Simple scene is rendered to the framebuffer 39 object in such way that all allocated buffers will be exercised. Multisampled 40 colorbuffer contents are then resolved to non-multisampled renderbuffer 41 using glBlitFramebuffer() and read from there using glReadPixels(). 42 43 Resulting image is compared agaist an image produced by a reference renderer. 44
