Warnung.png Delphi is already shipping with an OpenGL header, but that header is outdated and also buggy. Therefore we urge everyone to NOT use that header, especially as it lacks most of OpenGL's current functionality.

The DelphiGL header

To compensate for the flaws of the outdated and buggy default header that is shipped with Delphi, the (german) Delphi OpenGL Community is providing it's own header that's permanently updated to provide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. 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.

It includes all OpenGL functions (currently up-to and including OpenGL 4.2) as well as all GLU (OpenGL Utility Libary) functions and supports all ARB, EXT, NV and ATI extensions. It also includes additional, though lesser common extensions from other vendors like Apple, HP and SGI.

A 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).

.NET support

Due to lack of interest, .NET support has been removed as of header version 2.1!

Info DGL.png The .Net header won't be developed any further, but reported errors may be fixed. So new OpenGL functionality can only be found in the normal header.

Initializing function pointers (crucial)

Along with the removal of .NET support, support for loading methods dynamically has also been removed and is no longer possible with the standard header. So it's crucial to call either AtivateRenderingContext or ReadExtensions alongside with ReadImplementationProperties in your application before accessing any of the OpenGL functions. Otherwise you'll likely be prompted with an access violation at address 0x00000000.

So if you get such an access violation please check if you called the above functions!

Example for initializing the OpenGL function pointers (needs to be called before you access any OpenGL functions) :

procedure OpenGLInit;
 InitOpenGL; // Don't forget, or first gl-Call will result in an access violation!
 MyDC := GetDC(...);
 MyRC := CreateRenderingContext(...);
 ActivateRenderingContext(MyDC, MyRC); // Necessary, will also load function pointers for all extension

Example for finishing the OpenGL render context (should be called before quitting your application) :

procedure OpenGLFinish;
 DeactivateRenderingContext; // Deactivates the current context
 ReleaseDC(Handle, myDC);

(Supports OpenGL 4.3, works with Delphi 4 and up and Freepascal))

For Delphi 3 users : Mars has posted a version of the dglOpenGL.pas that will work with Delphi 3, you can get it here :

There is also an inofficial version of this headers for C++.
