"One of the cool features of Windows NT¨ that has finally made it to Windows 95¨ is the OpenGL graphics API. OpenGL is pretty much the industry standard for high-quality 3D graphics applications. If you admired the dinosaurs in Jurassic Park, then you were looking at an OpenGL application. A big advantage of OpenGL is that it's platform-independent; it's available on a variety of hardware platforms and operating systems, including Windows 95, Windows NT, OS/2, DEC's AXP and Open VMS, and X Windows."
