WebOpenGL allows you to combine those into one image, so we'll have to create just one more before we can use the framebuffer. Although we could do this by creating another texture, it is more efficient to store these buffers in a Renderbuffer Object, because we're only interested in reading the color buffer in a shader. WebOpenGL provides a number of functions for accessing images through image variables. Image operations have "image coordinates", which serve the purpose of specifying …
