问将OpenGL渲染保存到图像文件EN您可以在渲染和交换后使用glReadPixels：
原因与解决: 修改后代码: constintwindowsWidth=65;constintwindowsHeight=65;GLFWwindow*window=glfwCreateWindow(windowsWidth,windowsHeight,"LearnOpenGL",NULL,NULL);// render …cv::Matimg(2*windowsHeight,2*windowsWidth,CV_8UC3);glPixelStorei(GL_PACK_ALIGNMENT,(img.step&3)?1:4);glPixelStorei(GL_PAC...
the corner radius does not apply to the image in the layer’s contents property; it applies only to the background color and border of the layer. However, setting the masksToBounds property to true causes the content to be clipped to the rounded ...

从其构造函数中可以看出,OpenGL Render线程是一个单例,同一个进程只有一个RenderThread,RenderProxy 通过mRenderThread引用该单例,将来需要提交任务的时候,直接通过该引用向RenderThread的Queue中插入消息,而RenderThread主要负责从Queue取出消息,并执行,比如将OpenGL命令issue提交给GPU,并通知GPU渲染。在Android Profile的CPU工...

To bring some life to the currently black abyss of our game world, we will render sprites to fill the void. A sprite has many definitions, but it's effectively not much more than a 2D image used together with some data to position it in a larger world (e.g. position, rotation, and...
