Hi everyone, i start reading the “Blue Book”, in chapter2, i can’t understand
"Pixels
During the previous stage of the OpenGL pipeline, fragments are converted to pixels in the frame buffer. The frame buffer is actually organized into a set of logical buffers—the color, depth, stencil, and accumulation buffers. The color buffer itself consists of a front left, front right, back left, back right, and some number of auxiliary buffers. You can issue commands to control these buffers, and you can directly read or copy pixels from them. (Note that the particular OpenGL context you’re using may not provide all of these buffers.)
What is the Color Buffer? Why say it contains other buffer, like front right,front left…? Thanks for help in advance.
