Replaced OpenGL12 with SDL's gl/glu/glext units because OpenGL12 was removed from SDL (several years ago? Last update was done in 2004). In addition OpenGL12 was very buggy (see last commit). The new units support OpenGL up to version 2.0 (extensions must be loaded first, see UGraphic.LoadOpenGLExtensions). At the moment, only 1.2 extensions are loaded. Some constants, that were introduced in OpenGL 1.2 and above (like GL_BGR or GL_CLAMP_TO_EDGE) are in glext.pas, so check this file first for missing constants.

The MacOS build depends on OpenGL12.pas but has its own file in the MacOSX/Wrapper folder instead of using the JEDI-SDL one. Sorry, that I broke MacOSX build for now but it should be no problem to get this working again.

-//----------------------------------------------------------------------------------------------------------------------

-//

-//  This is an interface unit for the use of OpenGL from within Delphi and contains

-//  the translations of gl.h, glu.h as well as some support functions.

-//  OpenGL12.pas contains bug fixes and enhancements of Delphi's and other translations

-//  as well as support for extensions.

-//

-//  NOTE: In order to fully support multi thread rendering it is necessary to hold all

-//        extension address in threadvars. For single threaded applications this would be an

-//        unnecessary time penalty, however. Hence there is a compiler switch to

-//        allow single threaded OpenGL application to use vars while multi threaded applications

-//        will use threadvars. By default the switch MULTITHREADOPENGL (see compiler switch under der interface keyword)

-//        is not active and must explicitly enabled to take effect.

-//

-//----------------------------------------------------------------------------------------------------------------------

-//

-// function InitOpenGL: Boolean; 

-//   Needed to load the OpenGL DLLs and all addresses of the standard functions.

-//   In case OpenGL is already initialized this function does nothing. No error

-//   is raised, if something goes wrong, but you need to inspect the result in order

-//   to know if all went okay.

-//   Result: True if successful or already loaded, False otherwise.

-//

-// function InitOpenGLFromLibrary(GL_Name, GLU_Name: String): Boolean; 

-//   Same as InitOpenGL, but you can specify specific DLLs. Useful if you want to

-//   use different DLLs than the default ones. This function closes previously

-//   loaded DLLs before it tries to open the new libraries.

-//   Result: True if successful, False otherwise.

-//

-// procedure CloseOpenGL; 

-//   Unloads the OpenGL DLLs and sets all function addresses to nil, including

-//   extensions. You can load and unload the DLLs as often as you like.

-//

-// procedure ClearExtensions; 

-//   Sets all extension routines to nil. This is needed when you change the Pixelformat

-//   of your OpenGL window, since the availability of these routines changes from

-//   PixelFormat to Pixelformat (and also between various vendors).

-//

-// function CreateRenderingContext(DC: HDC; Options: TRCOptions; ColorBits, StencilBits, AccumBits, AuxBuffers: Integer; 

-//   Layer: Integer; var Palette: HPALETTE): HGLRC; 

-//   Sets up a pixel format and creates a new rendering context depending of the

-//   given parameters:

-//     DC          - the device context for which the rc is to be created

-//     Options     - options for the context, which the application would like to have

-//                   (it is not guaranteed they will be available)

-//     ColorBits   - the color depth of the device context (Note: Because of the internal DC handling of the VCL you

-//                   should avoid using GetDeviceCaps for memory DCs which are members of a TBitmap class.

-//                   Translate the Pixelformat member instead!)

-//     StencilBits - requested size of the stencil buffer

-//     AccumBits   - requested size of the accumulation buffer

-//     AuxBuffers  - requested number of auxiliary buffers

-//     Layer       - ID for the layer for which the RC will be created (-1..-15 for underlay planes, 0 for main plane,

-//                   1..15 for overlay planes)

-//                   Note: The layer handling is not yet complete as there is very few information

-//                   available and (until now) no OpenGL implementation with layer support on the low budget market.

-//                   Hence use 0 (for the main plane) as layer ID.

-//     Palette     - Palette Handle created within function (need to use DeleteObject(Palette) to free this if <> 0)

-//   Result: the newly created context or 0 if setup failed

-//

-// procedure ActivateRenderingContext(DC: HDC; RC: HGLRC); 

-//   Makes RC in DC 'current' (wglMakeCurrent(..)) and loads all extension addresses

-//   and flags if necessary.

-//

-// procedure DeactivateRenderingContext; 

-//   Counterpart to ActivateRenderingContext.

-//

-// procedure DestroyRenderingContext(RC: HGLRC); 

-//   RC will be destroyed and must be recreated if you want to use it again.

-//

-// procedure ReadExtensions; 

-//   Determines which extensions for the current rendering context are available and

-//   loads their addresses. This procedure is called from ActivateRenderingContext

-//   if a new pixel format is used, but you can safely call it from where you want

-//   to actualize those values (under the condition that a rendering context MUST be

-//   active).

-//

-// procedure ReadImplementationProperties; 

-//   Determines other properties of the OpenGL DLL (version, availability of extensions).

-//   Again, a valid rendering context must be active.

-//

-// function HasActiveContext: Boolean; 

-//   Determines whether the calling thread has currently an active rendering context.

-  Revision 1.2  2004/04/05 09:59:46  savage

-  Changes for FreePacal as suggested by Marco

-

-  Revision 1.1  2004/03/30 21:53:55  savage

-  Moved to it's own folder.

-

-  Revision 1.6  2004/02/20 17:26:19  savage

-  Extensions are now loaded using SDL_GL_GetProcAddress, thus making it more cross-platform compatible, but now more tied to SDL.

-

-  Revision 1.5  2004/02/15 22:48:36  savage

-  More FPC and FreeBSD support changes.

-

-  Revision 1.4  2004/02/14 22:36:29  savage

-  Fixed inconsistencies of using LoadLibrary and LoadModule.

-  Now all units make use of LoadModule rather than LoadLibrary and other dynamic proc procedures.

-

-  Revision 1.3  2004/02/14 00:23:39  savage

-  As UNIX is defined in jedi-sdl.inc this will be used to check linux compatability as well. Units have been changed to reflect this change.

-

-  Revision 1.2  2004/02/14 00:09:19  savage

-  Changed uses to now make use of moduleloader.pas rather than dllfuncs.pas

-

-  Revision 1.1  2004/02/05 00:08:20  savage

-  Module 1.0 release
