用X电话进入GLX后方缓冲?
原标题:Rendering into GLX back buffer with X calls?

I m playing around with GLX and xlib and I m curious about rendering using straight X calls on top of an openGL buffer. The glx intro clearly says that:

LX 大型X服务器提供开放式电离层图像。 与这些视像相联的衍生工具也可用于使用核心X射线器或符合所有核心X视线的其他X延伸。

确实,我能够简单地以某种雨水效应为蓝色,然后用Xlib电话取而代之。 However,GLX将X窗延伸到后方缓冲地带,在我直接向窗户投放之前,我不得不向前方冲。 我的问题是:在开放后,能否利用X向back<>> /em>缓冲提供。 GL是与它一起进行的,然后向前线转移这一缓冲地带,从而给我的露头和公开的电击机免费提供。 GL和X图表?

最佳回答

我认为答案是没有的,但也许有一些替代办法。

你可以以图象(把X和GL编成图,然后把地图带给你的X窗)来做另一层双bu。 如果你正在玩世俗的游戏,但你所描述的内容可能并不重要,这很可能给你带来 frame。

你们还可以利用开罗为客户提供记忆缓冲,为背景提供甲型频道。 然后将结果上载到GL,并在你的背景中加以描述。 Clutter工具包在其中一部分内容中发挥了作用。
