ForceWare 181.00: Five New OpenGL Extensions and How To Create an OpenGL 3.0 Rendering Context

In order to do some tests for the upcomming version of FurMark, I took the time to install the new ForceWare 181.00 with a GeForce 8800 GTX under Windows XP SP2 32-bit. In comparison to ForceWare 180.42, this new set of graphics drivers for GeForce 6/78/9/GTX200 adds 5 new extensions:

NVIDIA ForceWare 177.89: OpenGL Extensions and OpenGL 3.0 Code Sample

[French] Voici la liste des extensions OpenGL supportées par les pilotes Forceware 177.89 WinXP 32 pour une GeForce GTX 280. [/French] [English] Here is the list of OpenGL extensions supported by Forceware 177.89 WinXP 32 drivers for a GeForce GTX 280. [/English]

[French]
Les ForceWare 177.89 sont les premiers pilotes à offrir le support OpenGL 3.0. Mais pour le moment, ce support n’est pas officiel. Il faut l’activer de manière logiciel grâce à l’utilitaire NVemulate de NVIDIA:

L’activation d’OpenGL 3.0 donne accès à une nouvelle extension WGL_ARB_create_context qui permet de créer un context de rendu OpenGL 3.0. Si vous souhaitez ouvrir la porte d’OpenGL 3.0, voilà le code nécessaire:

Forceware 177.89 are the first drivers to offer the OpenGL 3.0 support. But currently, this support is not official. We have to enable it thanks to NVIDIA’s NVemulate utility:

OpenGL 3.0 activation gives an access to a new extension: WGL_ARB_create_context.
This extension makes it possible to create an OpenGL 3.0 rendering context. If you wish to explore the new world of OpenGL 3.0, here is the necessary code:
[/English]

// wglCreateContextAttribsARB prototype.
typedef HGLRC (APIENTRYP PFNWGLCREATECONTEXTATTRIBSARBPROC)\
(HDC, HGLRC, const int*);
PFNWGLCREATECONTEXTATTRIBSARBPROC wglCreateContextAttribsARB;

// Get a pointer on the create context func.
wglCreateContextAttribsARB = \
(PFNWGLCREATECONTEXTATTRIBSARBPROC) \
wglGetProcAddress("wglCreateContextAttribsARB");

// Create an OpenGL 3.0 context.
HGLRC gl3Ctx = wglCreateContextAttribsARB(dc, 0, NULL);

//
// Do something with this opengl 3.0 rendering context.
//

// Delete the context
wglDeleteContext( gl3Ctx );	
gl3Ctx = NULL;

Ceci étant dit, voilà la liste des nouvelles extensions pour un contexte de rendu OpenGL 2.1 avec support OpenGL 3.0 activé:

That said, here is the list of the new extensions for an OpenGL 2.1 rendering context with OpenGL 3.0 support enabled:
[/English]

• GL_ARB_draw_instanced
• GL_ARB_half_float_vertex
• GL_ARB_framebuffer_object
• GL_ARB_geometry_shader4
• GL_ARB_texture_buffer_object
• GL_ARB_vertex_array_object
• WGL_ARB_create_context
