Do incomplete dominance is also called supplementary gene interaction?

In incomplete dominance ,neither dominant nor recessive character is expressed in the F1 generation.Instead a intermediate character is expressed. IN the same way in supplementary gene interaction ,the F1 generation shows a intermediate character of the parent.
I want to know whether in incomplete dominance one character masks the other or something different happens during the F1 generation?
