New functionality in the OpenGL 4.3 specification includes:
#OSX OPENGL 4.3 UPDATE#
Twenty years since the release of the original OpenGL 1.0, the new OpenGL 4.3 specification has been defined by the OpenGL ARB (Architecture Review Board) working group at Khronos, and includes the GLSL 4.30 update to the OpenGL Shading Language.
#OSX OPENGL 4.3 FULL#
The full specification is available for immediate download at. The OpenGL 4.3 specification contains new features that extend functionality available to developers and enables increased application performance. OpenGL 4.3 integrates developer feedback and continues the rapid evolution of this royalty-free specification while maintaining full backwards compatibility, enabling applications to incrementally use new features while portably accessing state-of-the-art graphics processing unit (GPU) functionality across diverse operating systems and platforms.
#OSX OPENGL 4.3 DRIVERS#
I know my graphics drivers only support 4.2 right now, but I had thought that GLX was designed to throw an error, give a NULL context, and let your program keep going, but instead it can't get past the failed creation of the context.Full backwards compatibility maintained API specification and reference documentation available nowĪugust 6th, 2012 – Los Angeles, SIGGRAPH 2012 – The Khronos™ Group today announced the immediate release of the OpenGL® 4.3 specification, bringing the very latest graphics functionality to the most advanced and widely adopted cross-platform 2D and 3D graphics API (application programming interface).

The method I use (#2) fails immediately upon creation of the 4.3 context.

Using trial and error, where I start from the newest version (4.3, but my GTX 460 only supports up to 4.2, even though I updated the drivers), and if that fails (which I detect by checking for SDL to return a NULL context), I lower the version number and try again. There are two methods I can think of:ĭetecting the latest supported version of OpenGL and using that, but I can't think of any way to do that. This way I can use the newest features of OpenGL where they are relevant and useful, but also support older hardware.
#OSX OPENGL 4.3 DRIVER#
I'm using SDL2 and C++11 to build a game engine (just as a personal project, for fun and for practice), and one of the things I want to do is try and have the graphics driver use the latest supported version of OpenGL, and vary how the graphics portion of the engine renders based on the version.
