plug-in from Tinrocket, LLC at http://2002-2010.tinrocket.com/software/openglsurface/index.html.

The OpenGL module contains all the OpenGL calls, functions, and constants that you will need. See http://www.opengl.org/ for the OpenGL documentation. The online version of the Red Book for OpenGL 1.1 is available at http://www.glprogramming.com/red.

Additional information:

  • OpenGL uses a per-thread context.
  • All of the functions in the OpenGL module affect the current context.
  • The current OpenGL context is undefined outside of an DesktopOpenGLSurface Opening, Resized or Render event.
  • DesktopOpenGLSurface.MakeCurrent can be used to make a specific OpenGLCanvas the current context.
