Finally, unneeded data is discarded. For example, GL_RED discards the green, blue, and alpha components, while GL_RGB discards only the alpha component. GL_LUMINANCE computes a single component value as the sum of the red, green, and blue components, and GL_LUMINANCE_ALPHA does the same,...

For example, it seems that the user is obliged to manage the redrawing of the window when another window application is recovering the GLUT window. That is why I am interested in glReadPixels and glDrawPixels functions. Does someone has some experience and advices about this problem ? IN...

glReadPixels使用示例 来源于glfw源码example目录中的offscreen.c . 会在同级目录下生成渲染后的图片...实现css图片水平翻转、垂直翻转 IE: 水平翻转: filter:filph 垂直翻转: filter:FlipV 同时水平垂直翻转 其他浏览器: 水平翻转: 垂直翻转: filter:FlipV 同时水平垂直翻转......
来源于glfw源码example目录中的offscreen.c . 会在同级目录下生成渲染后的图片...glReadPixels翻转图片 用Opengl的接口glReadPixels去读取内存并保存为ppm格式时,会发现图片是倒置的,也就是需要一个逆置或者flip操作, 我使用glReadPixels的方式如下: flip代码如下:...IOS...
