![]() In some ironic turn of events, I myself just a few days ago added some functionality to my glx_hook hack which actually allows to modify the context an application is requesting without having to modify the source code. Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller glxinfo give me that parameters: OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Desktop OpenGL version string: 3.0 Mesa 10.1.3 OpenGL shading language version string: 1. Your example glxgears will simply generate a lot of GL errors and only show a black screen wehn run in core profile, because it is using display lists and immediate mode rendering commands and the fixed-function pipeline, which are all not available in core profile OpenGL.Īllthough it is most likely quite useless, to make a program use core profile OpenGL which doesn't request it, you either can modify the source code, or you can somehow interfere with its context creation operations. In any case, if the program is not written for OpenGL core profile, is will most likely not function correctly, because a lot of deprecated legacy functionality is simply not available in core profiles. ![]() If the program uses legacy context creation, it does either not know about newer GL functions (and will not be able to make use of them as a consequence), or it is just broken and simply assumes to get some newer GL version which is nothing a program can rely on, as per the spec. Is there a way to start OpenGL programs with core 3.3 profile? Technically, mesa llvmpipe simply does not support compatibility profiles. Intel® Clear Video HD Technology, like its predecessor, Intel® Clear Video Technology, is a suite of image decode and processing technologies built into the integrated processor graphics that improve video playback, delivering cleaner, sharper images, more natural, accurate, and vivid colors, and a clear and stable video picture. Profiles were introduced in OpenGL 3.2, even if mesa's interpretation of that slightly differs. Only old programs which use the legacy context creation (so they don't even know or care about the existence of different profiles) will get this version.Īctually, OpenGL 3.1 compatibility profile does not even exist. Unfortunately, any OpenGL program starts only in OpenGL 3.1 mode. ![]()
