The dglOpenGL.pas is distributed unter the terms and conditions of the Mozilla Public License Version 1.1. It also includes additional, though lesser common extensions from other vendors like Apple, HP and SGI.Ī special feature of this header are boolean variables for each included extension that are flagged upon initialisation (those boolean vars carry the same as their corresponding extensions), so you can quickly check whether an extension is support or not (instead of checking the strings returned by glGetString/en). It includes all OpenGL functions (currently up-to and including OpenGL 4.4) as well as all GLU ( OpenGL Utility Libary) functions and supports all ARB, EXT, NV and ATI extensions. This makes updating to a new header version easy (usually backwards compatibility is preserved), and it's even possible to use the header with other pascal compilers like Freepascal. To compensate for the flaws of the outdated and buggy default header that is shipped with Delphi, the (german) Delphi OpenGL Community is providing it's own header that's permanently updated to provide steady support for new OpenGL features and functionality.
