    Source, destination in glBlendFunc

    my question is simple.
    Can anyone clarify what source and destination mean in glBlendFunc?

    is source the one object behind or ... the opposite meaning?

    thanks.

    source is the pixel color about to be displayed and destination is the pixel color that is already in the color buffer.
