理论上,mesa 10.0.1 应该支持 OpenGL 3.3,但目前我只得到 3.0 的支持.
In theory, mesa 10.0.1 should support OpenGL 3.3 but currently I'm only getting 3.0 support.
glxinfo 给出了一些令人困惑的结果...
glxinfo gives some confusing results...
[pdel@architect build]$ glxinfo | grep -i opengl
OpenGL vendor string: Intel Open Source Technology Center

OpenGL core profile shading language version string: 3.30
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile

谁能解释核心配置文件版本字符串"和版本字符串"之间的区别以及它们为何不同?
Can anyone explain the difference between the "core profile version string" and the "version string" and why they're different?
它就在发行说明中:
OpenGL 3.3 仅如果在创建上下文时请求,则可用,因为不支持兼容性上下文.
它看起来像 glxinfo
首先尝试获取支持的最高核心配置文件信息,然后返回到非核心.
It looks like glxinfo
first tries to grab the highest supported core profile information and then drops back to non-core.
所以你会得到两组版本,一组用于核心配置文件,另一组用于非核心配置文件.
So you get two sets of versions, one for a core profile and another for a non-core profile.
如果您想在 Mesa 下使用 OpenGL 3.3,您必须创建一个核心配置文件.
If you want OpenGL 3.3 under Mesa you must create a core profile.
这篇关于核心配置文件与版本字符串?在 mesa 10.0.1 中只获得 GLSL 1.3/OGL 3.0的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持html5模板网!
