WebFeb 12, 2016 · Functions that perform a download operation, a pixel pack, will use the buffer object bound to the GL_PIXEL_PACK_BUFFER. These functions only use buffer objects if one is bound to that particular binding point when the function is called. If a buffer is bound, then the pointer value that those functions take is not a pointer, but an offset … WebYou can render Metal or OpenGL content into either view by initializing a CVPixelBuffer that operates as an interoperable texture. When you enable the pixel buffer’s Metal and OpenGL compatibility flags, the textures are capable of being drawn to—and presented by—either rendering technology.

Pixel data can be read from a framebuffer and stored into CPU memory (or a buffer object). The framebuffer being read from is the framebuffer bound to GL_READ_FRAMEBUFFER; remember that binding to GL_FRAMEBUFFER binds to both the read and the draw.
