清除/释放OpenGL ES缓冲区 [英] Clearing/releasing OpenGL ES buffers

问题描述

我要在OpenGL ES 1.1 iOS应用程序中创建额外的帧缓冲区和渲染缓冲区，以进行屏幕外渲染.当我渲染到其他渲染缓冲区时，我开始在XCode控制台中看到内存警告. 释放"，清除"等这些额外缓冲区的正确方法是什么?

I'm creating an extra framebuffer and renderbuffer for offscreen rendering in my OpenGL ES 1.1 iOS app. When I render into the additional renderbuffer I start to see memory warnings in the XCode console. What is the proper way to "release", "clear" etc these additional buffers?

我尝试了glClear(GL_COLOR_BUFFER_BIT)，但是内存警告仍在继续.注释掉渲染代码会使警告消失.

I experimented with glClear(GL_COLOR_BUFFER_BIT) but the memory warnings continued. Commenting out the rendering code causes the warnings to go away.

推荐答案

我不知道您的意思， glDeleteFramebuffers 和 glDeleteRenderbuffers ，可能带有一些OES后缀.

I don't know what you mean, glClear clears the content of the buffer (color, depth, stencil, whatever, depending on the bit flags) to a specific value. If you want to delete the buffers and free their resources, once you're finished with them, use glDeleteFramebuffers and glDeleteRenderbuffers respectively, maybe with some OES suffix.

否则，我不知道您在说什么，如果这两种情况都不适用，您应该忽略这种愚蠢的警告.

Othwerwise I don't know what you're talking about else and if these two cases don't apply you should just ignore such stupid warnings.
