opengl - What is the difference between a sample, a pixel and a fragment? -


i still can't wrap head around differences there between sample/pixel/fragment.

since fragment shader executes per pixel, think fragment refers pixel, correct? can give me example , definition of each one?

a pixel screen element. fragment corresponding portion given geometric primitive +- covering pixel. antialiasing (and more) several samples can pickup in pixel.

a pixel values mean of samples values, , fragments several triangles might contribute given pixel.
