OpenGL ES 2.0中的glFenceSync替代 [英] glFenceSync alternative in OpenGL ES 2.0

问题描述

我看到glFenceSync在OpenGL ES 2.0中不存在，它仅在OpenGL ES 3.0中添加.

I see that glFenceSync does not exist in OpenGL ES 2.0, it was added only in OpenGL ES 3.0.

除了残酷的力量glFinish之外，OpenGL ES 2.0是否提供CPU和GPU之间的同步的任何替代选择?

Does OpenGL ES 2.0 offer any alternative of syncing between CPU and GPU, aside from the brutal force glFinish?

推荐答案

在glext.h中.

GL_API GLsync glFenceSyncAPPLE(GLenum condition, GLbitfield flags) __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_6_0);

我很确定这就是您想要的.无论如何，仅在iOS 6.0或更高版本上可用.

I am pretty sure this is what you want. Anyway available only on iOS 6.0 or later.
