Open GL capability has become a key part of the Avionics Ecosystem. As shown below the Eco system is always in flux. The maker of the Open GL capability shown in the drawing in this case is no longer exists as an independent entity. Open GL (Open Graphics Library) is the computer industry's standard application program interface (API) for defining 2-D and 3-D graphic images. Prior to OpenGL, any company developing a graphical application typically had to rewrite the graphics part of it for each operating system platform and had to be cognizant of the graphics hardware as well. With OpenGL, an application can create the same effects for safety-critical avionics display applications For some excellent information on this topic see: http://www.opengles-book.com/
